Z790 APEX i9-13900k overclock

Suizo
Level 7

Hello, 

I would like to manually overclock my CPU, i have a refence video which he gets it to be stable at 6.0 Ghz (its on an MSI board and i cant find some functions on the Z790 APEX BIOS), with the AI Overclock it brings to 6.1 Ghz but it never really reaches it, it stays at 5.7 Ghz.

Video can be seen HERE

My Benchmark can be seen HERE

Also my component list:

  • Thermal Paste :Thermal Grizzly Kryonaut
  • Contact Frame: Thermal Grizzly Gen 12Th/13Th
  • CPU : Intel i9-13900k
  • PSU :Corsair HX1200
  • M2 (Primary): Samsung 990 Pro M2 1TB
  • M2 (Secondary): Samsung 980 Pro m2 2TB
  • Motherboard: ASUS ROG Maximus Z790 Apex
  • GPU: ASUS ROG STRIX RTX 4090 OC white
  • RAM: Team Group 2x16 GB DDR5 7200 Mhz CL34
  • Tower: Corsair iCUE 7000x RGB
  • Cooling: Corsair iCUE H150i Elite Capellix XT white

If there is any Overclock that bring it to be better. My CPU also runs at 50°C-65°C normaly under load, i would like to get a average of 60°C-80°C at max.

Also if there is a tweak that can be made to the GPU would also appreciate it.

Any response is appreciated if negative or positive.

Thank you

Hello, 6.0 - 6.1 all core frequency is not easily obtainable. Can you confirm your SP Score under AI Tweaker? These predictions will help assess the obtainability. Most of the time, you will be thermally constrained (expect in the region of 300w-350w depending on the voltage needed and workload).


If you're serious, you may wish to consider delidding or using direct die.

Hello, 

I have a MC SP of 71

If the temperatures get higher than expected i might do a direct die custom cooling.

Thank you

What is your P Core SP?

MC SP is memory controller, and that's a little on the low side but not to be concerned if stable @ 7200.

If AI OC is currently enabled, perhaps

Go to Extreme Tweaker > Digi+ and set Loadline Calibration to Level 5

Check AI Tweaker Predictions for voltage needed @ 5.7 @ LLC 5

Apply suggested Additional Turbo Voltage

Set SVID to Trained

Open Extreme Tweaker and go to Thermal Velocity Boost, select TVB Overclocking and select +2 Boost Profile

May net you some performance in certain workloads whilst lowering voltage required.
