Page 98, Table 17, Row 3: Reveals the stock turbo power limits for the 13900K and 14900K CPUs are 253W, not the 4,000+ my MB’s Bios settings default to.
Page 184, Table 77, Row 6: Lists the maximum current limit at 307A, far below the MB’s default of 500+A.
I was having issues with crashes in multiple games but rdr2 was the worst. I had a rig built with an i9 14900k and Asus hero z790.
I think I finally found the solution and it was to do with the default bios settings for my Asus MB and my i9 14900k.

I found this information in a Reddit post (https://www.reddit.com/r/overclocking/comments/1axepvu/optimizing_stability_for_intel_13900k_and_14900k/) and followed the settings as follows:
ASUS Z790 Motherboards:
Save your current settings into a profile so you can return to them later if you want.
Reset your BIOS to default settings. Ai Tweaker tab:
Disable MultiCore Enhancement.
Enable XMP(if your RAM supports it).
Set SVID behavior to Typical Scenario.
Set short duration turbo power = 253
Set long duration turbo power = 253
Set max core/cache current = 307Amps
Doing this immediately stabilised the CPU temps as well as bring down the average temp by ~10 to 15c. It’s been a few months now with zero crashes.
Hope this helps someone
