ECC UDIMM DDR5-4800 PC5-38400

This page lists DDR5-4800 PC5-38400 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. DDR5-4800 runs at 4800MT/s (4800MHz data rate) for 38.4 GB/s of bandwidth per channel.

What is on this page

Single modules from 16GB to 48GB (16GB, 32GB and 48GB), in 1Rx8 and 2Rx8 rank configurations, plus matched kits up to 384GB 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 DDR5-4800 ECC UDIMM is used

DDR5-4800 ECC UDIMM is commonly paired with Intel Xeon E-2400, Xeon 6300, AMD EPYC 4004 and Ryzen PRO platforms — Supermicro X13, ASUS and ASRock Rack boards, Lenovo ThinkSystem entry servers, HPE ProLiant MicroServer and ML entry servers, and ASUSTOR NAS. On this page the system-matched listings cover Supermicro, ASUS, Lenovo, ASRock Rack and HPE. 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 DDR5-4800 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.
