I've posted this before but posting here in the hope others might benefit from it.
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 finally found the solution and it was to do with the default bios settings for my Asus MB and my i9 14900k.
In the document linked here...
https://www.intel.com/content/www/us/en/content-details/743844/13th-generation-intel-core-and-intel-core-14th-generation-processors-datasheet-volume-1-of-2.html
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 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
The comma makes me think you didn't add an extra zero by mistake... What in the actual fuck? I admittedly haven't messed with any CPU clocks since like 2014, but an increase of nearly 16x over stock feels like absolutely bonkers nonsense. Like that just seems so out of spec that your computer should just catch fire. Like the hardware shouldn't even allow it.
In fairness the motherboard not restricting power usage isn't a bad thing: it's not like it's shoving 4000w through the cpu, it's just letting the cpu pull as much as it wants which, with a non-defective piece of silicon, is probably fine.
A modern CPU shouldn't pull enough power that it kills itself, unless there's a major failure in design or manufacturing.
Sure, the CPU gets hotter with more power and sure, the last 5% of performance is a third of the total power usage and probably not worth chasing, but them's the design decisions x86 vendors are making right now and the motherboard (assuming it can deliver enough clean power) shrugging and saying 'whatever' is, outside factors aside, fine.
Also, that 253w TDP limit on a i7 or i9 is a bit low. Yes Intel's spec says that, but intel lies like crazy on power usage, and pretty much always has. These are chips that will happily gain performance up to about 400w of total draw, so capping at half that is a bit of a kneecapping, though it MIGHT keep them from failing as fast, but who knows.
Thanks for the further detail! I suppose I wasn't aware that the CPU was still in control of how much power it could draw.
