Intel i9 14900 KS on Z690 Extreme Maxiums BIOS UPDATE to Version 4301 no post

Hi, I am running specs mentioned and just wanted to let you know that I can run my i9 OC - no limits with XMP 1 & 2 with BIOS 

Version 4101 works perfectly with my Kingston 128 GB at 5200 MT/s, but when I updated to Bios 4301, it won't post. There was a change that made my setup work worse than before; therefore, I rolled back to BIOS 4101.

Hopefully, someone can explain. Thank you!

I believe this is memory related.

What does the display on your motherboard small OLED panel state when boot is stopped or system reboots

Try forcing N2 at memory timings

Also up VDD and VDDQ voltage by 0.01

I am also running a i9 14900 KS on a Maximus Extreme Z690

Qcode 55

I will test the settings and get back

Yes I believe 55 has to do with memory

So my only message to others is that BIOS 4101 runs stable, and after updating to 4301 XMP 1&2 stops working.

I rolled back to 4101 and it works perfectly fine 😄
