So today I found out that it is very easy to have different GPU's run on different pools. Or the same pool with different workers (BTC Guild).
This allows you to monitor you GPU's more accurately, and view each GPU's performance in the charts.
Need to get cgminer or any information about it?:
CGMINER ASIC FPGA GPU overc monit fanspd RPC linux/win/osx/mip/r-pi...For this example I will use BTC Guild as a reference.
1. Creating workers in BTC Guild
We need to create atleast 2 workers. Go to the workers page and create new workers and/or rename current workers.
Mine are 5870n1, 5870n2 and 5770(installed into the same mining rig).
2. Preparing cgminer
Create folders named,
cgminergpu0 and
cgminergpu1 and soforth.
Either copy cgminer.exe into each folder.
Or I prefer to do this in Windows in each folder:
- Create batch file called
cgminer-btcguild.bat. (Does not matter what name it is, choose one that will help you identify).
- Paste the following line into it, adapt to your conditions:
"C:\Users\[YOUR USERNAME]\Downloads\cgminer.exe"
The latter will allow you to easily update/replace your cgminer.exe for all workers/pools you have configured.
3. Start your favorite texteditor and paste the following into it.
{
"pools" : [
{
"url" : "http://eu-stratum.btcguild.com:3333",
"user" : "YOURUSERNAME_5870n1",
"pass" : "123"
},
{
"url" : "http://stratum.btcguild.com:3333",
"user" : "YOURUSERNAME_5870n1",
"pass" : "123"
}
]
,
"device" : "0",
"intensity" : "12",
"vectors" : "2",
"worksize" : "256",
"kernel" : "phatk",
"lookup-gap" : "0",
"thread-concurrency" : "0",
"shaders" : "0",
"gpu-engine" : "0-960",
"gpu-fan" : "0-85",
"gpu-memclock" : "300",
"gpu-memdiff" : "0",
"gpu-powertune" : "0",
"gpu-vddc" : "0.000",
"temp-cutoff" : "95",
"temp-overheat" : "85",
"temp-target" : "75",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "1",
"gpu-threads" : "1",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}
Now change the username to the first workername. If you use a different pool, change the "url" : and "pass" : lines as well.
And leave the line
"device" : "0", as it is.
Now change the other settings apropiatly to your GPU's optimal mining conditions.
Save the text file as
cgminer.conf in the
cgminergpu0 folder.
Do this for each GPU, incrementing the setting
"device" : "0", by one for every gpu. The second GPU, the line would be
"device" : "1",Store the text file into the next folder,
cgminergpu1. And so forth.
3. Running cgminer
You can start each miner manually or create a batch/script that will start them at the same time or with an interval of X seconds.
See 2. for an example. Change out the path (optionally change the executable name to the batch file). Add new lines for each worker.
Save it as an batch script (.bat) and run it to see if it works.
4. Adjusting settings
You can adjust settings live in cgminer while running. Play around with it a little bit. Just make sure you don't do anything crazy.
Then in the main screen store the settings using S then W then enter/return key.
5. Checking workers.
In a few minutes after running you should see your workers on the BTC Guild dashboard. Showing their own MHash/s, shares, stales, etc.
Leave it running for an hour or so, and check back into BTC Guild Charts page. You now have an overview of MHash/s for each GPU. You also now can add or remove a worker in the charts.
5. Figuring this out myself and testing it has cost me time, and some downtime on mining, losing out on some precious
BTC.
