I switched to gdpool and got the x11 mod sgminer 4.1.0 working on one of my miner computers. A single 280X at intensity 15 and 1100/1500 is giving me 2.99 Mhash. IfI try to use intensity 19 it keeps failing the graphics driver and resetting. This is my first time working in a config file with the multiple short lines of text and all the brackets and braces, I have always used notepad config files with the
-I 19 --thread-concurrency 8192 --gpu-engine 1100 --gpu-memclock 1500 --auto-fan --temp-target 70 --temp-overheat 82
style of coding.
I do have a few questions, though. This gdpool doesn't exactly provide an overabundance of information and details. How do I set up individual workers? Do I even have to? Or does each mining PC get the same details in its config file, and each one just pays out to the same wallet?
How do I set payout intervals, like payout every 1 GDN or 10 GDN or 100 GDN? I keep my wallet on my main PC, and getting notified every few minutes that I just got a fragment of a cent of GDN will get annoying fast.
I'll play with it on one PC for a day or two, then put it on the other PCs as well. I'm uncertain how to handle different GPU types with this style of config file, how am I supposed to know that both the computer and I think GPU 1 is the same GPU? Which is GPU2, 4, 5, etc? Right now one of my miners has a single 280X, another has a pair of 270X's, and the third has 2 7950s and 3 270X's. I guess I could swap the pair of 7950s and 270X's if I had to.
In regards to GDPool.org:
GDPool.org is run using the NOMP pool software and requires you only to put your GDN address as your username. Each individual worker/miner can be setup with the same information. However, you could generate multiple GDN addresses and assign each worker to a different one if you wanted to somehow track individual payouts. The payout on GDPool.org is set to payout whenever your balance reaches 1 GDN or higher. Depending on your hashrate, this will probably result in many small payments (you cannot modify your payout amount/interval).
In regards to sgminer:
I use the following options/flags for sgminer. To control what GPU's you use, you can see the --device 0,1 part tells sgminer to use my first and second GPU's. These are normally orderd from 0 to x, where 0 is closest to your CPU. Since i specify multiple GPU units, I can append a coma to separate the individual settings for each GPU. Your miner is probably failing because of the thread-concurrency setting your using. You will probably have to play around with it for a while.
sgminer -k x11mod -o stratum+tcp://gdpool.org:3032 -u ADDRESSHERE -p ANYTHING --device 0,1 --gpu-memclock 1500,1500 --gpu-engine 1160,1160 -g 1,1 -w 256,256 --intensity 21,21 --no-submit-stale --auto-fan --temp-target 79 --temp-cutoff 90
Hope this helps! Good luck!
