ECC UDIMM - Unbuffered ECC Memory

Full Catalog of Modules across DDR5, DDR4 and DDR3, from 4GB to 64GB per module, at 1333MHz through 5600MHz, in 1Rx8 and 2Rx8 configurations. Coverage is broadest on the platforms that actually use this module type — Supermicro, ASRock Rack, ASUS, QNAP and Dell workstation boards.

The mistakes here are worth naming. ECC UDIMM is not RDIMM — a board expecting registered memory will not post with unbuffered, and the reverse is equally true. ECC UDIMM is not NON-ECC UDIMM either; they share a slot and a form factor, and a board that requires ECC will refuse memory that lacks it. Supermicro encodes this in its own part numbers — EU48 is ECC, UN48 is not — which is exactly the kind of one-character difference that gets ordered wrong.

Use Shop by System Model to filter to your board, or Module Density and Technology Speed to match what's already installed. Send us your board model if you want it confirmed before you order. Lifetime Replacement Warranty on every module. Purchase orders, net terms and volume pricing for business, government and education buyers.
