13900kf 5.9 all cores (trying for 6ghz)

By


I’m trying to hit an all core 6ghz oc on my machine. I’m currently at 5.9ghz all core with E-cores disabled. What do you guys think of these setting choices? How can I improve on this OC, and achieve 6ghz all core? Here’s my specs and settings (full bios options in attached pictures):

13900kf + icue 150i elite capellix 360mm
Aorus master z790
Corsair dominator 7200 CL34
Rtx 4090
E-cores disabled

Fixed vcore: 1.45v (Adaptive Vcore brings my Vcore to 1.5v+, which I don’t want)
CPU Vcore LLC: UltraExtreme (Low causes green screen of death)

UltraExtreme Vcore LLC makes the CPU run a lot hotter, like 15°C more, which is unfortunate, but it makes thr OC stable.

    FYI, you can use Adaptive voltage but will need to limit it using the “max turbo voltage” option. Regardless, fixed Vcore is fine for what you’re using. However, if you need 1.45v for 5.9 Ghz, you’re going to hit a wall at 6 Ghz.

    What is the fused VID for 6 Ghz?

    I can’t get 6ghz all core stable using UltraExtreme Vcore LLC and fixed vcore 1.45v. Im considering trying 1.5v but have googled how 1.45v+ for 13900k isn’t a good idea.

    5.9 all core with High LLC still crashes. I have a feeling Turbo would be stable, but I’m concerned about CPU degradation. Would Turbo Vcore LLC hurt the CPU that much?
