i9 9900KS - Unstable OC - What am I doing wrong?

Hi,

I got a 9900KF that I put on my Aorus Master Board today but I can't manage to get a stable 5Ghz OC, I just did some cinebenches to stress it out and i planned to do some occt when it passes but...

I managed to get all cores 48 with 1.2 but goint to g5hz seems impossible, i went to 1.3 but got BSOD during Cinebench R20

Here are the setting i am using right now, what can i do to achieve a stable 5Ghz ? Thanks !

CPU Base clock 100
CPU upgrade : auto
Enhanced multi core performance disabled

Intel Speed Shift Technology: Disabled
Uncore ratio : auto (43)

Those BSODs you are getting are most likely thermal related. What does your cooling look like. The 9900 runs hot.

Already am helping him on reddit. He has a 9900KS. He should not be getting BSOD's at voltages HIGHER than my average 9900K is running at, in a potato program like Cinebench R20.

*EDIT*
His screenshot shows 9900KF. He doesn't have a 9900KS ...

I often speak with @Elric2a , and I have a 9900KS so he just swapped :-)

He have a 9900KF (P0 if I'm not wrong) and AIO (corsair h150i)

It's hard for me to give advice because I have asus apex XI (with die sense), and I don't know gigabyte bios as well as you @Falkentyne

h150i should handle 9900KF @1.3V easily.

set 50x, avx-2 @1.3V, use AIDA64 CPU test, see what will happen.

I just did a quick test by pushing vcore a bit and i set up core clock ratio at 50, no avx offset,
The turbos are disabled but by putting core clock ratio at 50 it was only going at 48, why?

but anyways i did a R20 cinebench at 1.32; and the temps are I think way too high no
