Question DDR4 - two sticks crashes, one stick is stable

This is really turning into a puzzle. This is a new build using an ASUS X570-Plus MB with a Ryzen 9 CPU and Nvidia RTX 3080. The MB came bundled with a pair of "cheap" DDR4 (2x16GB) branded "Neo Forza".

Initially the system (running Windows 11 Pro) seemed to be working well but once under any kind of load it would reboot, often without even a BSOD [well, "green" now]. Checking the Event log after restart I'd find "A fatal hardware error has occurred" with the component identified as "Memory".

Trying to diagnose this, here's are the things I've tried so far:
  • Pulled the DIMMs and swapped position to reseat them
  • Ran MS memory diagnostic tool: first run found no errors, second run rebooted before finishing
  • Pulled one of the DIMMs and ran on a single stick: with one stick, I could push the system for hours without a reboot
  • Bought a pair of 2x16GB DDR4 Crucial sticks to try: same results as with the "cheap" sticks
  • Checked that the BIOS didn't have any aggressive overclocking settings engaged
At this point I'm at a bit of a loss; it seems like it's not the RAM since I'm getting the same behaviors with two different sets and it only seems to occur when I have a pair installed - like whatever is in charge of the "dual" aspect of DDR is failing or ??

Any insights from the hive mind are greatly appreciated.
