ECC UDIMM DDR3-1600 PC3-12800

This page lists DDR3-1600 PC3-12800 ECC Unbuffered DIMM (ECC UDIMM) — 240-pin, 1.5V (1.35V for DDR3L), ECC error correction without a register, for entry servers, workstations and NAS that run unbuffered memory. DDR3-1600 runs at 1600MT/s (1600MHz data rate) for 12.8 GB/s of bandwidth per channel.

What is on this page

Single modules from 4GB to 8GB, in 1Rx8 and 2Rx8 rank configurations, plus matched kits up to 64GB 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 DDR3-1600 ECC UDIMM is used

DDR3-1600 ECC UDIMM is commonly paired with Intel Xeon E3-1200 v2/v3 entry servers, Dell PowerEdge T-series towers and NAS units of that era. On this page the system-matched listings cover Dell. 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 DDR3-1600 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.
