ROG STRIX B660-G GAMING WIFI [BIOS 2611] offset voltage

[physbyte]

offset voltage are broken? same settings in bios.

I also noticed that the larger the offset, the larger the jump.

Actual VRM Core Voltage: Offset mode

Offset Mode sign: -

CPU Core Offset: -0.130

BIOS 2603

BIOS 2611

2611 offset -0.200

 In windows without high loads i can get core VIDs spikes to 1.4+V (offset 0.130)

Hey Physbyte,

Access the "Tweaker's Paradise" section in your BIOS settings. Look for the option to switch to a previous microcode version. Choose "Microcode 104" from the available options.

• Actual VRM Core Voltage should be set to "Auto."

• For Global Core SVID Voltage:

  • Set Offset.
  • Set negative sign.
  • Set your desired voltage offset.
  • Configure the Cache SVID Voltage the same as above.
    
    See if this works.

It looks much better! is it safe?

Cool. 104 Microcode from Intel best for undervolting here.

Can't see SuperIO reading for vcore, only the VID. No reason why it wouldn't be "safe", though

For some b660 boards

When changing Global Core Svid voltage to manual, there is no offset, just an override.

What that override means and how can you undervolt from that?

Thanks

Any ideas?
