- setup for testing only
- VCore set to 1.25vdc
- C1E and EIST both disabled
- CPU-Z v1.40.9b (cpuz.ini - Sensor=OFF to show Core VID)
- reboot and BIOS pix taken

No problems with VCore or any other settings with any BIOS
- maybe the newer revs are the ones affected?
Not sure if you understood correctly but I think he meant the Vcore can't be changed if C1E and EIST is both enabled.

It happens on mine as well, only BIOS up to 1602 I believe didn't have this bug/issue.

Even if I reboot, I can't change Vcore unless I disable C1E & EIST.
