RMA Maybe

[UnknownProphet]

285K has been unstable when underload. Games crash out rendering is another issue where it will just completely lock up pretty much anything that uses all the cores

XTU used for stress test which is intel's software which i would regard as trusted temps max 101c 

AIO that's being used is in fully working order and has been checked..

Switch back to my alder lake build put the same cooler in along with same GPU set up and zero issues temps are well within 90c rendering no lockups games zero crashing out issues

Hi, UnknownProphet.

Thank you for posting in our Community and for sharing these details. Based on your findings, it seems like the instability is specific to the Intel® Core™ Ultra 9 Processor 285K, especially under heavy loads like gaming and rendering. Given that your AIO cooler is functioning properly and your Alder Lake build runs stable with the same setup, we may need to explore potential causes such as thermal throttling, power delivery, or BIOS settings.

You mentioned switching back to your Alder Lake build using the same cooler and GPU setup without any issues, temperatures staying within 90°C, no lockups, and no crashes during rendering or gaming. Could you share the model of the Alder Lake CPU or the components you used for the swap test? Do the crashes occur in all games and rendering applications, or only specific ones?

Have a nice day!
