Z690 hero ddr5 help needed pleasee

[Purebliss]

Hello, I’m urgently in need of help.

I have an asus z690 hero motherboard, Corsair dominator platinum 64gb 4x16 ddr5 5600. And 12th gen i7.

I was using the pc with ddr5 at full speed after  putting voltage to 1.3 from 1.25 and setting by per  pmic. This was working fine for some months, then I changed an aio cooler and some issues arrived, I found out it was Corsair commander, but getting to troubleshoot the issue I ended up resetting my bios and even formatted the pc. Now for some reason I can’t seem to get the pc stable again and I keep getting bsod and errors when trying to game where it just crashes. I’m not sure if when I reset cmos it reset something else that had been changed before, I’ve been trying for 8 days to resolve this issue and get it stable again. I’m not amazing with computers but hoped that someone on here might have some info or help that can get me running stable again without all these bsod and errors/crashes gaming.

Thankyou in advance for any help it’s really appreciated, I wish there was a good specialist in Sheffield I could take the pc too as it’s driving me crazy now. 🙂 
p.s I’m on the latest bios as of this moment posting this, I believe 2305 bios is the correct version but I have checked and there’s no newer bios revision.

Hello,

Sounds like memory instability after the system has retrained after clearing CMOS, the applied overclock isn't stable.  Could you please verify:

1) Memory kit part number

2) If the behaviour desists after clearing the CMOS (no XMP active or CPU overclocking)

Thankyou very much for your reply,

the ram does seem more stable without any xmp, when I 1st got the ram I couldn’t even load a game without instant crash, then I watched a video saying how to run 4 sticks ddr5 at desired  speed here is the short video so u can see exactly what I did https://youtu.be/1KZFeE-o3jo

that seemed to fix everything until I reset cmos, I’ve tried doing same instructions from that video.

I’ve no overclockers on cpu, I just wanted my 4 sticks of ddr5 to run at more than the 4000 speed it sets it too in bios. My cpu is i7 12700k and all temps seem really good.

the part number of the ram on the box is CMT32GX5M2B5600C36 I purchased 2 identical boxes. It’s so frustrating that it was running great till I stupidly reset the cmos to try resolve another issue that was a Corsair commander wire been loose.

thanks for your time and help.

Hello,

Combining or mixing memory kits is not recommended or supported by the motherboard or memory vendors.

You'd need to remove one of the kits in order for the XMP profile to be valid, or tune the system manually.
