[SOLVED] Adaptive Voltage Readings

[Phaaze88]

Either there's a key feature I'm overlooking, or adaptive voltage is broken on my board, which would suck - getting this to work would help a little during the summer.
With a total adaptive Vcore of 1.185v on the 7820X for 4.5ghz, the cores are ignoring total Vcore set and still jumping up to 1.23 - 1.31v when cores are active, according to hwinfo.

Windows power plan is on balanced.
Latest bios.
Autonomous C-states control: All C-states are enabled.
Voltage regulator on Balanced mode, not high performance.
Intel Speed Shift enabled, Speed Step disabled. Vice versa doesn't seem to work - unless I need to enable both?
MCE disabled.


LLC currently at Level 5 out of 8. Tried lowering it to 3, then 1... didn't work.
Tried disabling Turbo boost out of curiousity - didn't work.

I haven't ever had an amazing experience using adaptive vcore, with my i5 8600k it's just always unstable, even at 4.8ghz. I'd stick with a static vcore option with LLC set to a medium, high or maybe a flat setting. Personally to achieve a 5.1ghz oc on my cpu, (Which i'm still doing a lot of testing with right now) I've got my voltage set to 1.38 volts with a completely flat LLC setting. I also may try and psuh 5.2ghz if my current oc continues to be stable over the next weeks.

I already found multiple stable cpu and cache OCs for this cpu using manual Vcore, and even tried playing around with Adaptive like 2 years ago, but I couldn't make any sense of it then.

I'm trying to give it another go after finding out that when using Adaptive, the VID readings viewed in both Cpu-Z and hwinfo are merely what the cores are ASKING FOR, and not what the voltage regulator is actually giving them... a bit different when using manual override.

So I'm going to check thermals under both Prime 95 and OCCT using adaptive and manual settings to see if that's true.


Thanks for your input - I wasn't alone with this headache!

Yeah, screw adaptive voltage.
1 minute into OCCT, and half the cores hit my 90C custom throttle limit.
Manual override was fine for the entire 15mins.
