XMR-STAK-AMD [GPU COMPUTE ERROR]

Open ejazskp opened this issue 8 years ago • 1 comments

Chaps, I am using xmr-stak-amd on Windows 10 x64 built with CMAKE and VS 2017 Community. OpenCL used in CMAKE is from AMD APP SDK. All remaining CMAKE build is using xmr-stak-dep.

Single Vega 56 (out of the box. no Vega 64 BIOS flashing) with the following config... "gpu_thread_num" : 2,

"gpu_threads_conf" : [ { "index" : 0, "intensity" : 2016, "worksize" : 8, "affine_to_cpu" : false }, { "index" : 0, "intensity" : 1600, "worksize" : 8, "affine_to_cpu" : false }, ],

"platform_index" : 1,

The AMD driver is latest blockchain.

GPU settings are... HBCC disabled Wattman - GPU frequency -30% Wattman - Memory frequency -50MHz Wattman - Power limit % -20

Hash starts at around 1880/s but then eventully settles at around 1600/s.

Question 1, What does these error mean? Question 2, How to rectify them? Question 3, Is it impacting my mining effort/results?

Why do I ask question3? Look at the logs below. At 10:30:19, pool accepts the results and then by 10:32:11 I get 5 "GPU COMPUTE ERROR"s then the pool accepts the results again by 10:44:10. I have also seen that pool accepts my results just before this error and then 2 minutes after as well. So based on timings I am thinking if this error is non impacting?

The log just before and after the error is... [2017-11-19 10:29:59] : Result accepted by the pool. [2017-11-19 10:30:19] : Result accepted by the pool. [2017-11-19 10:30:35] : Difficulty changed.

So results accepts by the pool at 10:49:22 when the last error was at 10:47:57.

Every bit of help is appreciated!
