7950x Ram issues

[homiereaper]

I recently upgraded to a ryzen9 7950x and paired it with an ROG Strix x670E-A mobo with four 32GB sticks of trident Z5 6400 CL32 ddr5. The issue I am having is that I can NOT run any higher than the 3000mhz without my rig locking up on powerup for 5 minutes only to boot into bios safe mode and then have to turn the ram clocks down. anyone else having this or a similar issue? Any input or advice would be greatly appreciated.

4 sticks of DDR5 is still poorly supported and implemented, try with two sticks to see if you get the same behavior.

I did try with just the 2 sticks and it ran somewhat fine. Clock speeds were working just unusually long boot times, but no other issues than that. I suspected it was something along the lines of poor implementation for 4 ram sticks, but got a really good deal on the whole kit and hate having empty slots from an aesthetic standpoint. was ust hoping there may be some kind of workaround or something.

This is just an issue with using effectively quad rank memory. Getting any sort of respectable speeds out of 4x32GB is pretty difficult, the most people are able to somewhat easily achieve is DDR5 4000 on them. If you put a ton of effort into tuning the termination resistances and some other settings, I have seen some people be able to get higher speeds to work on those setups, but it's so tedious due to the insane boot times of AM5 and the fact that stress testing time is exponential with RAM size that this will take an insane amount of time to get something like DDR5 5200+ to work with all four sticks installed.
