Finally some good news! Before installing the new ram or messing with the drivers or anything, I figured the easiest next step would be to clock the current ram as slow as possible and try memtest again. The ram is advertised as a 2x16GB kit DDR4 3600mhz with 14-14-14-34 timings. I went into bios and set it to 2333mhz with 14-15-15-35 timings. Ran memtest and didn't get any errors. I have now been running Einstein for 30 minutes! I'll keep tweaking the settings to see what I can get away with but it appears most likely the motherboard didn't like the super tight timings.

You are using a MSI X570 Gaming Edge Wifi motherboard, doesn't it have a setting in the BIOS for RAM to make it D.O.C.P., and that you can set it to 3600Mhz? I only use ASUS motherboards, so I wouldn't know about MSI, but that does make it easier to keep RAM at 3600Mhz.
Also, what type of RAM are you using? For an AMD Ryzen 5800X CPU, I would suggest (if you're not already using it) that you use G.Skill Trident Z Neo (specifically for AMD) which I also use. I've had it for years on both computers, and did the Memtest86+ too, with no faults.
I hope you have more good news and are making progress!

If you were trying run that memory at stock XMP with voltage of 1.35, that is the reason for your memory errors.
The IMC on the Zen processor is the weak link in memory overclocking. To get that kit to run at fast CL14 3600 timings, I had to bump the memory voltage to 1.45V in order to not throw errors or dump the system.
The IMC on the 5800X3D has it doubly hard to run at those clocks.
Good move to return the memory to JEDEC speeds for the tests.
I run my G.Skill F4-3200C14-8GTZ kits at 14-15-14-28-42-294 at 3600Mhz at 1.45V with 120% memory current and LLC3 in the BIOS. FCLK=1800Mhz. Rock solid on 3 5950X hosts on Asus C7H mobos.
Also, just an aside comment that the reason the host holds up under MW tasks is because those tasks don't involve main memory at all. They run entirely on the gpu. Once they are pushed to the gpu by the cpu, they don't have any interaction with main memory at all.

Actually the problematic system I’m focusing on for this thread is the 5800X3D running on a MSI B550-A Pro. The RAM is top shelf G.Skill Ripjaws V Series F4-3600C14D-32GVKA which uses quality binned dual rank Samsung B die IC’s. I’m running Trident Z Neo in the other computer but that’s for a different thread.

Good info about the Zen platform and how MW operates thank you! I was running the kit at stock XMP settings printed on the box. I believe the mother board had voltage at 1.45. I’ve found that if I load the XMP settings then simply change the timings to 14-15-15-35 instead of the stock 14-14-14-34, it’s perfectly stable at 1.45v and 3600Mhz. FCLK is still 1800Mhz. It passed memtest and has been running Einstein for an hour and half so far! I think I can confidently say the issue is fixed, glad I didn’t rush out and buy a new power supply haha. Now I’m going to start a new thread about all the errors on the other computer, thank you everyone.

Okay, all is well in my regards. I'll let you and Keith have at it then.
Well the memory being dual rank causes issues with ANY Zen IMC. Look at the problems on the new Zen 4 plaform which is unable to run 4 sticks at ANY specified XMP or EXPO settings.
It is hard to run dual rank on DDR4 on Zen 3 also.
The business about reducing the Trcdrd value to 15 has been the known fix for Zen 3 for years and well documented at Overclock.net overclock threads. I've been following this thread and picked up all of my memory overclocking pointers from the user experts.

3200MHz is the highest official speed for DDR4, anything above that os overclocked regardless of what your RAM is advertised as. The CPU supports also "just" 3200MHz RAM speed, so unless something is really broken, I'm pretty sure you should be able to run this system stable at 3200MHz RAM clock and with the advertized timmings. That is what I meant with downclocked everything to stock, not just some settings in BIOS. You can try to overclock once you got everything at OFFICIAL stock speed, but keep in mind, that not every system can be overclocked, specially not for 24/7 BOINC.

Sounds like I need to get with the program and finally make an account over there. A bunch of my searches already turn up results from those forums already. Good info.

I forgot about that 3200Mhz factoid. I just followed Linus' advice and went straight for 3600 so I could run the FCLK at 1:1. Since my last post the computer has been flawless. I played 3 hours of continuous VR, half of that in FS2020 without the slightest hiccup. Unheard of up to this point. The last 2 days I've worked 12 hour shifts so no gaming but I've had BOINC running continuous for those 48 hours. No issues at all!
Finally some good news!

That prooves, that there's nothing wrong with your system/PSU except too high (or wrong) overclocking.
