    I agree. I have ran my 5900X on both the CH7 and the CH8, very similar experience, biggest difference is CH8 has PCIE 4.0 which isn't a must have for most people. A good old Samsung 970 Evo Plus PCIE...

    It started with the V2 bioses for me, I had UR22C working flawless in USB 3.1 gen 1 mode and from those bioses it went disconnecting on both CH7 and B550-F. Switched to USB 2.0 and it works, but yes...

    DOCP seldom works so far, setting timings/voltages manual works very well, so yes AMD is not for total beginners as of yet(unless someone helps them setting things up)

    It's certainly not RAM by itself, but it can be FCLK behind these errors and it is coupled to the memory bus. As earlier has said, trimming SOC, PLL, SB, VDDP and VDDG may solve the issues.

    I...

    No, it has only two RAM slots and more high quality traces, it's for extreme memory OC.

    Problem is you need to do a lot of settings by yourself, D.O.C.P is usable only for a few.

    I have four Ryzen systems running happily with 3800, 3800, 3200 and 3000 MHz memory. All far above their...

    On further comment, this was a great question asked, it inspired me to find my "bad" core/cores. Turns out Core 1 on my 5900X is a lot worse than all the other cores, it easily spits out WHEA errors...

    Glad you could fix it, but yes, basically if two cores needs more volt than default to even boot - your CPU is faulty. Bad QC from AMD. It may overclock bad, that would be ok, but not running default...

    The chip only supports 3200MHz memory, anything above is OC and can't be guaranteed. Also DOCP support is sketchy. The best way to run fast memory is to do the settings for timings/subtimings...

    I'm mainly talking about Ryzen 5000 and their happy boost to 5150MHz, with CO, which possibly is problematic. You run Ryzen 3000 so you are not affected much.
