Is my CPU adhering to the 1.55V limit or not?

[Gessler]

I had flashed the 1503 BIOS (the latest one, with the 0x129 microcode) for my Z790-E Gaming WiFi II earlier but the peak VIDs on my 14700K were still going as high as 1.565V despite being on Intel Default Settings profile, well above the 1.55V VID limit supposedly imposed by the new microcode.

I flashed the BIOS again (with a fresh download of 1503) and now I'm getting multiple cores with a peak VID of 1.555V (pic attached) under gaming loads.

I'm wondering if this means that the limit is finally being adhered to? Does it still count as 1.55V as long as it doesn't touch 1.556V?

Hello,

The VID and the realtime voltage are not the same. Assuming EVTB is enabled the voltage cap will be 1.55v. Vcore can be seen under the SuperIO section in HWINFO.

I've never seen my Vcore reading go above 1.518V so there's that.

ETVB is set to Auto by default (haven't changed anything after updating the BIOS and hitting F5 to set UEFI defaults).

So you're saying anything above 1.55V will never be given to the CPU, even if it asks for it? As long as I'm on Intel Default Settings profile?

Only Intel know how the voltage cap is being enforced, or how well it's enforced - but it was tested prior to being rolled out and the team confirmed that the voltage does appear to be being capped at 1.55v.

I see.

So that brings me over to my original question. Can I consider the voltage as being at 1.55V as long as it's above 1.546V but below 1.556V?

Or is it 1.55V from above 1.549 all the way to at or below 1.559?

Just wondering how the decimals are calculated.
