Memory instability on ASUS ROG Strix x570-e w/ Ripjaws V 32GB kit

[negzero]

ASUS ROG STRIX X570-E
AMD Ryzen 9 5900X
G.SKILL Ripjaws V Series 32GB (2x16GB) DDR4 3200MHz CL16 Dual Channel Memory Kit 1.35V (F4-3200C16D-32GVK)
EVGA 850W PSU

All bought new this weekend. When I enable DOCP and it pulls the validated config from the kit it works, but seems instability happens. I had 1 instance where it wouldn't post (had to reset bios through recovery) but that was before I upgraded firmware.

Since then it boots / etc. fine from what I can tell, but memtest86 and TM5 with the Anta777 Extreme show errors @ the DOCP 1.35V. I bumped it to 1.375 and am re-running TM5 tests, but wondered if anyone had any other advice? I'm seriously thinking it may be the board, and others in a chat have commented it's a troublesome board. But before I tear the whole PC down and return the MB I wanted to check.

For one, I would update the bios to whatever the latest and greatest AGESA is.

If it runs fine with slightly higher voltage, I would suspect it was the RAM. You could also try bumping the SOC voltage slightly and see if it is stable.
