[SOLVED] Unstable while gaming but not during stress test

Feb 13, 2019
As I said in my previous post, I have a 9600k overclocked to 5.07 GHz. I have a Gigabyte Aorus z370 ultra 2.0 motherboarf. I have my core clock speed to 51 and voltage at 1.355v. When I run a stress test, it is stable at about 78c. But while gaming, bluescreen shows up (whea_uncorrectable_error) also when I put my clock spped to 52, it won't boot. Same error code shows up. My cooler is running at max
What PSU do you have? When you're stress testing i'm guessing your only doing the CPU to make sure its running fine, but under gaming the whole system is stressing the PSU and i would fair to guess its not holding the cheese on voltage to keep your CPU stable.
