Well like I say it's crashing after 5 minutes and I can't use the ROCm kernel anyway (or amdgpu-pro driver either because I'm using Debian now but apparently you don't need that).
When you say it's 0.5Mh/s below Windows do you mean with or without the dag fix?
even with DAG fix the hashrates I get is 0.4-0.5 lower on same card same clocks on win 10.
Finally got it working. All my problems were because of the Pitcairn card being in the system. When I use the radeon driver then it won't mine at all, because it says DRM version is 2.50, even though I'm only trying to mine on the 570. When I use the amdgpu driver for the 270 I can mine...but the dag fix doesn't work.
Now after taking that card out of the system I'm getting 28.4MH/s @ 1140/2030 on a 4GB AJR card using Claymore. Haven't tested the same settings in Windows yet but it looks like it should be on par. Now I just gotta try different miners to see what's fastest and optimize the BIOS for each individual card, but the path to Linux rigs is clear now.
Hi everyone,
I have problems to undervolt memory and core voltages.
Usually I mine with claymore at 0.85v (stable) with the commands -mvddc -cvddc and all is good, but I want to try nicehash.
So, I own rx 580 8gb;
I cannot undervolt with msi afterburner, memory voltage is locked for amd cards I read...I can only set core voltage but it's not enough to get me to 0.85v that I can reach with claymore.
I cannot undervolt with nicehash, it says failed to modify voltage.
I read editing voltages with polaris bios editor has no effect, I also tried to set 850 and it does not work.
How can I reach 0.85v or undervolting memory (and also core) in general, please?
Is the only option left to edit bios with hex editor? Am I missing something?
Thanks
Happy mining
Are you using the latest stable afterburner 4.4.0? It should work with the latest drivers and allow up to -200mV. Does for me anyway. Make sure you apply the BIOS signature check patch if you're running a modified BIOS (which you should be doing unless you just don't want a free +7 or more MH/s).
Undervolting the memory controller is not really worth doing. Keep it between 950 and 1000 for stability. You can just set that in the BIOS and forget it.
