9900k adaptive voltage

[davegl12345]

Hi,

I was wondering if anyone could explain to me how adaptive voltage works?

I have an asus z390-e and a 9900k cpu.

First, i put the 9900k at 5Ghz, all cores synced, and set an adaptive voltage of 1.30v. However, the reported VID at load is 1.35v, with the vcore hitting that at times. Messing around with the adaptive voltage some more, and it seems i am unable to lower it, at 5G synced, below this value, regardless of what I put in (even tried 0.250v).

Its as if the stock VID is 1.35v, and I have read you are unable to undervolt using adaptive voltage. That can't be right though can it, surely too high?

Weirdly, if I change it to a per-core overlock, and raise a single core to 5.2, now I am getting a VID of 1.31v at all core load (and a vcore roughly that), with the clocks all at 5Ghz.

Thanks for any help

First thing to note, forget about VID, that's not what you should be checking for, instead the value you have to check for is the Vcore.. there are many apps and programs to do that, CPU-Z, HWmonitor, HWinfo64, personally I recommend HWinfo64 for a overall system check...

so check with any of those apps and report back.. also, what are you using to load the system for stability?

and while it is possible to undervolt with adaptive I prefer and recommend always to go with Offset which allow a more granular positive or negative voltage control..

And don't use adaptive voltage. Usually causes me issues than solutions.
