This page lists DDR3-1600 PC3-12800 ECC Registered DIMM (RDIMM) — 240-pin, 1.5V (1.35V for DDR3L), ECC, with a register buffering the command and address lines so servers can populate more slots per channel at full speed. 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 1GB to 32GB (1GB, 2GB, 4GB, 8GB, 16GB and 32GB), in 1Rx4, 1Rx8, 2Rx4, 2Rx8, 4Rx4 and 4Rx8 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 DDR3-1600 RDIMM is used
DDR3-1600 RDIMM is commonly paired with Intel Xeon E5-2600 v1/v2 platforms — Dell PowerEdge 12G, HPE ProLiant Gen8 and Cisco UCS M3 chassis. Every part carries the OEM part number it replaces, so a DDR3-1600 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 DDR3-1600 module in a platform rated for a slower speed clocks down to the platform's speed; a slower module in a DDR3-1600 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.
