This page lists DDR5-5600 PC5-44800 ECC Unbuffered DIMM (ECC UDIMM) — 288-pin, 1.1V, ECC error correction without a register, for entry servers, workstations and NAS that run unbuffered memory. DDR5-5600 runs at 5600MT/s (5600MHz data rate) for 44.8 GB/s of bandwidth per channel.

What is on this page

Single modules from 16GB to 64GB (16GB, 32GB, 48GB and 64GB), in 1Rx8, 2Rx4 and 2Rx8 rank configurations, plus matched kits up to 512GB total. Use the Module Density, Kit and Rank filters to narrow the list, or Shop by System Model to jump straight to modules matched to a specific machine.

Where DDR5-5600 ECC UDIMM is used

DDR5-5600 ECC UDIMM is commonly paired with AMD EPYC 4005 and Ryzen PRO platforms, and ASUS, Supermicro, ASRock Rack and Gigabyte boards that list 5600MT/s ECC unbuffered memory, plus Dell and Lenovo entry workstations. On this page the system-matched listings cover ASUS, Supermicro, ASRock Rack, Dell and Gigabyte. ECC unbuffered memory is only recognized as ECC on boards and CPUs that support it; on a non-ECC board it runs as standard memory.

Choosing the right ECC UDIMM module

ECC UDIMM is unbuffered — it cannot be mixed with RDIMM or LRDIMM, and platforms that take ECC UDIMM typically cap out at two modules per channel. Check the board's qualified memory list for maximum module density; many DDR5-5600 entry platforms support 32GB per slot but not 64GB. Match speed and rank to installed modules when adding rather than replacing. If you are unsure, send us the system model or the OEM part number and we will confirm fitment before you order.
