I have a factory-overclocked Radeon 270x “Pitcairn” (Southern Islands) running on Manjaro 5.15 RT, with the amdgpu driver (experimental support).
Problem is it crashes after a while under load. To be expected, since it’s such an old chip. From my investigation it’s not a temperature but rather a hardware problem that people have experienced and discussed on the Arch and Gentoo forums, on Phoronix, Git, Reddit, etc. The solution seems to be to slightly undervolt/underclock the card, in order not to push it to the point of crashing. On Windows this is a non-issue because the Catalyst driver allows you to customize voltages & clocks.
On Linux, however, it seems this chip does not expose the necessary settings for that, and does not allow fine-tuning of voltages and clocks, even with the necessary option (amdgpu.ppfeaturemask=0xffffffff) enabled, maybe due to the fact that support is only “experimental”.
In CoreCtrl software, I can only set fan curves and toggle between “do not control”, “automatic” and “fixed” (1. high or 2. low) power profiles. And the card only reports the following information:
Fan speed
Used memory
Temperature
GPU & Memory clocks.
I would just like to remove the factory overclock, ie. reduce the GPU & memory clocks by 100mhz. But no matter how I mess with the settings (short of flashing anoter vbios, which I don’t know how to do) I cannot achieve this.
Of course, I could just buy a newer card and be done with it. But I like the idea that Gnu+Linux allows you to give old hardware a second life, and I don’t really need to extract more performance out of the hardware, just to prevent it from crashing.
Here’s a log for reference:

I’d be real thankful if someone could provide their input on the issue.
Cheers!
