Help me to find a ATX Main board with ECC that is not for gaming + tower case

[David Hess]

All DDR5 implements limited ECC internally as part of the bus interface and *not* the sense amplifiers.  Data is corrected in the bus interface, but is *not* automatically written back to the DRAM array, so no scrubbing takes place.

Will then the outside world get notified it such a correction on the bus interface happened?

I assume some sort of status word is updated internally and made available to the memory controller on demand, but I could not find it in the specifications.  Scrubbing would require the memory controller to write that word back.

The reason that the ECC is done in the bus interface and not when loading a DRAM row is that the later would require too much power.

Anyway now I am pretty convinced it is a old BIOS topic, I ordered a AMD Ryzen 3 3200G on Amazon that I will return 5 minutes later after the BIOS is upgraded.

It works, but I lost a year of life plus a kidney.

Removed everything, installed the 3200G. POST finally ok, BIOS 4201 on the effing MB.
Upgraded to 4402.

Swapped back the ebay used 5900X, installed a good known graphics card.
NOTHING LED VGA STUCK ON.

Just because it was on my desk, I swapped the 5900X with the brand new 5950X.
Guess what, now that bastard boots.

Why on earth the boot error VGA LED is on and if I swap the CPU it boots fine? Thanks ASUS to point me in the wrong direction.

I am so wasted I will now keep the 5950X and sell for parts the 5900X at loss.

Currently hammering the 64GB ECC with memtest86, next step Win10 check if everything is recognized okay and the prime95 as final test.

Wish me luck.... I feel like I am painting without eyes.

After
- 12 pass tests with memtest86
- 24h of prime95
- about 30min of 3d furmark
- some other GPU memory checks

I declare my new machine stable and ready to host arch linux.
