Stable OC 4.9 GHZ Guide on i9-9900K

[iDrakus]

Hello !

i need someone who can help me on this matter.

I use a small case Ncase N1, so I can not take 5 GHz. 4.9 GHz should work for me, but I don’t know how to set it up correctly.

My specs to overclock:
Intel Core i9-9900k + ASUS Rog Z390-I Gaming + Noctua NH-U9S (Air Cooler / Two Fan / TDP 160w)


Thank you in advance!

Hello, this video is the answer you are looking for.

I used debauer's instructions to OC my 8700K on my Maximus X Hero and was solid steady though I had a bad chip.
My 9900K maintains stability on 1.25V @ 4.9G. It can even get past Intel Burn Test on 5G @ 1.24V but fails on Prime95 with DerBauer's torture settings.
Anyway, you can go with 4.9 and 1.25V, run a CB20 see if it's able to pass that and then move on to Intel Burn Test ( 10 , Very High) and then conclude with Prime95, or you could skip all that and stick to the video which is 100% functionable.

Try 1.25V and work your way up or down based on your results.
