I just finished building my pc and am having weird memory related issues. I have a 7800x3D, Asus Strix B650E-E Gaming Wifi motherboard, and 2x16GB G.Skill Trident Z Neo 6000Mhz CL30 ram(Hynix M die). If I am booting the PC after leaving bios(when enabling Expo), the system starts up without issue and runs without a single crash or error report. I have stress tested the PC for almost a full day and a half using memtest, y cruncher, OCCT, Prime95, Aida64 and none of these tests report a problem or cause a crash/instability. However, when I have the computer shut off and try to power it on the next morning, when it gets to the start up/login screen it is extremely laggy and then the screen goes black, display says it lost signal and the system crashes. It only does this when using Expo, and I have tried, Expo 1, 2 and tweaked. All of them do the same thing. I've even tried running 6000Mhz at all Auto timings. I have tried bios version 1636 with AGESA 1.0.0.7b, version 1654 with version C, and the latest bios to no avail. The Ram is in the QVL and is an AMD Expo kit. Is this an issue with the CPUs memory controller, the motherboard, or is my ram just a faulty kit?

I have already tried all of that. Ram won’t run at any speed above 4800Mhz without the random intermittent cold boot issues, regardless of speed or timings. I have also made sure the bios was always up to date. It isn’t a ram kit issue either as I have tried 3 different brands of ram kits now. One being Hynix A die, one being M die, and another being a Samsung die. All have the exact same issue. As it stands it is either the CPU itself or the motherboard/bios that is an issue. Seeing I am not the only person having issues getting a 7800x3D to work with EXPO, I’d say it’s probably bios related. AM5/DDR5 still being new it will have its issues.

Have you tried lowering vddio mem voltage.
With asus x670 crosshair extreme it raises voltage too high with expo and only post random.
Put 1,25v because on auto its 1,36v
