32M?

I loaded the quick 8400 profile and changed the timing to 36-46-46-46-64, Trefi Max. Set memory voltage to 1.5/1.5. Left default 1.4/1.4 for TX and VDD2 and set SA to 1.25! Works awesome.

x7u is an excellent BIOS. DDR5 8400 A-Die C36 + 14900KS

Says it is not a proper BIOS

What's new in this version?

As I said xo BIOS requires 1.14v for SA and Official Gigabyte BIOS F11b -> 1.3v for the same memory setting. As I said different microcode yields different results for whatever reason.

Different Microcode gives me different Mem OC capability going from 8000 to 8400. In some, it requires SA 1.1-1.14v, and in some 1.3+ for my 14900k. Your settings for 14900k are completely off for my 14900k.

It is not about performance gain. Asus Apex got recent xoc bios based on a new microcode that enabled some people to run higher memory frequency.

Hi again, Are there any plans for a new BIOS based on the latest microcode updates? Thanks.

Is there any plan for a new bios based on the latest microcode?

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.
