Question PC is not booting after xmp profile enabled

[pumpkins]

Hi guys,
As the title says, I can't boot my PC after enabling XMP profile after which I have to restart CMOS in order to boot it again. I Don't want to work on 2133Mhz RAM when I paid for 3600Mhz, and any boost in productivity is needed for my job!
These are the specs:

GPU: Gigabyte RTX3060
CPU: intel i9-12900
MOBO: GIGABYTE B660 AORUS MASTER DDR4/1700
RAM: 4x CORSAIR Vengeance C18 CMW8GX4M1Z3600C18 8GB(1x8GB)/DIMM/DDR4/3600MHz
PSU: GIGABYTE P850GM 850W/ATX/80PlusGold
SSD: SSD CORSAIR Force MP510 960GB/M.2/NVMe

If any additional info is needed, feel free to ask!

Turn off XMP and boot into Windows. Find and install CPU-Z. Go to the SPD tab and take a pic, or write down all the JEDEC/XMP timings. Go to BIOS and set the slowest one, see if you will boot. Continue this process with the faster settings until it won't.
In some cases, you can relax the timings a bit to get a successful boot, but of course with that somewhat defeats the "speed" you are shooting for. Also of consideration is to make sure what voltage is being applied (or not) with the faster timings.

return the ram and get 4x8GB kit.

Proper bios?

Will this be beneficial for people just looking for extra performance, even without issues?

ver. f5

There are a few newer versions you might want to try.

It is a method by which to find the fastest timings your RAM/mobo combo can boot when not working automatically with XMP (etc.)
