580 with ppt?, isn't that only vega support ppt? how to set 580's ppt?
All AMD GPUs since some time use PPT - I was setting them for my old HD7950 when I was still mining w/ it.
Process is exactly the same as for Vega. Create one using ODNT (or download one if you're feeling lazy and don't mind applying mystery settings to your GPUs), then just double click the reg file. I'm assuming you're talking Windows - the Linux process is a little more involved.
Btw, PPT was required for vega early on, because you couldn't properly undervolt w/o it. Same was not true for polaris, so using PPTs is more of a process choice (unless being used for more 'under the hood' things like modifying fan tables)
Very interesting. Could you tell us more about what PPT and ODNT are? I am very concerned about the energy efficiency of my RX488 ..
And how did you manage to raise the memory frequencies so high, with such a low voltage, the memory probably gives a lot of errors in this mode? My RX488 works 1100/2025 @ 855 and gives 30.5hash .. above, I cannot raise the memory frequency at such a voltage that the card would work without memory errors (HWinfo).
How can I do the same in the windows?
