After overclocking my 9700k to 5ghz at 1.370v, I did a stress test with intel burn test at the "very high" for 10 rounds, it passed it with no problem, but then it just keeps crashing randomly after playing games for multiple hours? What may be the issue here? I read that 5ghz should be fairly easy to achieve, so I assume its not my chip that's the problem. Ive also tried raising the voltage up to 1.390v. my motherboard is MSI z390 A-pro and ram is gskill ripjaws 3200mhz. I'm using the default XMP on the mobo for my ram.
