Recommended driver and kernel versions? #3

Closed nioroso-x3 closed 6 years ago

Hi, I was testing this miner and it only gets up to 1200 hash/s, using 16 threads 224 blocks. Im using the ROCM packages for ubuntu 16.04 with kernel 4.15 on a vega 56. What driver version hits 1800+?

If you are on 4.15, you must also install amdgpu-pro 18.30 with --opencl=pal --headless and use its dkms module. Do not use rock-dkms module. I’ve also shortly detailed that here: https://github.com/949f45ac/xmrig-HIP#415-or-older-kernel-and-amdgpu-pro-and-rocm To hit 1800+ you need overclock as well. If you don’t know how that works, head over here: https://github.com/RadeonOpenCompute/ROCm/issues/463 And use soft pp table approach, the other stuff does not really work. Soft pp tables work on kernel 4.15, no problem.

Ah, nice, I have other machines running with 1800+, but using the 18.10 driver to compile the kernels and 18.30 to run. I thought rocm wouldnt run with the amdgpu-pro dkms driver. Thanks!

Afaik you do not need to use old compilers anymore; the xmr-stak devs found a way to work around the bug in the latest version. (Now the OpenCL miner runs faster for me than this HIP miner, except on RX 570.)
