8086K | CPU-Z misleading Vcore HELP!
Hey, first off, I run an 8086K on an MSI Z370 GAMING M5
So after almost one whole day of me trying to figure out WHY CPU-Z is showing Core VID a lot higher than my UEFI Vcore manual setting, after finding out about LLC and researching the hell out of it for hours (actually at least I learned a bit of it too so cheers for this), after trying to figure out what am I missing although I did not modify many other settings in the UEFI, and trying to make out my OC steps backwards (because I saw the Core VID a lot higher than the UEFI a lot later in my OC) I somehow remembered where have I seen the actual "correct" readings, and that was in CPU-Z 1.90. At some point I updated to the latest which is 1.92. So I redownloaded the 1.90, and in it I now see again the "correct" Vcore which is the same as in my UEFI, 1.280 for 5.0 GHz all cores OC. After I saw this I quicky checked with HWMonitor, and there is reads 1.310-1.365v as in CPU-Z 1.92, so now i'm thinking that this is the correct value now, and the CPU-Z 1.90 and 1.91 readings were incorrect. But what I still don't understand is why is the Vcore a lot higher than my UEFI manual setting at 1.280v? After googleing, I saw that 5.0 GHz on an 8086K should have Vcore between 1.225-1.350v, so I thought I was safe at 1.280v based on CPU-Z 1.90 as I kept monitoring it (but now I think that the Vcore was a lot higher based on CPU-Z 1.92 and HWMonitor actual readings). As I learned from researching LLC is that for example I should have seen readings of 1.280v in CPU-Z only in idle and lower readings in load, but my problem is that the Vcore readings are higher than that... I tested with LLC Mode 8 at 1.350v and the readings were the same! 1.310-1.365v. So there was a bug in Vcore readings on older CPU-Z versions? I checked the changelogs and there was nothing specified about it. WHAT AM I MISSING HERE PLEASE?! In the screenshot you can see both CPU-Z 1.91 and 1.92 COre VID readings.
EDIT: Now I see that CPU-Z 1.91 didn't have bad readings at all... 1.90, 1.91 are showing the Core Voltage while 1.92 is showing the Core VID, they changed the sensor reading in that sensor space.
Other UEFI settings:
All Turbo settings disabled
All eco settings disabled (EIST etc)
