Do you mind exporting and uploading your bios? I also got mine from AMD's store February 18th.

Anyways...still good voltage

Edit: @CarbonFire
These are "defaults", power set to minus 20, RPM set to maximum - rest is automatic.

Stress test settings:
MSI Kombustor - 1920x1080

Stress generation is Power Capped.
Ambient Temps: 21°C

IF temps on -20 settings even reach throttling temperatures in scenario above, the cooler would be inadequate. The goal should be to reach similar temperatures on Power +-0%.

This indicates that stock cooler is actually quite good, however it needs to be lapped and used with proper paste. This is fresh Arctic Silver 5, i applied it about an hour ago so it will need 2 more weeks to cure.
Yep, spoke too soon. Elite: Dangerous works fine at that voltage, but I threw on some Far Cry 5 and crashed after about 45 minutes. So far FC5 has not crashed at 932 mV.

Yeah, if I can get some answers - What's weird about my default undervolt default setting? That's it's so low? Did I hit the silicon lottery here?

Thanks

No clue until you actually undervolt or try to overclock it. Mine is stable at 1060mV 1800Mhz when I undervolt from my default 1135mV. Anything under isnt stable but it runs stable at 1950Mhz @ 1070mV.

How did you set the fan speed so high?

Set the fan to manual and set the fan curve to 3850 RPM.

To the guys talking about the stock voltage, each chip is binned differently. You can check out this Google Docs sheet where people list their defaults. https://docs.google.com/spreadsheets...-Gk/edit#gid=0

Thanks, looking at that chart my Radeon VII seems pretty decent at it's 150Mhz overclock with a 65mV undervolt.

Hm. Ok. Fan speed in Wattman is broken. No obvious reason, but when temps or % goes too low, fans switch to max speed instead. No idea why.
