Question Asus Strix Vega 64 Undervolting Question


Jan 23, 2019
I've been applying undervoltage to my Asus Strix Vega 64 card for a few days. But I haven't found stable values. I think I'm misusing the process. I didn't get that.

  1. I enter the wattman settings when the card is in a balanced profile.
  2. I turn off the Chill feature.
  3. I set the card to manual settings.
  4. I make the power limit + 50%.
  5. I am dropping P7 value from 1200 to 1100.
  6. I reduce the P6 value from 1150 to 1050.
  7. Set the HBM Memory Value to the same as P6 (1050).
  8. I then do the Valley test and the Tomb Raider Benchmark test.
  9. Up to this point no problem.
  10. Then I continue to reduce P7 and P6 values.
  11. I draw the memory value of HBM to the same level as P6.
  12. I'm P6 and HBM Reduce memory to 1000Mv. When I lower the value of P7 to 1060Mv, the card crashes. Can't pass the test.
Can you help me?

I've been writing in forums for a few days but couldn't figure out this problem. I don't want to overclock my card. I just want to reduce the voltage and reduce the temperature as much as possible.


Please share you P state and HBM2 frequencies as well. Voltage is only half the equation

100mV is a pretty average amount of undervolting for a given P state.

Have you graphed your frequency vs voltage curve?

Have you tried BIOS 2 - Power Save profile to see what that gives you? From what I've seen, that's pretty close to what you can achieve manually.

Rob is right though. At some point, all GPUs hit their undervolting limits at a given frequency. And there's a given range of variability based on chip lottery. What makes you think your card has more room to go?
