Those tools apply an offset that is active for each dpm state. You might be stable in dpm7 but crash in a lower state with this offset. That's basically why we do mod our BIOS for undervolting. We have no WattMan (yet?) for those cards that could set a fixed voltage on each state.

Ok tnx, as far I can see WattMan is only released for 480....

I presume my solution would be to change only P7 voltage state
post #2953 of 3751
you can set custom fixed voltage for each state even without wattman

also AMD really piss me now as they fixed not really problematic power draw from PCI-E in 3 days but fixing 2D power usage with multiple monitors / 144hz monitors / playing video took them 3 years without any success....

its really simple thing to fix this issue just make application profiles to use higher values if 2 apps are running together...

It'll throttle back the card if it reaches/exceeds the max temp. So if you set the temp lower, it'll throttle at a lower temperature. If you set it higher . . . eh I don't recommend that.

No idea, as no one replied, IMO you will need someone like The Stilt, who has better hardware knowledge to give you insight.

Odd question but can we disable shaders?
post #2958 of 3751
yep you can disable shaders but its little complicated use bios from 290 then change mask for disabled CU units

I am already using 290 bios on the 290x to disable 256 shaders, but I would like to test disabling even more shaders.

Is there a tutorial somewhere?


thanks
post #2960 of 3751
no there is no tutorial but you need to change mask in command table just check with atomdis how locked vs unlocked tables look like
