It's been a while since I last upgrade my PC, a 6700k was stretched to it's limit on life and will now be relegated to a HTPC / plex server after my 3070ti was getting sub 20fps on Space Marine 2 lol

Got a 12900K because I couldn't quite stretch to the 13 or 14 yet but ddr5 and I have custom loop in my corsair cube case and decent Superflower 750w PSU. I followed the following guide to Overclock it ;


Had to guess a few setting as they don't marry up 100% so probably got something wrong.

Was running perfectly stable with Space marine 2, 6000mhz ram using XMP. Then I tried to run Satisfactory or something else and everything else was throwing a watchdog_timeout_error BSOD when the PC launched a game, so it's clearly unstable. Temps were never over 85c with a 360mm and 240mm thick rad and like 10 case fans running on it.

Can someone give me some guides or tips of what to change on the Asus Z790-p Prime motherboard and corsair 6000hmz ram as to what I should be doing to OC it all. I haven't done it for YEARS outside pressing the auto button but it looks like the auto tuning doesn't do anything with this chip and actually sets the RAM at 5800mhz unless I use XMP tweaked / 3 and then I get the full 6000mhz.

TL:DR

Can I push this ram up higher than 6000mhz and how?

How do I push a 12900k to be stable at high than stock on Asus Z790-p Prime
 
So far as I know, 6200-6600 is usually the limit for 12th gen, so it is possible that the memory controller can't go much higher.
Thanks, I'll tickle the RAM but not expect much more from it then.

The PSU might not be man enough at 750w, I have an 850w Gigabyte PSU I might swap over to as it seems that might be the issue for stability.
