Hi All,
First - thanks for taking the time to help me with this. Lately I've been feeling entirely cheated by the hardware manufacturers. Building a PC used to be a fun endeavor for me, but, I guess, as I'm aging with kids, etc. these not-so-straightforward issues are really starting to grind on me. I did search the forum and found some close-but-no-cigar solutions. I have spent weeks of ordering and swapping parts to get to this point.
Setup
PSU - EVGA 750w
Mobo - Asus ROG z-690-e Gaming WIFI (upgraded to latest BIOS ver 3302)
CPU - Intel i9-12900k
RAM - 32GB (16x2) Corsair Dominator Titanium 6400 (32-40-40-84) 1.4V ver 5.43.01
GPU - RTX 3080Ti
HDD - M.2 Samsung 990 PRO
Background
It took me forever to get this machine to post. With both sticks of RAM in (in the recommended A2 and B2 slots) I would get a 5-round boot loop and then PostCode 55 (no memory found).
Finally, after reading a bit online, I tried it with 1 stick of RAM in A2. Voila. I could get the damn thing to boot to BIOS, but it automatically downclocked the RAM to something like 3400Mhz.
After playing with the XMP profiles and upgrading the BIOS, I was able to get the board to boot with 1 RAM stick in A2, at the RAMs rated 6400Mhz. I think I used the XMP II profile with a slight upwards voltage adjustment that I saw on a YouTube video. However, I've not yet been able to get it to boot with both sticks installed in A2 and B2. Swapping the sticks does nothing, and it will boot with 1 stick in the A2 slot.
On a whim, and with a little bit of oldschool knowledge, I popped both sticks in A1 and A2 and the sucker booted. And it was stable... for a day.
Then all hell broke loose. I corrupted my video drivers and then Windows completely took a crap. Now I'm back to a fresh install of Windows and 1 RAM stick.
I'm feeling pretty defeated in what used to be a fun hobby of mine. I've never been into overclocking - I just want to play video games and have a stable machine for work.
I don't believe I have any hardware failures at this point, I just need the settings that will work. Any ideas?
thanks,
