Hi everyone
Last week i built my new pc with
I9900k
Asus rog maximus hero xi wifi
Rtx rog strix 2080
64 gb ram 3200 vengeance pro rgb
m2 970 evo Samsung
850w hxi corsair
Corsair h150i

I try 5ghz and ram 3600 mhz cpu voltage1.29v or 1.35
Avx-4 , llc6 ,all power management disable
With this oc the system is extremely instable and crash during stress test

After i try 4.8 ghz with 1.25 v ,ram at 3600 , avx- 4
The system work done with stress test
I try prime 95 at small test and temperature not goes over 82°c, in normal test stay around 75°c
I run prime 95 and kombustor to test all systems and goes very good

But every time i launch game , windows crash with blu screen or game randomly crush

I try video games with default bios setting and work very fine but i try li#ght oc fo vga with asus oc games randomy crash

Why i can run oc in stress test but when i launch games windows crush?
I had to try lower oc to 4.4 ghz ?
Why vga oc isn't incompatible with video gm#

That is the nature of overclocking. Stress tests are a guide...not an absolute test of stability.

When you are OCing, be methodical. Start with defaults and set you ram to rated speeds...stress test but also test your daily uses gaming etc.
Then OC the CPU and do the same
Then OC the GPU...all the time testing and tweaking

Through all this...don't let expectations and other people's results and listen to your particular system.

You say?
Ok today i read all guide and try to start from standard value
I had to find right way to perfect daily oc
I can

Sure you can...

One thing...is your RAM a single kit?

Yes one kit of vengeange pro rgb ddr4 3200 mhz 4x16gb

What is the overclock order?
First cpu
Second gpu
And last ram

BSOD means your almost stable, it won't boot then your OC simply fails.
Since your so low on the clocks, i would revert the RAM OC and GPU OC and head back into the BIOS and work on the CPU.

I am using the same board but a 8086k so i can overclock higher then a 9900k i made a guide based of my experience with the board i might give you some insights: https://www.hisevilness.com/articles/technology/intel-i7-ocing-the-8086k-on-z390.html
