This page lists DDR3-1333 PC3-10600 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. DDR3-1333 runs at 1333MT/s (1333MHz data rate) for 10.6 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 128GB 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 DDR3-1333 RDIMM is used
DDR3-1333 RDIMM is commonly paired with Intel Xeon 5600-series (Westmere-EP) and first-generation Xeon E5 servers. On this page the system-matched listings cover Dell, Cisco UCS and Apple Mac Pro. Every part carries the OEM part number it replaces, so a DDR3-1333 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 DDR3-1333 module in a platform rated for a slower speed clocks down to the platform's speed; a slower module in a DDR3-1333 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.
