B550 Semi-random hard-reboots with DOCP enabled - Don't know what to else to try

ragp13
Level 7
TLDR: New PC restarts randomly when DOCP is enabled. Mostly after gaming/when idle. DRAM is on QVL but different set nets the same results. All drivers latest version. Lower frequency/different voltage have no effect.

Built my own pc for the first time again in 15 years.

Specs are:
*Ryzen 5 3600 (stock)
Sapphire RX 5700 XT (driver 20.7.1)
Asus Prime B550M-A (Wifi)
16GB (2x8) DDR4 3200 G.Skill Ripjaws V F4-3200C16D-16GVKB
Corsair TX550M V2 PSU
Crucial MX500 2,5" 1TB

When loading the DOCP profile for this memory, the system is very unstable and can hard-reset within minutes after booting, or after a bit of gaming. Rarely during gaming. Never do I get a Blue-screen (once or twice a green-screen, but might have had my GPU overclocked at that time). It's generally always the pc just rebooting without a warning. Windows Event Viewer always states an Unexpected Shutdown Event ID41 Error.

I swapped the QVL G.Skill memory for (albeit non QVL) but supposedly reliable Crucial BLS2K8G4D32AESBK. Same instability.

- Memory is in DIMM Slots A2 and B2*
- Temperatures are fine
- Running at 3000mhz instead of 3200mhz also results in hard-reboots
- All drivers are the latest version (although I also tried older GPU drivers)
- BIOS is the latest version at 0805
- Benchmark scores and overall performance is normal
- Windows Fast Restart is Disabled
- AMD Power plan Balance/High performance doesn't affect it
- Increase VSOC Voltage with 0.05V didn't help
- Increase DRAM Voltage with 0.05V to 1.40V didn't help
- I've reseated the GPU and DRAM I am reading about some other B550 users who experience similar issues, but also people without issues:*

*I feel like I am running out of options and it's driving me slightly nuts. Just a bad Motherboard? Or poorly supported UEFI at this stage, or am I missing something?

What BIOS version are you on?

Says so in my post 🙂

Sorry missed it. Yeah I just saw another 805 was posted with a new date on the site. I am stable with 608 and not sure I want to upgrade after hearing all these issues. I am on 3600MHz just fine with that BIOS.

The date for 0805 is still the same right? 2020/07/03

Downgrading my Bios through EZ-Flash resulted in a SOC voltage of 1.362, which is unsafe. So I feel like that Bios is doing weird things to my pc and I am not sure if I can trust it...

There is a "new" 805, now with a date of 7/31 on the BIOS download page (support page). Not sure if it's any different.

EDIT: I went ahead updated to 805. No issues running 3600MHz. Corsair RAM model is CMW16GX4M2Z3600C18

as of today Version 1002 2020/08/07, then they removed it?

You should try bios 1002, on my device with 2x G.SKILL F4-3200C16D-32GVK it solved the random reboots.

only thing i had to do is typing in the xmp setting manule. i set the docp plus the rest of the timings as they are recommended by gskill. in my case for the
