Can't POST on startup with DRAM led lit yellow (STRIX Z690-F, i9-12900F, 2x C. Dominator T. 2x32GB)

Hi everyone!

When i tried to enable XMP in BIOS with:

Specs:
ROG Strix Z690-F GAMING WIFI
Intel® Core™ i9-12900F Processor
2xCorsair Dominator Titanium 64GB 2x32GB DDR5 DRAM 6600MHz C32 (Total 128GB)
PSU GIGABYTE P750GM

it can't POST and the mobo DRAM LED light up yellow/orange-ish.

i tried different settings 6600MHz, 6400Mhz (ROG Strix Z690-F GAMING WIFI Maximum), 6000Mhz it won't POST.

the auto is 4000Mhz, and I tried 4800Mhz (Intel® Core™ i9-12900F Processor Maximum) it also had no problem.

My BIOS is also the latest version.

any ideas what the problem is? is it because the CPU? should I change? but I saw that even the latest Intel CPU is only 5600Mhz Max

Any help is appreciated!

1. oh no no no no no. your mixing ram kits. thats a big red flag.

2. your trying to get high speed ram using 4 sticks. you can only get that speed when using 2 sticks. 

3. 128gigs is an extreme amount and extremely hard on the cpu. aint no way you can get that high speed. id probably say 4000-5200mhz only for that much ram.

I'm kinda new for setup pc by myself.

So, even with the same item, brand, series it's a red flag 🤔 aight then 4800Mhz only it is 👀
