A story from a cloaky camper and an attempt to build a beast mode multi-boxing server.

21/04/2018
Hello Nerds!
 
Some of you may know me, some may not. Those that do will know I offer cloaky camping services over new eden. I do camping contracts / extort renters and focus my time hunting botters when the contracts are quiet. I offer PvP entities access to my cyno network to get dank kills and big escalations. From super carriers to Rattlesnakes.
 
The thing that got me into camping was hunting bots back in the dronelands a few years ago. I realised the most effective way to hurt them was to camp them 23/7, follow them around using locator agents. Eventually they had to rat with me in system. When they did I setup bubble traps etc and dropped blops and cleaned them up.
 
The 2nd thing I love about cloaky camping is the ability to counter Alliances (i feel its overpowered) intel channels / networks. Think about it. They have multiple intel toons dotted around the entrances to their pipes reporting hunters coming into the pipe allowing the PvE players to warp off and safe up. They even use external programs to collect this intel and give audible alerts. Cloaky camping is just the polar opposite. Dotting toons in their ratting pocket and giving me intel on whats going on in their system. As long as local chat exists so will cloaky camping. I'm pretty confident CCP share the same thought.
 
People probably think cloaky camping is easy. You are wrong. The prep work and behind the scenes work that goes into it is pretty immense. You are about to find out.
 
The hardware i'm currently running the 60 clients on is as follows:

Camper2:
 
How do you pay for 60 toons
I started with 10 campers and made ISK by other means. When I made new campers I invested ISK and started to Skill extract and plexing the toons. I also make a decent amount from people who pay me to camp others.
 
The Setup  
I manage the clients window positions and CPU allocation with ISBOXER. Its legal to use as long as you don't use input broadcasting. I boot up the clients with ISBOXER EVE Launcher. I copy the window positions / chat channels etc over using garpaui. I use remote desktop to manage the clients light cynos etc.
Example here
 
On both motherboards I had to under clock the processors as they were drawing too much power from the motherboard and causing the chipset to overheat. I think these motherboards are not beefy enough to support these 8 core processors. It caused the CPU to throttle reducing the clock speeds to 1.3Ghz and causing lag issues. I solved this problem by reducing the clock speed from 4Ghz to 3.6Ghz and reducing the CPU voltage. This reduced the heat by a really good amount and stopped the problems.
 
However, Me being me I wanted to expand and the camping pcs were running at full chat. So I needed a better piece of hardware to host these 60+ clients. So, while at Fanfest, I bidded on this R820 Server on ebay and won!
 
Specs:
 
The hardware should be able to support multiple clients. However i'm not too sure how eve is going to behave when I try and open 60 instances all in one OS. I have set myself up for a hell of a challenge! However, I feel like I got a pretty good deal on the server and DELL hold their value. I'm sure I can re sell it if the project fails.
 
Things to work out:
 
Things I will teach you guys
 
I'm learning too so your help input would be awesome! First question. Shall I just update this reddit post each time or create some sort of blog?
Old AMD FX Rigs
New Kit / with various bits I gathered to get started
 
Update 23/04/18
I have made some decent progress on this crazy project. I will give some breif updates here. I will get a blog up and running to post full details with how to's etc. Its probably way to long for reddit.
 
I have successfully installed some GPU's into the R810 AMD R9 280x and Nvidia GTX 970. I soldered some PCI-E cables to the PDB and it worked fine. The GTX sits nicely in the chassis however, the R9 280X is external atm using a PCIE x1 to x16 riser (from my bitcoin mining). Also I have managed to enable and use them both with passthrough in ESXI 6.5. Yes the GPU works with a x1 adaptor. WTF!
 
Freezing Problem with a single os install
If I try and run more than 40 clients in a single OS I the system freezes when loading up client 41. I have tried the following:
I cannot see why it is freezing. Is there any way to gather logs for the client? It doesn't appear to be a resource problem. Plenty of RAM / CPU and HDD isn't going crazy.
 
Here are some pics of the current progress:

Advice? Going a bit insane.

I have a simple set-up I've been trying to get running stable for about a week now. I have 2x nVIDIA GTX 980 and 2x Radeon 29 280X cards that I want to use.
I have previously used just the GTX 980s and they were stable for weeks. I recently acquired the 280s, and while I can't be certain, I think the cards are not at issue.
I also had two of the 980s and one 280 running in my desktop stable for quite some time, just as a tester. But for the actual mining rig, I was using old AMD AM3-based hardware. And I've had nothing but problems. Murphy's law.
First, I had a motherboard go out (ASUS M4A87TD EVO.) Luckily I had a spare. But the ASUS board had two native PCI-E x16 slots (one running at x1 speed,) and so I had been running the 980s both in the motherboard, and was using this riser extender to run the other cards, with molex->SATA risers (I don't have enough native 4-pin connectors to run without molex to SATA adapters.)
The "new" board (which is actually chronologically older and older tech) is a Gigabyte GA-MA785GM-US2H. It's also socket AM3 but only supports DDR2 memory; luckily I had old DDR2 available. This board also only has one x16 slot, so I am running 3 GPUs outside of the chassis with x16 risers.
It turns out after some nightmare of troubleshooting that one of the DDR2 DIMMs is probably bad. I don't have a replacement at the moment, but I've tried running everything with one DIMM.
I also have Virtual Memory (swap/page file) set to 16GB. I don't know why this is necessary, but other people mention it and NiceHash wouldn't let me run 4 cards without it.
Anyway, all works "fine;" I have the 280s set to 850MHz core clock and +20 power with 100% fans, and 100% fans and native clock on the 980s.
But I keep getting crashes. Before I had freezes, so I also changed out power supplies several times and tried everything you can think of. I don't think the issue is down to power any more, but I'm open to correction if anyone has a suggestion or tip.
For power, I'm using a 3 to 1 ATX-24 pin adapter, with a SeaSonic 620W as the master, and a Corsair 550W as the "slave." The SeaSonic powers the motherboard and the ATX12V for the CPU. It also powers the 3 SATA to molex adapters for the x16 risers, and the 8+6 pin PCI-E power connectors for the 280s.
The Corsair powers the HDD (this I have also suspected of causing problems but I have swapped HDDs and had the same issues, and I really need to get an SSD for this thing,) two 120mm intake fans, two 140mm exhaust fans, and the 6 pin PCI-E connectors for the 980s.
It doesn't seem to freeze anymore. It will mine just fine for a while but eventually I will get a BSOD, usually saying that the device driver has gone into an infinite loop. I believe this is the Crimson driver (I am using version 15.12.)
I've swapped CPUs and memory and HDDs and motherboards and I'm just almost at my wits' end about to tear my hair out trying to get this thing to run stably. I most likely just need to get all new mainboard/CPU/memory, but I can't do that at the moment, so I am looking for any advice/help I can get.
I would assume the driver is going into an infinite loop because it's polling hardware and not getting the response it expects or something like that, which could indicate a power or heat issue, but I don't know. And I've searched for the BSOD error and 90% of the results for "device driver went into an infinite loop" (paraphrasing) were related to AMD Crimson drivers. So that's been where my suspicion has been so far, and I've had other problems with getting the AMD stuff to work when I was initially setting it up. (And had problems with AMD/ATi drivers going back 20 years, ugh.)
So.. Any advice?
TL;DR: Running 2x GTX 980 and 2x R9 280X; keep getting BSOD about device driver going into an infinite loop after some time mining. Want to stab myself.

no post craping on this item unless you can find a cheaper one online

Pricing this one is abit on the difficult side but i figured i would start here and go from their.
This is a BEAST of a motherboard supports dual socket 2011 cpus and is the only mobo for this socket that will let you overclock them (bclk oc) I currently run dual e5-2670's on it and it handles every task i throw at it with flying colors. I have tested it with MANY operating systems including, 2008, 2008 R2, 2012 R2, win 10, ESXI 6.0 (majority of time), and Proxmox (basic testing) all of which it was COMPLETELY stable. However, this motherboard does have some damage in both of the sockets. socket 0 is missing 3 pins all of witch are redundant I believe they are all grounding pins. socket 1 is missing about 5 and some of those are redundent but some of them are related to dimm 4. dimm 4 of socket one does not work leaving you with only 11 out of the 12 dimms. This is the only damage that effects the functionality of the mobo the only other "damage" is VERY small and in no way effects the preformance or look of the mobo. Currently this is the only on I could find for sale anywhere and figured i would put it on the market in case anyone was interested. This is used in my daily rig and i use it for everything from virtualization to CAD and gaming with zero issues.

would like to keep until i sell the sr-x as its a important part of my main rig.

Made $1 Million mining. Want to Cash out. worried about being unemployed

Basically back in early 2016, I bought some second hand Radeon 7970s and r9 280x and been mining ETH since it pretty much launched. Back then you basically made like 1 ETH per GPU per day. Back then a 280x mined at like 27MH/s since the DAG was very small. Even my R9 270X mined at like 20MH/s.
I kept all this ETH, along with the free ETC, sold all of my ETH/ETC when it peaked at $400 last Summer and went all in BTC. BTC went 5x since that time. Also got the free bitcoin forks.
I kept cashing out a small amount with bitcoin ATMs and basically quit my job since it wasn't worth the hassle.
Now I want to buy a house but I am worried about sending $1,000,000 to an exchange like Gemini/Coinbase/Kraken/Bitstamp and have them freeze this BTC.
I am worried they will ask for employment papers and I've been unemployed since 2016.
All this money was made legally. However since I mined to an exchange instead of my personal ETH wallet, I might not be able to provide a signed message proving I am the one who mined those coins. Since all the coins were mined directly to my Poloniex account. I do have receipts for some RX 470s that I bought last year and wondering if its sufficent. Do I need to take photos of my mining rigs and show it to my exchange as proof?
I know I can buy USDT tether but I am worried that its not really backed by anything. I also don't know if any of the Bitcoin Future Options will be sufficient since they might carry crazy premiums for the puts.
Wondering if people had issues withdrawing large amounts.

My Consulting Rate Schedule / Experience - If you want serious work done or advice that would take me hours to explain

My background:
My Rates - I'll scale by age, makes sense to me
Note: If I don't like you, for whatever reason at this point, there is a 10 Eth / Hour Asshole surcharge These prices are completely arbitrary, pay them , don't pay them, I don't care. Going forward, if anyone PMs me in regards to help , they will just get a link to this post. Pretty much wrote all of this up to save myself time from 100 PMs a day from ungrateful people at /EtherMining
What you get: * 1 hr phone and / or video conference call. * Ask me how my day was, ask me technical question - your choice * 15m free phone / video call follow up * I am a reasonable guy, if I projected an issue to be done in x hours and it's not fixed by that time, I'll stay on the line until it is
You can pay me for my time & experience or you can spend 500 messing around with your own rigs yourself (Like I did) - It is completely your choice. This is more of an option for people who have extra crash and don't have time time to put in like I did.

Cheers,

-Epic™

Edit: Just if you can't Math ( as lots of people can't - no big deal ) EVERY 1/mhs you LOSE because your rig is not optimized Equates to .5 Eth / Month LOSS. Do the math on what you are losing. Here - 20/mhs loss = 10 Eth / Month * $8.25 ( Current Rate ) = $82.5. If Eth goes to $20 that is $200 per month on coins you lost ONLY because you did not apply the right settings for your cards. This should make my "fee" look cheap in comparison if you're running multiple cards. And if Eth goes to $1,000 in a few years like Bitcoin did, you will have some serious regrets.
PM: Pro Bono Consulting Client:
"My rates peak as high as 128MH/s.. so my average will probably be in the 115MH/s range. When I try the local/global-work code and/or setting the allocation percentage higher than 95%, I get errors. Can't remember what specifically.. something about failing to grab DAG info in one big chunk and 'bailing'."
PM: Pro Bono Consulting Client:
"Hey thank you for the help on etherminer. I finally got the 6-GPU rig up and running. Windows turned out to be more of a headache than Ubuntu so I went back to Linux and figured it out. As per your suggestion I am on ethermine.org using qtminer. (I'm actually offline at the moment, but everything is operational) I used the default qtminer code that tells all of the GPUs to work but it's not entirely clear what is happening. Each GPU appears to be working on the same 'problem'. Is that accurate? As opposed to having each GPU work more independently on a separate problem..? I set the GPU workload to 93%.. Fans to 90%.. everything running cool at ~50c The results of most of the mining calculations appear to get grouped and uploaded to the pool as some sort of 'piece of the puzzle'. Every so often there is a 'solution' with a 'nonce'. How does that relate to getting an ETH reward? Also, how does the affect getting paid so long as the same address is used? I referenced a tutorial and accidentally used .rig1 to initialize qtminer - instead of the name of my computer (I still used my wallet address). I don't understand how all of this impacts getting paid or what my options are for tweaking the configuration. I'll sort it out either way but any additional insight is appreciated. ..single Ether sent as a token of gratitude... https://etherscan.io/tx/0x9782d0cfb5f98cf086e879cc510fd45968aef3a9798ee4281b475bc569eb5c11 (Tx ID was posted) Cheers"
PM: Corporate Client: This is a real PM I received and the type of PM I will respond to if you want to work with me -
"Dear EpicEther, My name is [Real First AND Last name] and i live and study in the [Country] ( Public administration and Philosophy at [School Name] University. Me and four partners are setting up a mining company after building a succesfull mining rig containing 5 r9 280x cards. At the moment we have potential investors and a brochure containing information about ethereum and different mining set-up's with estimated costs for the inestors. I would really like to have a conversation with a veteran in the mining world and woud like to discus the following questions. - Is investing in more expensive GPU's worth it since mining will be faced out in the coming year. - How can we help to grow the ethereum network Kind regards, [Real Full Name]"

These are the type of PMs I get on a daily basis and 100% can help you with within an hours time.

New to coins, thinking about investing $500-1000.

Hey guys I recently started reading a bit about dogecoin since it seems to be blowing up and has such a cool community. I just saw a post about a guy buying $3000 worth of doge. I'm looking to possibly invest in dogecoin at $500-$1000, which I can afford. I just don't want to see a missed opportunity like with bitcoin. I have a few questions if people don't mind answering.
If I were to buy a mining rig at about $1500 3x Radeon 280x cards, what's the average doge that I could get per day with this rig? Is it better to just get a mining rig instead of investing?
I've read a post saying "first block-reward-halving is almost upon us! Its estimated to hit around 14th Feb, so if you fancy mining Doge, start now" Not sure what this means, does it mean it's harder to mine? Can someone explain it to me?
How likely would I soon see profit if I were to make the investment at this current rate? What are the risks? Should i be looking at short term or long term?
Is it a good time to buy dogecoin now? or is it dropping anytime soon then going again up in value?
Is there a site where i can buy dogecoin that doesn't require any ID like vault of satoshi, since it will take a month to get a valid photo ID. Health Card isn't valid :(
What sites should I know about and visit daily related to dogecoin?

Get my mining rig to boot, I'll pay you +$30 in bitcoin right now!

Whoever get's my mining rig to boot up and get mining properly, will be sent +$30 in bitcoin instantly from my coinbase account. I have bitcoin ready to be sent as soon as my system is up and running. Please take a look at the info below and reply with a solution! First person to fix my rig will be sent the bitcoin!
The setup:
MOBO: ASRock Fatal1ty Z87 Killer LGA 1150 Intel Z87 CPU:Intel Pentium G3220 Haswell 3.0GHz LGA 1150 PSUs: 2x EVGA SuperNOVA 1000 G2 80 PLUS GOLD Certified 1000W GPUs: 2x SAPPHIRE 11197-03-CPO Radeon HD 7970 3GB 3x GIGABYTE GV-R928XOC-3GD REV2 Radeon R9 280X 3GB Memory: 2x 4GB DDR3 1600mhz Corsair Vengence Other: 16x and 1x molex powered risers, add2psu adapter
I have three gigabyte windforce gpu's and two sapphire 7970 cards. For some reason I cannot get my rig to boot with 4 gpu's or more. I got my rig to boot into win8.1 a day ago with 4 gpu's but after restarting it, It refused to post again. I have risers on all the slots and have tried configurations with the gpu's in different slots. I have jumped the A1 and B17 pins on two of the 1x pci-e slots (last two 1x slots furthest from the cpu) and jumped the A1 and B81 pins on three 16x pci-e slots. I've tried configs with two 280x gpu's on 16x risers and with two 7970 gpu's on 1x risers. I've also tried three 280x gpu's on 16x risers and one 7970 gpu on a 1x riser. I've tried many similar configs but I have had little to no luck. Im using dual psu's with the add2psu adapter. They're the same evga 1000w psu's. All the risers are powered too. And I do receive 5 beeps as an error code through the mobo speaker when I try to boot sometimes. If not, the fans just get loud and the system never boots. All the graphics cards are plugged into the primary psu and so are all the molex cables powering the gpu risers. The second psu only has a single 24 pin cable being plugged into the add2psu adapter.
Working solutions will be rewarded! Thanks :D

Help me with my "against mining" family.

Hi guys, i'm a french boy and i need your help. Here is the translation (a bit clumsy sorry) of a petition i create. I just need people to sign it. I'm gonna show it to my mother. I hope it will be effective...
My mother still lives like she was in the 80'. A computer is an unknow noisy object which heats and disturbs the world. However i recently buy two R9 280X to mine crypto-currencies. So, you know it better my mining rig must run at night. But my lovely mom considers it's dangerous to leave such an object turned on at night. My walls will get dirty (because, yeah, a computer can blocken your walls, be careful about it). There are fire hazards (manufacturers hides it and only my mother knows it). In addition bitcoin is only a virtual thing (my mother is a great specialist in there). Indeed bitcoin are not worth more that 800$ / each. Moreover mining altcoins is easy money (YEAH SURE) and so it's against her principles. So why her son should invest his own money in such an incongruous passion ? This petition may seem strange. But it's main purpose and show that passion for computers exist. And yes, we are geeks, true geeks and we are a lot of them. And it's time to stop the parents tyranny. Because the "I'm of afraid of the unknow" start to piss me off. It's time of the democratization of computing.
I'm sorry to bother you shibes :c.

Used Hardware and warranty

About the time video cards were becoming not competitive doing Bitcoin mining, Ebay filled up with cheap second hand cards as the miners unloaded their rigs to recover some of their investment and contemplate their ASIC future. These cards had been running flatout for months and were considered pretty sketchy hardware, so they went cheap. I went looking for a bargain, and bought a 280X for $150.
Thing was, I bought an MSI, knowing that MSI supports warranty from the day of manufacture, and doesn't care who the owner was/is. Months later, running PVP WOW sessions at max quality it started bluescreening. I could run it fine if I dialed the quality back a step and frankly I couldn't tell the difference but it wasn't supposed to do that. No doubt it's prior life getting flogged as a Bitcoin slave hardened up some thermal interfaces. After verifying several times that I could induce a bluescreen at will just pushing up the settings and jumping into a 40 man PVP fight - off it went to the warranty doctor.
Today I got a new one in the mail. :o) MSI is a great company.

what brought you into the crypto world?

I was a little late to the game after Bitcoin, but managed to get in the crypto world when Bitcoin was $1000+. I mined and mined with my little processor, and didn't understand a damned thing. After some research, I felt very small in the huge world of crypto. My first mining rig was an AMD r8 280x, jsut before the Scrypt ASICs hit the market. I eventually upgrade to the dark side, and bought some GAWminer Furies (They're still running, 4x 1.3MHs). Mining isn't as profitable as it is, but I've stuck around just for the fun of it.
So, what's your story?
submitted by agentneuron to dogedcoin [link] [comments]

I'm a GPU miner, I've been in the game for over a year. I've invested over 40 thousand into GPU mining. This is why I think we will survive.

It all started back in 2013, April 17th was my official 'up and running smooth' date. I remember coming across crypto back in around February of 2013, for some reason I hadn't heard about it before then really. Bitcoin here in Canada was starting to show up in the news a bit and some friends had dabbled a bit in buying the crypto themselves.
At first I wasn't concerned with bitcoin, I barely even read about it - not knowing what use it really would have till I took the time to really read into it. Once I read into it further, I found this whole new world unravel before me. I saw a world where my fiat was worthless in a sense, the money itself was 'worth' something but the uses were limited; bitcoin and alts seemed to really allow me to express my beliefs and who I am as a person. Crypto means progress and freedom to me - fiat on the other hand means limited control by the holder of the fiat and full control for the governments/bankers, I do not own my fiat, the governments own the fiat, these bills I have are government issued and I cannot do with them as I please, to destroy them is a felony, with crypto I can do as I please, I don't have to turn it in if the government wants 'it back' because they never had it in the first place, it's no theirs, it's mine.
I had a friend who had invested $500 into bitcoin, they were cashing out in April for around $6000. A $5500 profit. They used that money to quit their job, buy a old camper van, suit the camper van up like a mobile home and live out of it now basically. They also bought a empty trailer attachment that they're building a home on so they can travel around the country doing what they love, for this individual they love music and have been in record label bands before but didn't care for it.
I thought this was amazing. I decided in march that I would buy two 7950's and start mining litecoin. I mined litecoin with the two cards and eventually did some day trading of the ltc. The day trading ended up costing me $7000 profit since my account got locked out when I sold my iphone which had the 2factor authentication app code and the app didn't transfer to my new iphone 5s that I had purchased and the 4s was reset to factory settings since I had to sell it right away to pay for some of the cost of the 5s. (side note: don't assume iTunes backs up the 2 factor authenticator apps codes!!) my trading account had a lock for a week where if I didn't login for one week the admin would take off the 2 factor authentication and allow me to sign in with just my password.
During that week litecoin skyrocketed and my coins I had from day trading plummeted. I ended up with $1700 roughly in btc instead of around $9000. However I still made enough money to pay for the power and for the two cards. I already had the cpu/ram/mobo/psu.
All in all it was a learning experience and I broke even/slight profit in a 8 month mining period.
I decided it was time to expand and go big. After having friends on the trading exchanges chat rooms, I discussed my expansion operation. Some of my crypto online buddies have gpu farms. One having 126 rigs(3 cards per rig) around 378 cards total, mostly 280x's and a few 7950's(used to all be 7950's).
my buddies stated they were not concerned with asics. For one at the time I wanted to expand, no asics were out yet, all rumors. For two, my buddies had the hashing power and had their stuff paid off. For three, we all thought that asic companies will not be able to manufacture asics cheaper than AMD/nvidia can manufacture gpu's. If anything amd/nvidia will make mining cards that work better than their current GPU's and make them explicitly for mining. The cost of ram is very high and GPU makers like amd/nvidia have the cash flow to purchase the memory chips and gpu dies. ASIC companies cannot compete with the demand that amd/nvidia have from their consumers, the manufacturing companies simply cannot tell amd/nvidia that they need to slow down shipments of chips to them because other companies like asic companies want to buy the memory for their applications. The long term ties amd/nvidia have with these manufactures means that they'll always be getting the best rates and the products first for their applications.
For forth, ASICS we thought will not be able to adapt very well to changes in the coins code that they mine. with a stroke of a keyboard, a dev can destroy the asic community.
For fifth, we thought devs on coins that are to last long term, will most likely want GPU miners to always be profitable. Seeing as ASICS become obsolete so fast(new ones every 3-5 months now days that can obliterate your old asics hashing profitability). Consumers mostly own GPU's, they'd be more willing to buy a higher end GPU even if they didn't play games a lot, just because they knew they could make the electricity bill at the least while supporting crypto and not having to worry about what would happen once GPU's become obsolete. Consumers are weary of asics, they're strange things, they're not useful for other purposes that a consumer can generally utilize(unless they are into mathematics at MIT or something and do computational stuff..)...asics just aren't practical for the every day crypto consumer.
Bitcoin is potentially totally different than scrypt in many ways. Not just algorithm based but the way its rolled out.
ASICS hit bitcoin and wiped out GPU's/cpu's, GPU's went to scrypt, scrypt started to become profitable and now has become very profitable much like bitcoin. However GPU's now have scrypt-n/jane that ASICS can't currently mine, and for the above reasons where I mentioned amd/nvidia being the kings of manufacturing, myself and other gpu farm miners don't believe that ASICS will be overthrowing GPU's entirely in the long run. If anything the scrypt coin community is going to get tired of asics and their threat to the 51% attacks and adapt the coins to be asic resistant.
I've got 46 280x's going. I run one of the most power efficient rig setups that I've ever seen in north america and I recently just expanded from a 13 card setup to 46, I'm here to stay and GPU's are here for the long run. My mining farm friends are not too concerned and they're currently mining away on ltc and wdc. I would be as well but unfortunately since my expansion I need to make some money right now to pay things off, however I am holding some wdc and ltc for the long run from previously mining on the 13 cards I had before expanding.
Don't forget that years from now btc and other alt coins will potentially be worth more in fiat. However to me, crypto is worth more than the fiat value. I own it, the government doesn't own it, and I plan to keep mining for years to come to keep supporting our networks.
Happy mining!

SHA256 with ASIC compared to Scrypt with GPU

this is the very basic for latecomer always doesn't understand.
i keep seeing they insist on mining bitcoin with SHA256 ASIC, i know its fun, its fun to see you generate money out of thin air, but thats not how we do it today because SHA256 ASIC era are gone, its very expensive playing field right now, if you insist want to mine some bitcoin, you should start mining using GPU! why?
lets calculate profitability of your SHA256 ASIC, and lets make it really easy by assuming some factor :
now go here you will see you will get 1 BTC in about 75 days right now (see the 2nd column from the rightmost), this value is not correct since it does not account for difficulty increase within 75 days, bitcoin difficulty are increasing about 35% in 2 weeks, thats about 70% per month, you will see the correct calculation is here which you will never get 1BTC within a year, and after 6 months your ASIC doesn't generate bitcoin anymore
now lets compare it to GPU miner for Scrypt mining, which i use realistic assumption here
now go here, you will see that on the most profitable coin (first row) you will get 1 bitcoin for about 30 days (its 45 days faster than SHA256 ASIC), how about difficulty increase within these period, this factor is not as scary as bitcoin, lets see difficulty chart for LTC here, you will see that the diff is up and down, by calculating the data history for 1 year, you will get that LTC difficulty increase is about 3% per month on average (this is 25x smaller than bitcoin difficulty change rate), so coinwarz data is not too much way off here by not take into account of difficulty increase
TL;DR;
note: this calculation are made in worst case scenario for GPU compared to best case scenario for bitcoin ASIC
thats just prediction and calculation, things will go wrong right? lets see the report from my own GPU mining rigs here, see 2nd sheet (RIG1-Report), this is my earning report day to day in BTC (already running since december 2013), my rigs cost about 2000$ (this is 2nd hand 6x AMD 7970 for 4.2MH/s) and will ROI within 50 days from start if my calculation are correct

Getting back into mining

Hi everybody!
Just a little back story. I started mining a while back. Back when Bitcoin had that meteoric rise to $1k+ and litecoin and dogecoin were getting extremely popular and gaining some real market shares. I was running a 4x R9 280x set back in the day in an all utility paid place. I moved that summer and electricity wasn't included so I decided to retire my rig.
I am going to move soon to an all util place again (woo-hoo!!) and wanted to get back into mining again. I'm hoping I can be provided some shortcuts into the best hashrate/$ cards out there. I was wondering how the 380x, 390, and 390x compare roughly to lets say the 280x. I've been looking around and it seems all over the place with the 390x being slightly better than the 290x.
Thanks a lot!
P.S. I'm going to do this mostly as a hobby because I find it extremely exciting but I still am wondering whats the most efficient card on the market from old habits. It's probably a lot harder now for GPU mining, but I'm not too concerned about ROI nor wear of cards.

Informative post about Feathercoin

Seeing how this Subreddit is lacking any sort of info on Feathercoins and the lack of community support we have, I have decided to start a post that would inform newbies about Feathercoin and seasoned vets on the best places to trade.
Feathercoin:
It is a Crypto Currency that was started by Peter Bushnell. It is a clone of Litecoin (This coin was inspired by Bitcoin). The Feathercoin network generates coins at a decreasing rate. It will generate about 336 million coins which is 16 times more than that of Bitcoin and 4 times more than that of Litecoin. Currently about 25 million coins have been generated.
Network hashrates, Pools, Solo mining:
Currently a mid end system comprising of 7870 or 7970 will get you abot 400 to 700 kh/s. That means that in a given day you will be mining about 7 to 13 Feathercoins on current difficulty level. However If you mine alone that is solo mining, the probability of you finding a block is hard and it may take a while before you make a coin. To counter this people have started making pools to increase the chances of finding blocks. There are many pools that allow you to have multiple workers so you can setup multiple systems and mine at your leisure. Currently some of the popular pools are:
http://www.fcpool.com/
http://give-me-coins.com/
http://www.wemineftc.com/
http://fc.ltcoin.net/
https://ftc.d2.cc/
For a full list of mining pools: http://coinpools.sdfg.org/ftc
It is highly recommended to join a pool to make mining profitable. Look at the pools posted above, look at their fee structure, their payout and make an informed decision on which pool to join.
Hardware and Mining:
Feathercoin utilizes scrypt based mining that is you can use your GPU (the Graphics card inside your system) to mine them. AMD Cards are highly recommended as they output higher hashrates as compared to Nvidia. To give you an idea of the difference a 7870 ghz edition mines at about 375 kh/s whereas a Nvidia 780ti would mine at about 224 to 300 kh/s. If you are seriously considering in investing in this venture it would be best to buy a rig that supports 6 GPU's and buy either the 7950 or the 280x as they have considerably higher hash rates and are affordable to say the least. Something one should be aware of is that mining produces a lot of heat as your system is basically running at full capacity and therefore needs a lot of cooling. People usually build rigs in the open (no case) and use household fans to cool them. Also another thing that is common is to use PCIe risers as they allow greater spacing between GPU cards and effectively help in dissipating heat. Mining uses a lot of electricity so it is best to use a schedule to mine or if electricity is cheap then 6 7950's running 24 hours a day would cost you about 12 to 18 dollars in electricity a month, maybe more depending on where you live. The software to use for mining are Cgminer (https://litecointalk.org/index.php?topic=6925.0), guiminer scrypt (http://forum.feathercoin.com/index.php?topic=961.0) and cudaminer for Nvidia cards. I would advise against Cpu mining as that is not profitable and will simply weigh you down. Invest 250 to 350 dollars in a good AMD GPU and you will be mining much more effectively.
Trading:
There are many places where one can trade Feathercoins but only a few of them offer FTC/USD exchange. Btc-e (https://btc-e.com/exchange/ftc_btc). Is one of the biggest cryptocoin trading exchanges, it does not offer USD exchange for Feathercoins as of yet but allows you to exchange for Bitcoins. Crypto-trade (https://www.crypto-trade.com/trade/ftc_btc), this trading exchange allows you to trade against the USD making it more favourable to miners however there is currently a lack of volume for FTC as of writing. Other exchanges like Cryptsy, Bter and coins-e are all good but they are heavily dependent on Bitcoins and Litecoins for now.
My thoughts
Feathercoin is fairly new and its gaining momentum, once big exchanges start listing it against the USD, the venture will become more profitable. For now it is advisable to mine as many as you can and sit on them till value improves or if you have a mining rig that is mining at 22000 kh/s (this will get you about 500 feathercoins a day) then mine the shit out of them and trade them for Btc for profit although I would recommend against this as it it reduces the value of feathercoin. Many exchanges allow you to deposit money via international wire transfers however the minimum is 2000 dollars so keep that in mind before investing real money into this venture. There are alternatives like paypal and okpay that are also accepted but not a lot of people have accounts on those so signup for a website that suits your situation.
One last ting we all need to do is spread awareness about Feathercoin, It is a miners coin and the difficulty right now makes it so much more interesting to mine. I will update this page with more information and will answer questions if any to the best of my knowledge. Happy mining

EDIT : I realized some of you might have NVIDIA GPU's and are hesitant on getting AMD. Never fear for there is a solution. If you have a motherboard that supports two or more GPU's that is you have more than one PCIe slots than follow these instructions:
If you intend to game on your system while you are mining then put the NVIDIA card in PCI slot one and buy an AMD card and put it in slot 2. Now install the drivers in the order Nvidia first reboot and then Amd second reboot. You do not need to plug in HDMI to your AMD card just leave it as it is. Now download gpu miner scrypt and select from the list your AMD card and start mining, its that easy. At night if you want to squeeze in more kh/s then run cudaminer and let it mine alongside your AMD. The best part about this is that you can be mining 24/7 on your AMD card and you will not experience any system slow down while gaming or watching movies. Remember to have atleast two workers workers created so you can mine parallel. If you already have an NVIDIA card then just install your AMD card and install AMD drivers and reboot and run guiminer scrypt. At times you might run into the issue of guiminer not starting, just delete it and re install it and it should work fine in 98% of the cases. This is for those who do not want to invest in a completely new system and would rather use their existing system. You can use cgminer as well but remember the order in cgminer starts from 0 not 1 so if NVIDIA is in slot 1 then it is -d0 -g0 and AMD will be -d1 -g1

I'm new to mining. How long will I take to break even?

With 2x 7970 & 1x 280x on my rig, how long will I take to make US$1500 (or 2 Bitcoin) worth by mining scrypt altcoins, and mining what coin?
I heard of Coinwarz but still can't figure out how to calculate my profitability.
Help!
Any rough estimation will be good to get me started. Thanks!
