RX 5700 XT OpenCL amdgpu-pro problem
#1
Hi everybody, not long ago I received an rx 5700 xt and so I wanted to test it but after installing amdgpu-pro with :
Code:
./amdgpu-pro-install -y --opencl=legacy,pal --headless --no-dkms
on PopOS 19.10 perfectly. I wanted to try a benchmark but... on MD5, Hashcat doesn't do anything... and when i try many times, hashcat say : CL_OUT_OF_HOST_MEMORY.

Code:
./hashcat.bin -b -O
hashcat (v5.1.0-1718-gef47811c) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

I've tested the beta and this the same problem.
(amdgpu-pro 19.50)

1. uninstall pocl, retry. there's a good chance it will work
2. uninstall amdgpu-pro, install rocm. rocm is much better

It doesn't work, unfortunately.
And for ROCm, there hasn't been any official support yet...
But i've already seen the RX 5700 XT Bench on github with amdgpu-pro 19.30 on Ubuntu 18.04.3, I know it's supposed to work

that's probably my benchmark. i installed that on a full-fat ubuntu 18.04.3 desktop image, and left all the amdgpu-pro installation stuff as the defaults, so maybe there is something going on with the flags you set (or Navi doesn't like running headless.)

If you want to stay on amd/radeon long term, it's probably better to sell your Navi card for a Radeon VII or wait for the CDNA (Arcturus) cards, as they are the ones ROCm will be supporting as they are made for compute vs. gaming. I bought the RX 5700 XT as an experiment, and ended up with Radeon VIIs instead.
