The update is mostly for 13 gen and 14 gen CPUs. If you're on 12 gen it won't even apply to you.
Previously BIOS Betas were stable and released as final BIOS versions with no change to BIOS file. But not in this case, the latest Beta BIOS was rushed, Asus even left some debug code in Beta BIOS binary file. And BIOS file didn't include an updated Intel ME.
If you worry about your CPU you can go to current BIOS and enable support for CPU's C1E power state, since this is the biggest difference in new BIOS.
This will start throttle your CPU to 800MHz whenever CPU does not execute any instruction (or is at IDLE), and therefore lower CPUs accumulated voltage.
Quote:
Issue #4: Microcode and BIOS code requesting elevated core voltages which can cause Vmin shift especially during periods of idle and/or light activity.
Mitigation: Intel® is releasing microcode 0x12B, which encompasses 0x125 and 0x129 microcode updates, and addresses elevated voltage requests by the processor during idle and/or light activity periods.
BIOS notes:
1.Updated with Intel microcode 0x12B to address elevated voltage requests during idle or light activity, further mitigating Vmin Shift instability issues.
2.The option to disable C1E in the BIOS has been removed to ensure it remains enabled, reducing processor stress and maintaining stability per Intel's recommendation.
