This page lists DDR4-3200 PC4-25600 ECC Registered DIMM (RDIMM) — 288-pin, 1.2V, ECC, with a register buffering the command and address lines so servers can populate more slots per channel at full speed. DDR4-3200 runs at 3200MT/s (3200MHz data rate) for 25.6 GB/s of bandwidth per channel.

What is on this page

Single modules from 8GB to 256GB (8GB, 16GB, 32GB, 64GB, 128GB and 256GB), in 1Rx4, 1Rx8, 2Rx4, 2Rx8, 4Rx4 and 8Rx4 rank configurations, plus matched kits up to 4TB 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 DDR4-3200 RDIMM is used

DDR4-3200 RDIMM is commonly paired with third-generation Intel Xeon Scalable (Ice Lake-SP) and AMD EPYC 7002/7003 (Rome/Milan) platforms — Dell PowerEdge 15G, HPE ProLiant Gen10 Plus, Lenovo ThinkSystem V2 and Supermicro X12/H12. On this page the system-matched listings cover Dell, Lenovo, Hypertec, HPE and ASRock Rack. Every part carries the OEM part number it replaces, so a DDR4-3200 order written against a Dell, HPE, Lenovo, Cisco or Supermicro part number can be matched line for line.

Choosing the right RDIMM module

RDIMM and LRDIMM cannot be mixed in the same system. Within RDIMM, match rank organization (1Rx4, 2Rx4, 2Rx8) to what the platform already runs where possible — mixed ranks are usually supported but can lower the effective speed. A DDR4-3200 module in a platform rated for a slower speed clocks down to the platform's speed; a slower module in a DDR4-3200 platform pulls every channel down to the slower speed. If you are unsure, send us the system model or the OEM part number and we will confirm fitment before you order.
