Wait, where are the UDIMM 48GB DDR5 Ecc dims?

My Ryzen ASUS model history is:

  1. AM4: Pro WS X570-ACE

  2. AM4: ProArt X570-CREATOR WIFI

  3. AM4: ProArt B550-CREATOR (that model has build quality issues, noticed loose USB-C ports on multiple units purchased a year apart, no issues on the very same USB-C ports of numerous ProArt X570 units)

  4. AM5: ProArt X670E-CREATOR WIFI

Was late to the AM5 party and honestly think the ProArt X670E is the only “great” motherboard model out there so far, every other one is like “meh” from a PCIe or peripherals connectivity standpoint.

I still don’t understand why there isn’t a single AM5 motherboard that uses its 8 M.2 CPU PCIe lanes to instead provide an additional x8 CPU PCIe slot, in theory making a x8 (CPU), x8 (CPU), x8 (CPU), x8 (X670E) PCIe slot configuration possible.

How I check for ECC:

  • Check Windows terminal to see if it detects Ryzen’s Multi-bit ECC

  • Undervolt and overclock the memory to the edge of a system not POSTing to force actually occuring memory errors under heavy load

  • Boot up PassMark Memtest Pro, an example:
