Windows 11 24H2 Overclocking Issue

[13oots2]

For years have used specific core overclocking with adaptive voltage on my 10980xe with good stable results. Enter Microsoft's latest and greatest release and all hell broke loose, massive temperature spikes and core 14 constantly loaded to about 50% usage. I reset the BIOS on my ROG Strix X299 E Gaming II and everything ran as it should. As soon as adaptive voltages were used on the cores, temperatures exceeding thermal limits on about 4 cores at fairly low overclocks. Even took the PC apart, cleaned everything and reapplied liquid metal, same problems again. As an act of final desperation, I tried using the built-in A.I over clocking utility on the BIOS, finally I have Windows and software running very smoothly.

Am waiting for a few bits and pieces to arrive today and will then try a manual overclock, I can't understand why Windows would have a conflict with using adaptive voltages.

Awhile back there was a problem with software control of voltages (it was an exploit) and a lot of software was locked down and I think some BIOS even locked it out as well.

I don't know if maybe 24H2 baked something in that is messing with the control, though I guess it could be a scheduling bug, or who knows what.

24H2 made a lot of changes under the hood (still is actually, with every update, even apparently to major components), so I don't think we really have an idea what the heck it has done.

Using A.I overclock ended up with much lower temperatures, most cores are running between 100-300mHz slower than a bespoke method. Seems my latest application of liquid metal wasn't quite as good and have lost 30 points off my cooler performance in BIOS. I balked at the price of Conductonaut and bought some listed as 1 One Enjoy and found it is Silver King made by Thermalright, it even has a QR to check if genuine. Interestingly, the specified thermal conductivity is slightly better than Conductonaut 79W/m-k vs 73, will report back if it is any good, have a couple of projects today now PC is running very smoothly, so will rip the black beast apart again tomorrow.
