It says VDD2 1.474 however it is set to 1.450v in BIOS. Also, it says 1.155 for SA but it is set in BIOS to 1.14. I use X7o BIOS. Also, make sure you cool that mem well. Every silicon is a bit different but this would be your starting point. I would leave RAM to default XMP profile, 8000 speed. You can tweak it later. Almost forgot, set your timing for RAM -> Flare. Also, leave the CPU clock speed on AUTO. Do not overclock your CPU until you find a stable overclock for memory. I hope this helps. Leave low latency and high bandwidth options to AUTO. You don't need to have it enabled because you will tweak your timings manually later.

Here is C36 DDR5 8000 which will give you better latency than what you are trying to do with assuming you have a really good cooling for it

If it is unstable keep TX at 1.30. and for SA, start with 1.14 and increase by ten 1.15, 1.16. I bet you will be fine at 1.14. and VDD2 set to 1.45

1.55 should be good enough. Stay with DDR5 8200 C38 for now.

Your SA is too high for the 14th gen. I have the same board and 14900K. Here are the numbers that are going to work for you SA - 1.14v TX - 1.30v VDD2 - 1.45v Btw. If you don't want to waste your time waiting for Karhu to finish, run Y-cruncher and then play BF2042. If you have a slightly unstable platform you will get BSOD or hard restart in BF2042.
