Title: `gpu-threads` Comma Separated? Post by: Osama on December 19, 2013, 01:56:07 PM Hi there,
I got two GPUs. R9 270 and R9 280x. As for R9 270, The optimal settings lead to 420 KH/s. This requires setting `--gpu-threads` to 1. If it was set to 2 the max hash won't exceed 350 KH/s. The other card, R9 280x, seems to like `--gpu-threads 2`. This leads to +720 KH/s. Again, if it was set to 1 the max hash is ~650 KH/s. As you know; CGMiner does not allow to set --gpu-threads as comma separated for each of them. So, is there any version of CGMiner allow comma separated value for gpu-threads? Is there any workaround? Title: Re: `gpu-threads` Comma Separated? Post by: Osama on December 19, 2013, 02:08:25 PM I checked the source code. It cannot be set per gpu.
I think the solution is to run two instances of cgminer. Using --device to select the right gpu. I hope this will help someone :) |
