AMD Vega mining broken on Adrenaline 18.8.1 driver

[unsivilaudio]

Using the latest drivers available, all results are returned invalid. Cpu mining works fine. Looking for confirmation I'm not going crazy here.

Basic information

• AMD A8-5800k
• XFX Vega 56 (bios flashed 64)

Compile issues

• Which OS do you use? Windows 10 Home

  add all commands you used and the full compile output here

  run cmake -LA . in the build folder and add the output here

Issue with the execution

• Do you compiled the miner by our own? Nope, using release version 2.4.7, have tried miners as far back as 2.4.3

AMD OpenCl issue

Maybe?

Stability issue

• Is the CPU or GPU overclocked? Yes, Works fine on cast-xmr.
• Is the Main memory of the CPU or GPU undervolted? No.

[BKdilse]

I'm seeing this too, just rolling back driver for now.

[unsivilaudio]

Let me know if that solves the issue, I don't have time to troubleshoot it right now.

[BKdilse]

I can confirm, rolling back to 18.5.1 drivers solves the issue.

[unsivilaudio]

Hmm...DDU'd and re-installed 18.5.1 drivers, same result. edit: deleted opencl cache files and it works again

[BKdilse]

I did same, plus removed and opencl cache, and the usual reg settings for clocking etc.

[psychocrypt]

1797 is a equal problem with the rocm driver. The new driver 18.x and

rockm using the same HSA infrastruture. IMA the OpenCL compiler is fully broken. note: I tested currently only linux.

[Spudz76]

Use old driver that worked, KEEP .openclcache and install new driver, don't change any settings in amd.txt after that, rename working .openclcache file to whatever the new one looks for (hash might change) and it will work. Broken new OpenCL compiler, not exactly broken driver, so by forcing the binaries from the old compiler into the new driver's digital butthole, it does what we want. Until the other issue irons out... or run the driver that worked and stop upgrading, it's never faster for the simple few ops we even use out of the OpenCL universe.
