Updating BIOS increases CPU voltage

[MoonMoonTheDoge]

Hello everyone!

Just registered at this forum.

Well, I guess the title is self explanatory, I updated my BIOS to the latest firmware and now, when overclocking my cpu (automatically by game boost to 4.4Ghz) it increased roughly the voltage by 0,1v.

This may not sound too much but to me it is. I had the voltages at 1.246v and now I have them at 1.360v.

please help!

 

Uploaded the results, before and after update.

 

Specs:

Perhaps in the new BIOS update msi felt that the 1.260v was not enough for the auto 4.4ghz oc so they decided to step it up in an update to improve stability?

Reduce the voltage manually, or reduce Load Line Calibration.

Greetings, I agree with @BaileyFY. I would recommend calling MSI support to confirm.

In any case the max safe voltages for 24/7 Skylake are, so OP should be fine.

 

Safe Voltages
Vcore: 1.45v/1.4v
VCCIO: 1.25v/1.2v
System Agent (SA): 1.3v/1.25v
Vdimm: 1.4v/1.35v

But in your opinion what's the minimum voltage to 4.4GHz?

That is very CPU dependent, as they are not all created equally. You would need to start low with your overclock and stress test for stability.
