Question 13600k maxes at 100c during gaming and testing, whats wrong ?

[vortex01]

I have been having my games crash in windows with dx issues and random crashes, gpu driver up to date and I am using 7200mhz mem on Win 10 Pro with 13600k and Z790 board. Im thinking the ram is the issue cause P95 didnt crash when I used 6200mhz cl36 GEAR 2 settings, but did crash when on XMP 7200mhz cl34. For all tests I used XMP and manually chose the speeds in the MSI bios. I also read I should be in GEAR 1 settings for ram but idk what that does or if I should even touch it. I have been stuck on 100c for my P core and close to 100c for my E core and Idk whats going on. I benchmarked some settings and I am hoping you guys can give me an answer for my trouble. My thermal paste and the anti bend bracket are secured and fitted on correctly so I am lost as to what it might be.

Running memory at 7200MT/s (DDR 3600 MHz clock rate) is pushing the envelope, even if it's in your motherboards Qualified Vendor List.

It's hardly surprising that tightening the CL setting from 36 at 6200MT/s to 34 at 7200MT/s makes things worse. You should try loosening the timing to CL40 or CL42 at 7200MT/s. Even then it might not be stable.

A few extra percent in memory bandwidth will not make any significant difference in most apps and a stable machine is far more important than a system that keeps crashing.

As for the high temperatures, they're quite normal when the CPU is boosting hard. Intel systems boost to 100C whenever possible for maximum processing power during some games and rendering apps. Don't panic.
