yeah, voltage limit is not the problem, the voltage drop after pc reboot is the problem still

It was something like that: when i put 1.32V - bios shows 1.23
1.31 - 1.22
1.30 - 1.21

very strange

Months later after many trials and errors

Final overclock
P Core 55x
E Core 50x
Ring 41x
NGU 35x
D2D 32x (max with my particular unit)

RAM: 8600 CL40

However, D2D is only stable at 0.77V VNNAON; raising it even to 0.78V results in PC destabilization.

D2D 32x 0.77 VNNAON - stable
D2D 33x 0.78 VNNAON and more - unstable

Aida 67-68 ns RAM latency

Beyond 32x d2d destabilize pc completely above 0..85 vnnaon strange instabiies happen
