Hi all,
I’m having a hard time finding debug information about this #mining issue on Google, so hopeful some folks here will know what to do.
TLDR – I have a 6 x GTX 1070 rig that I’m using to mine equihash. 4 of the GPUs run in perf level P2, the other 2 run in perf level P8. The former get 30 Sol/s each. The latter get 5 Sol/s each.
Here’s what my perf looks like if I run it on GPU #0:
./nheqminer_cuda_tromp -l equihash.eu.nicehash.com:3357 -u 1Kj1d2vFfCNfy2coNENxnUEQRPTsbHicen.worker1 -t 0 -cd 0
[08:19:42][0x00007f64913e9740] Speed [300 sec]: 15.0287 I/s, 29.3621 Sols
Here’s what my perf looks like if I run it on GPU #1:
./nheqminer_cuda_tromp -l equihash.eu.nicehash.com:3357 -u 1Kj1d2vFfCNfy2coNENxnUEQRPTsbHicen.worker1 -t 0 -cd 0
[08:22:41][0x00007f919c592740] Speed [300 sec]: 2.89559 I/s, 5.49345 Sols/s
Here’s what my perf looks like if I run it on all GPUs:
./nheqminer_cuda_tromp -l equihash.eu.nicehash.com:3357 -u 1Kj1d2vFfCNfy2coNENxnUEQRPTsbHicen.worker1 -t 0 -cd 0 1 2 3 4 5
[0x00007fee8b5d0740] Speed [300 sec]: 64.0553 I/s, 124.01 Sols/s
Here’s what nvidia-smi looks like:

Any ideas? How can I get the 2nd GPU the 5th GPU to be in perf state P2?
