I have my i9-9900K OCed installed on a Gigabyte z390 Aorus Pro motherboard.
Clock ratio is at 50, turbo ratios at 50 and vCore at 1.300v.
This configuration appears stable; the Thermaltake Floe AIO Triple Rining 360 is connected and has passed stress tests without problems, with temperatures within normal range.
However, some games cause a blue screen after 15–20 minutes of play.
Has anyone had similar issues? Would adjusting the vCore voltage help? I’m considering tweaking it to see if it improves stability.
Also, my PSU is an EVGA SuperNOVA 750 G2.

Could configuring the all-core maximum turbo to just 4900 MHz improve stability? (Consider that only about 80% of 9900K's might reach stable all-core 5 GHz performance, and many will likely require a Vcore adjustment; gradually increase by .01V or .02V and recheck.)
Uncertain about current games' support for AVX or AVX2, but it's possible they use negative clock speed offsets to lower speeds in certain scenarios, which wouldn't be harmful.

Is enabling the all-core max turbo at 4900 MHz stable? Keep in mind, only about 80% of 9900K could reliably hit all-core 5 GHz without stability issues, and most will likely need a Vcore adjustment to reach it. You should gradually increase the voltage by .01V or .02V and test again.

Thank you, increasing the Vcore to 1.310v helped me stay stable. I've been playing Outer Wilds for more than 30 minutes without a blue screen, which might be exactly what I needed. Please let me know if I need to take any more actions.

can you try asus real bench stress test / prime 95 26.6 or prime 95 non avx? what errors would appear? it might need more vccio, vcssa, or higher voltage? could this pass hci mem test?

Thanks for the update, I successfully met all the benchmarks. I resolved the problem by increasing my CPU VCORE by 0.01v.
