RX460 poor hash rate and multiple compute errors, any ideas?

[aedelgod]

Hi all,

Would like to know if anyone has some ideas and could point me in the right direction of my current issues. Kernel: 4.20 on Ubuntu 18.04 LTS amdgpu-pro-18.20-673703-ubuntu-18.04 w/ --opencl-legacy install for RX460 2GB XMRIG-AMD 2.8.6-Xenial x64 binary

I was CPU mining but decided to stop to get better CPU performance for my actual workloads.

Thank you to anyone taking the time to help me out with this, I'd really like to know what I'm doing wrong or if it's a driver bug.

Driver, in case you never figured it out. Downgrade to 18.10 (and clear out your opencl cache) and it will work.

Hey @unsivilaudio I did confirm that and appreciate your comment. I haven't actually rolled back the drivers to that version yet but it is 100% the problem.
