The Best GPU for Ethereum mining for 2020 – Revenue ...

[USA-IL] [H] Sapphire RX 580 8GB [W] Paypal, ETH, Cash

** EDIT ** I AM WILLING TO TRADE 3 RX 580 for 2 NVIDIA GTX 1070, JUST PM ME.

EDIT!!! PLEASE NOTE

I'm interested in selling a few Sapphire RX 580s. The part number is 113-1E3660U-O51. All of these GPUs are currently active in a cryptocurrency mining operation. They have been in a clean environment (datacenter). They have been properly cared for and most certainly been kept in a temperature controlled environment.
In addition, they have been set to run quite frugally comparatively to the suggested settings in the wild. If you are familiar with mining I'd like to be transparent, they have been ran at 1140/2100 @ 850mV with a powertune of 2. The power consumption has been around 140W at the wall and they have not been dual mined.

WHAT YOU GET
You will get a card pre-flashed with my BIOS. So if you're interested in mining, it will mine out of the box. If you're not, flash it to stock, the stock BIOS is listed below.

What card is this exactly? These cards are Sapphire NITRO+ Radeon RX 580 8GB. These cards have a part number of 113-1E3660U-O51. The stock BIOS on these cards can be downloaded here: 256K BIOS
Have they been used to mine cryptocurrencies? Yes.
How long have the been used to mine cryptocurrencies? 6 months.
Were they bought new and are you the first owner? Yes.
What's in the box? You will get a box, most likely not the box it came in. It will not be the retail box, it will be a brown box that they were shipped to us in (from Sapphire).
What's on the card? The GPU will be flashed with my custom BIOS that is used to mine ETH at the moment. It is a power conservative BIOS that is stable at 1140/2100-2150 @ 850mV @ 28.7MH/s running sgminer-gm. You are free to flash it however you want, stock BIOS is in the first FAQ!

(Dummies Guide) How to simultaneously run multiple instances of cgminer to control different GPUs whilst using BAMT.

In cgminer you cannot specify multiple values for gpu-threads. gpu-threads is a global per-instance setting, not a per-GPU setting. If you want to run 2 different values of gpu-threads, you need to run 2 instances of cgminer.
This guide will help you if, for example; you have a rig in which one or more of your cards run better with gpu-threads set to 1 and your other cards run better with gpu-threads set to 2 (or 3 or 4)
So I'm going to assume here that you're running a rig with 4 cards and you're already set up and mining.
I'm also going to assume that you know how to use nano. So let's say your cgminer.conf has the line "gpu-threads" : "2", Unfortunately your 4th card isn't giving you the hash-rate you're expecting from it or worse, you're getting hardware errors which lead to rejected shares.
(to see if you're getting hardware errors in BAMT, you need to be able to see what cgminer is actually displaying. To do this simply SSH to your rig, log in and type "screen -r". I won't go too into this to much but where it says HW: you don't want so see anything there, if you're seeing anything other than 0 then you have problems with your config. Now to detach from this screen you need to press "ctrl+A+D" this is very important, do not press q!)
Anyway, you know that the 4th card wants to run with "gpu-threads" : "1", but you can't do "gpu-threads" : "2,2,2,1", this will not work!
So to get 2 cgminers running, follow these steps:
  1. SSH to your rig, be logged in, and a super user. You should be seeing this: [email protected]:/home/user#
  2. Type "nano /etc/bamt/cgminer.conf" Add the line: "device" : "0-2", This is saying that this instance of cgminer will be controlling GPUs 0, 1 & 2. Save and exit (ctrl+x)
  3. Type "nano startcgminer.sh" This will create a new script that you will run later to boot up your 2nd cgminer. Now type "chmod u+x startcgminer.sh" and hit enter.
  4. Add your info. below is mine but you want to replace with the settings for your 4th card (gpu 3): (where it says "device 3" this is saying that this instance of cgminer will only run gpu 3 (4th card) and "remove-disabled" makes it so it won't display the other cards)
    export DISPLAY=:0 export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export CGMINER_BIN=/opt/miners/cgminecgminer $CGMINER_BIN --scrypt \ -o miningpoolserver.com:3333 -u username -p password \ -o backupminingpoolserver:3333 -u username -p password \ -I 20 \ -w 512 \ --gpu-threads 1 \ --thread-concurrency 32765 \ --gpu-engine 990 \ --gpu-memclock 1500 \ --gpu-powertune 11 \ --gpu-vddc 1.025 \ --device 3 \ --remove-disabled \ --temp-cutoff 99 \ --temp-overheat 95 \ --temp-target 85 \ --auto-fan \ --gpu-fan 50-85 
    Note: Make sure there are no random spaces at the end of any of these lines and also make sure that the I for intensity is upper case.
    Now save and exit the script by hitting ctrl+x etc.
  5. type "screen -ls" and hit enter, you should see something similar to this:
    There are screens on: 4366.pts-1.bamt-miner (12/30/2013 08:00:56 PM) (Detached) 1 Sockets in /varun/screen/S-root. 
    So this is saying that there is currently only 1 screen running and BAMT is using it to run cgminer inside.
  6. Type "screen" and hit enter, it will come up with a load of text about screen, just ignore that and hit enter again. Now you are inside your new 2nd screen.
  7. Now type ./startcgminer.sh You should now see cgminer boot up and start mining with just gpu 3. To detach from this screen you need to hit ctrl+a+d.
And that's it, there should now be 2 screens running.
To check the other screen type "screen -ls" and hit enter, you should now see both screens running. Something like this:
There are screens on: 6349.cgminer (12/30/2013 08:08:35 PM) (Detached) 4366.pts-1.bamt-miner (12/30/2013 08:00:56 PM) (Detached) 2 Sockets in /varun/screen/S-root. 
To look at one screen type "screen -r 6349", to look at the other type "screen -r 4366" (remember to detach from screens using ctrl+a+d)
You should still be able to see info for the first 3 cards on BAMT's web UI and in fact I can still see the temp and load for my 4th card.
Please feel free to leave feedback, or let me know if I've missed anything.
I hope you found this guide useful and if you did please consider a small BTC donation :)

Help with a Gigabyte GV-R928XOC-3GD REV2

So, I'm running a fresh install of CentOS 6.5 x64. I'm attempting to get everything working up to the maximum potential. I have started by following the following guide very closely:
http://truemetal.org/universe/blog/2013/05/howto-cgminer-bitcoin-litecoin-etc-amd-driver-install-on-centos/
Sadly, everything works, but I seem to be stymied by a less than ideal hash rate of around 590 - 610 Khash/sec. I have started with the recommended settings on the Mining Hardware comparison. According to that site, I should be getting ~720 Khash/sec.
Here is my current command line:
cgminer --scrypt -o stratum+tcp://poolurl.com:3334 -u username -p password --gpu-powertune 20 --thread-concurrency 22272 -w 256 -I 13 -g 2 -d 1
I determined thread-concurency by running cgminer with no tuning options and pulling the value from the .bin file.
I have also tried various combinations of adjusting thread-concurrency, intensity ( -I 18, -I 20, -I 12, -I 13 ), GPU threads ( -g 1 or -g 2 ), adjusting work size between 512 and 256, and either manually specifying --gpu-engine and --gpu-memclock, or choosing --auto-gpu.
Sadly, nothing gets me much above 600 Khash on this. :(

iwtwe's Total Noob Starting Guide. much noob..such help...very inform...wow

NOTE for seasoned miners, if I have made a mistake or if there is an easier way of configuring the miners or if I left something out, please do not hesitate to contact me about it so that I can edit this post accordingly. Let's help new people out so that the community will continue to grow! many thanks...wow
Hey you. Yes you with the eyes. Are you new to the world of crypto coin mining? Have no idea what a dogecoin is? Want to start mining dogecoins today and just can't seem to figure it out or get it to work?
Well have I got much help for you! About a week ago, I finally started mining after two painful days of trying to get it to work. Basically, I was a total noob and didn't really understand anything about mining in general. Because of the joy mining has brought me so far I am writing this guide to hopefully help out new members or other total noobs.
It's safe to say I've been bitten by the dogecoin bug. I started out with a measly 50 khash/sec and made approximately 10 coins in 12 hours. * My reaction when I finally got my miner to work * Reaction cont.
Now I'm up to 500 khash/sec after figuring out all the 'nuts and bolts' of mining. wow...such optimization...many hash
I'll break this guide down into three categories: Detailed Info, CGMiner Config for AMD Cards, and lastly, CUDAMiner for Nvidia cards.
Detailed Info very words....wow
A dogecoin is a type of crypto currency that is traded against bitcoins in a crypto currency marketplace.
You can earn dogecoins by contributing hashes (computing power) to a mining pool to help find a block.
There are a certain amount of dogecoins that will be released. These coins are released in the form of a block ranging in quantity of 1-1,000,000 doge coins. It is worth noting that the total quantity of coins per block will soon be halved to just 500,000.
Things you will need to mine: * dogecoin wallet * computer with a GPU * an account with a mining pool * a worker for the mining pool * mining software
1) [http://dogecoin.com](Download the doge coin wallet and install it)
2) Turn off your computer's anti-virus software and allow the dogecoin wallet through your fire wall. *VERY IMPORTANT
3) Run the dogecoin wallet and let it sync with the network. It is important to note that this can take a short amount of time or even up to 12 hours to complete. Just be patient. Use that time to research mining more.

Once your wallet has synced with the network, it is time to sign up with a mining pool. Think of a mining pool as a virtual supercomputer that is made up of many smaller computers connected together. This pool or 'super computer' allows for greater processing power. More processing power = greater chance of the pool finding a block.

Finding a pool
"Dear shibes!
Be careful when running Java and/or entering the usepass on sites. There are phishing sites out there that imitate other pools to steal your data.
When accessing a mining pool, DO NOT follow any redirects, always access the site directly and check the URL. For extra security, make sure you're using https://
Don't run Java!" <--- not my words, but very good warning to take into consideration
1) Perform a quick google search or use the links in the side bar to find a pool!
2) For this example I will be using https://fast-pool.com/index.php (I in no way, shape, or form endorse this particular pool. It was the first one I clicked. Feel free to use any pool you want, as the sites are all the same.)
3) You're going to want to click "Sign Up" in the menu on the left of the page. After clicking, sign up for an account.
4) After signing up for an account, log into your account. (For the sake of my example my mining pool site username will be "Shibe")
5) Now we will create a pool worker. Click "My Workers" in the menu on the left side of the page.
6) Choose a worker name and worker password and click submit. *NOTE THE WORKER NAME IS NOT THE SAME AS YOUR ACCOUNT USERNAME
7) For the sake of the example my workers name is "worker1" and the password is "x". *Note capitalization matters so don't forget it.
Now we will download a mining software and configure it to mine.
Before we do that I want to clarify what the info we will be using to configure our miner is.
1) Click "Getting Started"
In my example pool under getting started you will see this in "Step 3":
  1. Configure your miner.
    Settings for Stratum (recommended): STRATUM: stratum+tcp://fast-pool.com PORT: 3336 Username: Weblogin.Worker Password: Worker Password
If you use a command-line miner, type:
./cgminer --scrypt -o stratum+tcp://fast-pool.com:3336 -u Weblogin.Worker -p Worker password
The above explained:
Final Step Regarding Mining Pools
We need to add our payment address to our mining pool account so that we can receive the dogecoins we help mine.
1) Click "Edit Account" on the menu on the left side of the page.
2) Scroll down until you see "PAYMENT ADDRESS".
3) Minimize the webpage and go to your doge coin wallet.
4) In your dogecoin wallet click the "Much Receive" tab.
5) You will see the Label "Default" with an "Address" composed of a long random string of letters and numbers.
6) Right-click that string of random numbers and letters and select "copy address".
7) Maximize the pools webpage again and paste that address into "PAYMENT ADDRESS".
8) Enter you pin and click "Update Account".
WE'RE NOW READY TO DOWNLOAD A MINER such hooray....many celebrate
IF YOU HAVE AN AMD CARD, THIS SECTION IS FOR YOU!
*Note AMD cards are much better for mining than Nvidia. It's just the way it is!
We will be using cgminer to mine dogecoins with our AMD cards.
While there are newer versions of cgminer avaliable you're going to want to download cgminer version 3.7.2 because any higher versions do not support GPU mining.
1) Make sure your AMD drivers are up to date.
2) This version of cgminer is now only available on gitub at this url. The option to download the zip file in on the bottom left right side column.
3) After downloading the file, extract its contents to a folder on your desktop.
4) Before we do that go to Control Panel Folder Options View select "Show hidden files, folders, and drives" and click apply.
BEFORE YOU TRY THE BELOW, RUN THE APPLICATION AND INPUT THE SERVER URL:PORT (stratum+tcp://fast-pool.com:3336) "enter" USERNAME (Shibe.worker1) "enter" and PASSWORD (x) "enter".
*If the application runs without giving you errors hit the [S] and select "create config file" and hit enter.
5) If that didn't work, we will make a .conf file that allows cgminer to run correctly.
6) Now go to the folder you extracted cgminer into.
7) Right-click anywhere in the folder and select "New" Text document.
8) Right-click the new text document you just created and select "Edit".
9) Copy and paste the following into that new text document leaving no space at the top and enter the appropriate pool information accordingly. Noticed I used my STRATUM info from my example.
IF YOU HAVE ONLY ONE GPU USE THE BELOW

Whats wrong/right with my rig? 4x7950

Hello everybody,
I've been using bitcoins for a while now but just starting to learn about mining.
My setup is: 4x7950 Gigabyte 3GD
Seasonic X-1250
ASRock MB-970EX4
AMD Sempron 145
4 GB Corsair DDR3
3x powered 16x to 16x risers 1x powered 1x to 16x riser
Windows 7 64x
cgminer 3.1.0
cgminer.exe -o http://127.0.0.1:9322 -u user -p password --thread-concurrency 21712 -w 256 -I 18 --lookup-gap 2 -g 1 --gpu-powertune 20
Here is the funny part, I am getting amazing hash rate with only 3x 7950's. http://oi40.tinypic.com/10dzinr.jpg
Compared to 4x 7950: http://oi42.tinypic.com/2wr26he.jpg
Why is this happening? How can I achieve same hash rate with 4 gpus?

[modpost] Possible wiki page, something I call "All about miners," covering things from basic terminology to miner config files and overclocking.

What is a miner?
A miner is a computer set up to solve cryptographic hashes in the litecoin network. Once a clump of these hashes, or a block, is mined, litecoins pop out! It's like opening a box of chocolates, except you know what you're gonna get :) Miners also handle transaction confirmations, making sure no single coin is double-spent.
Setting up your computer to be a miner
What kind of computer do I need?
Optimally, you'd have a good power supply and a couple decent Radeon/ATI/AMD graphics cards. Because of litecoin's hash algorithm, the gap between mining with graphics cards and processors is less than with most other cryptocurrencies, meaning that mining with some desktop processors may be worth it after electricity costs. Note that mining with laptops is not recommended because of the heat generated by mining, and mining with NVIDIA graphics cards may not be worth the cost.
How do I know if litecoin mining will be profitable for me?
First, check how fast you'll be mining with your hardware, how many litecoins you'll mine in a day, and how much litecoins are worth. Now, multiply the number of litecoins per day by their worth. Then, find out the power draw of your hardware, and calculate energy cost. Then finish by subtract energy cost from your daily earnings. If your number is positive, you're making that much money per day. If negative, you're losing money.
Keep in mind that the worth of litecoins goes up/down, and you have to earn the cost of your hardware before you churn a profit. Mining difficulty also goes up/down, depending on how many people are mining how fast in relation to how many litecoins are supposed to be generated how fast. See the economics(coming soon) post for more info.
Okay, I did all that. How do I start?
All you have to do is download a program and change some settings (later in the guide), and you're ready to go. If you're comfortable with configurations and the command line, Reaper and cgminer are your best friends. Otherwise, GUIMiner-scrypt is right for you. If you want to mine on your processor, download the "batteries included" miner via this link and setup should be relatively self-explanatory.
Do I mine alone?
Due to the difficulty of mining, we recommend that you mine with a pool where multiple people mine together. Visit your pool's about or help page for proper miner settings, which we're about to get to in-depth!
Under the hood
Configuring your miner (aka the hard part)
Before we get started, you should become familiar with these terms:
None of those will have any affect on how fast you mine. The settings that we'll be focusing on are:
If you're using GUIMiner-scrypt, there are default settings for different cards (lower right dropdown). I'm mining on a 7870. Here is what it looks like for me. You can follow along with the rest of this guide to optimize your settings. GUIMiner-scrypt is just a GUI to cgminer and reaper anyways.
If you are using a command-line miner, like reaper and cgminer, I recommend you download and isntall Notepad++ or SublimeText if on Linux.
Reaper is currently considered to be the best tool for mining. After you unzip your downloaded file, in the folder you'll find reaper.conf. It should look something like this:
kernel reaper.cl save_binaries yes enable_graceful_shutdown no long_polling yes platform 0 device 0 #mine bitcoin mine litecoin #mine solidcoin 
This will make it mine litecoin on your first graphics card and reference litecoin.conf, which for me looks like
host us-pool.give-me-ltc.com port 8080 user poolusername.1 pass anything protocol litecoin worksize 256 vectors 1 aggression 18 threads_per_gpu 1 sharethreads 32 lookup_gap 2 gpu_thread_concurrency 15380 
As you see, my thread concurrency is slightly different from the default of GUIMiner-scrypt. I found that this concurrency gives me the best hashrate!
NOTE: I do not use cgminer to mine litecoin. If you plan on using cgminer, which offers more hardware-controlling settings, in the cgminer folder you will want to create a text file. Then, open that text file w/ Notepad++ or SublimeText, then Save As > cgminer.con > file type > all. This will save the file with the proper name and as the proper type. Note that cgminer does not support high concurrencies. For me, cgminer.conf would look something like:
{ "pools" : [ { "url" : "XXX", "user" : "XXX", "pass" : "XXX" } ], "auto-fan" : true, "gpu-engine" : "920", "gpu-fan" : "0-100", "gpu-memclock" : "1375", "gpu-powertune" : "20", "gpu-vddc" : "1.219", "temp-cutoff" : "85", "temp-overheat" : "80", "temp-target" : "75", "temp-hysteresis" : "3", "kernel" : "scrypt", "gputhreads" : "1", "thread_concurrency": "8192", "worksize": "256", "intensity" : "dynamic", "vectors" : "1" } 
You saw some settings similar to what we saw in Reaper's litecoin.conf. The other settings have to do with my card's clocks, voltage, and fan. This is covered in the overclocking section right below!
Overclocking (aka the risky part)
Okay, first off I'm not responsible if you cause damage to your parts. Please research safe overclock settings for your card. Second, don't be afraid. Modern hardware has many safety features in place that help prevent mayhem like me...lol jk this isn't a car insurance add. For your better understanding, become familiar with these terms:
No one setting controls how effectively you mine; what matters most when it comes to clocks is the ratio between your core/memory clocks. Generally, a ratio of 0.7 or below is best. You will need to experiment. If you're using cgminer, you can control card settings from the conf file. However, if you aren't, I recommend using MSI Afterburner as your overclocking tool. You will need to unlock some settings. Using my cgminer settings, MSI Afterburner looks like this. I have found these settings to be the most stable while bringing me a high hashrate.
Other people's optimum settings
You can check the sidebar for the hardware comparison chart, but it is rarely updated and has huge sways in results. It is a good starting place. The mods of this subreddit will be putting together an updated, more accurate list in the near future.

Setup Help

I have been mining DOGE with two R9 270s on BAMT but I want to try out multi mining. I'm assuming the only thing I need to change in my config file is the pool. Here's what I have:
{ "pools" : [ { "url" : "stratum+tcp://useast.wafflepool.com:3333", "user" : "my bitcoin adress", "pass" : "x" } ] , "intensity" : "19", "vectors" : "1", "worksize" : "256", "kernel" : "scrypt", "lookup-gap" : "2", "thread-concurrency" : "24000", "shaders" : "0", "api-port" : "4028", "expiry" : "120", "gpu-dyninterval" : "7", "gpu-platform" : "0", "gpu-threads" : "1", "gpu-engine" : "1150", "gpu-memclock" : "1500", "gpu-powertune" : "20", "log" : "5", "no-pool-disable" : true, "queue" : "1", "scan-time" : "30", "scrypt" : true, "shares" : "0", "no-submit-stale" : true, "kernel-path" : "/uslocal/bin", "auto-fan" : true, "auto-gpu" : true, "temp-target" : "70", "temp-cutoff" : "77", "temp-overheat" : "90" }
However, when I fire up sgminer, it freezes at "waiting for work to be available from pools" for a little bit and then just terminates. What am I doing wrong here?

7970 mining at a good speed, but i'm not seeing alot of accepted shares

I moved all of my bitcoin miners over to litecoin when my bfl rigs came in. The 7970 is mining at just under 700, but i'm not seeing a lot of accepted shares. This is what I see
I'm using these flags: cgminer --scrypt -o http://p2pool.org:9327 -u xxx -p xxx -I 13 -g 2 -w 256 --thread-concurrency 8192 --gpu-powertune 20
Is this normal? Coming from btc i'm used to seeing a long pour of accepted shares with a splash of work update requests.
Side question: I used to be able to force a framerate on the gpu when mining btc, can I do that with cgminer? I can't even use my mining rig unless i'm RDP'd into it and use the rdp vid drivers.
EDIT: p2pool was my problem, i switched to hashfaster and am doing much better.

Hey /r/BAMT, I'm having trouble running 6 290x GPUs but no problems running four. Any advice?

Our machine can hash at 900+ khash when we have four GPUs running. When we try to run 6, the screen either freezes or turns black. Also, when we hard restart (pushing the reset button), only 5 GPUs show up. We have to switch off the machine for BAMT to recognize all 6 GPUs again.
My specs: // BAMT 1.6 // 6 MSI R9 290x's // 2 1200W Raidmax PSUs with a Add2Psu adapter // Asrock Bitcoin Pro H81 Motherboard
Settings that work well with our 4 GPUs but crash 6:
"auto-fan": false, "gpu-fan": "100", "temp-cutoff": "100", "temp-overheat": "98", "temp-target": "90", "worksize": "256", "xintensity": "93", "thread-concurrency": "32765", "gpu-engine": "950", "gpu-memclock": "1425", "gpu-powertune": "20", "gpu-thread": "1", "api-port": "4028", "api-listen": true, "api-allow": "W:127.0.0.1", "failover-only" : true, "no-pool-disable": true, "no-submit-stale" : true, "queue": "0", "scrypt" : true, "kernel-path": "/uslocal/bin" 
Do you think this might be a software or power issue? We are using powered PCI Risers.
Let us know if there if any more information we could provide. Any feedback would be greatly appreciated.
