when you done all this - i will go now for an nice nap
Now go for DIGI+ Power Control (in Bios)
Put Load Line Calibration on "Medium"
CPU Current capability put on 130%
VCCSA Load Line calibration put on "Regular"
VCCSA Current capability put on 120%
Anything else leave like you find it
If you gott any problem with this (BSOD or freeze ) Put back CPU LLC to high
Now you have an good point to start with experiments and "what if's"
Go to BIOS "TOOL -> ASUS O.C. Profile - Name it like safe 42 and save it - if you stack anywhere in this jungle OC you can always recall those settings and start from begging .
