I have Intel Xeon CPU E3-1271 v3 @ 3.60 GHz and a Nvidia Quadro K620 GPU. Windows 7 SP1 OS.
xmr-stak-cpu is giving a hashrate of more than 300 H/s on the CPU.
Whereas xmr-stak-nvidia is giving hashrate of 111.5 H/s on the GPU.
With null gpu_threads_conf, the xmr-stak-nvidia miner gave me following suggestion:
"gpu_threads_conf" : [
{ "index" : 0,
"threads" : 64, "blocks" : 9,
"bfactor" : 6, "bsleep" : 25,
"affine_to_cpu" : false,
},
],
When I run the miner with this configuration, the miner crashes and following error pops: nvidia graphics driver stopped responding and has recovered
Then I tuned the parameters. Following is working: "threads" : 64, "blocks" : 6
Also, threads-32, blocks-12; threads-16, blocks-27,24 give same hashrate
and I'm getting hashrate of 111.5 H/s in the miner.
Is this expected? What can I do?
