i9-9900KS overclock error

[EzzatLiao]

Hi after getting my i9-9900ks I tested few times everything run smoothly hitting 5ghz @ 1.24V but as I used normally I ran into this 2 bluescreens any idea? The WHEA uncorrectable error usually happened when I open alot of stuff/app and switching between the app, I assume RAM issue but it’s a 50-50. As for clock watchdog error it’s a bit random. Please refer the images for error message.

 

PC Specs:

i9-9900KS

Z390 Aorus Master

RTX 2060 Super

HyperX Predator 3200mhz 8GBx2

NZXT x72 mod with Noctua A12x25

EVGA G+ 1000W

Hello,

 

Did you try with more core voltage ? 1.24V is particularly low.

Yup I did pump up to 1.26V but still persist @Plouffe

Usually at 5GHz, it's more around 1.3-1.35V so try more (max is 1.52V and if possible not above 1.4-1.45V).

But this is i9-9900ks tho, watch optimum tech on youtube hitting @ 1.18V @Plouffe

That's the loterry and he got lucky. Most people will run it at 1.3V

Some chips will perform better than others.

KS will run at 5GHz stock at default voltages, you can try to undervolt but each chip is going to have a different lowest voltage it can still run 5GHz at.

But mine all test run aida64 4K video rendering is running without error with 1.24V that’s the weirdest part @Kilrah @Plouffe

Did you try Prime95 for 24h ? It's the best way to see a good OC.

Silicone lottery and voltage stability, have you checked HWiNFO to see how much your vcore fluctuates?

My i9 9900ks in z390 bsods all time also Shows ultra los vcore of 0.88 At idle the  crashs
