Help with Overclocking Intel Core i9-9900k

[N 3 P T U N E]

Hello!

 

I'm running an RTX 3070 and want to overclock my Intel 9900k. I've been using a 550w PSU from be quiet! I used to run a 5 ghz overclock, but after updating BIOS for Windows 11, I lost my overclock settings.

I'm upgrading to the be quiet! Darkpower 12 1000w PSU. My goal is a 5 ghz overclock again, but I don't know what voltage to aim for.

 

My questions are:

1. What voltage should I start testing with?
2. What is the lowest voltage I should aim for?
3. Also how should I go about testing whether my overclock is stable or not?

Lowest voltage that is stable is what you want… 

 

IIRC I used 1.35 to start and adjusted from there. The biggest issue for 9900k is heat. Honestly a 5ghz all core will not be much different then stock.

Thank you!. Any advice on stability testing from your experience?

AIDA64 default test for 8 hours, AIDA64 FPU only for 8 hours, and asus real bench for the longest option which is 8 hours. 

 

If it passes all of that, it’s good.
