Yeah, I'm assuming it has to do with the description of `CpuDfsId`, it would require an extra function to read or write to those specific bit ranges which should then...

> Would it be possible that the tool doesn't work because the frequency ID (FID) control and the voltage ID (VID) control are set to "false"? Sounds like it is,...

I'm wondering if it's an issue with the CPU using the voltage from the turbo P-state (which I'm not sure how to modify, I don't think it's mentioned in the...

I'm not sure it's been a while since I worked on this, have you tried this ? https://github.com/turionpowercontrol/tpc I think it supports bulldozer.

Possibly with this: https://github.com/cocafe/msr-utility Page 568 has info on bulldozer p-states: https://www.amd.com/system/files/TechDocs/42301_15h_Mod_00h-0Fh_BKDG.pdf#G5.3280729

I'm not sure, it's bit 63 of MSRC001_0064 according to the manual, so you'd need to read that msr, store it in a variable, then modify bit 63 to 0...

Hi @vinibali sorry for the late reply. It is possible to do the NB voltages, the reason I left it out is because the implementation is quite different between the...

Hi @vinibali, I'm currently looking at the BIOS/Kernel dev guide for 12h. If you look at the PDF: http://support.amd.com/TechDocs/41131.pdf on page 469, there is no mention of a writable field...

I found the FusionTweaker source code, I looked over it quickly, it's a large project so it's hard to to follow, but I think it's falling back on 10h numbers...

I'm looking at the amdctl code, it seems I've already implemented changing the voltage for the north bridge (-n Set north bridge voltage id (vid).), I can't see any code...
