This page lists DDR4-2933 PC4-23400 Load-Reduced DIMM (LRDIMM) — 288-pin, 1.2V, ECC, with a data buffer that reduces electrical load on the memory controller so the highest capacities per channel stay stable. DDR4-2933 runs at 2933MT/s (2933MHz data rate) for 23.4 GB/s of bandwidth per channel.

What is on this page

Single modules from 64GB to 256GB (64GB, 128GB and 256GB), in 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 DDR4-2933 LRDIMM is used

DDR4-2933 LRDIMM is commonly paired with second-generation Intel Xeon Scalable (Cascade Lake) platforms — Dell PowerEdge 14G, HPE ProLiant Gen10, Lenovo ThinkSystem and the 2019 Apple Mac Pro. On this page the system-matched listings cover Supermicro, Dell, HPE, Cisco UCS and Apple Mac Pro. Every part carries the OEM part number it replaces, so a DDR4-2933 order written against a Dell, HPE, Lenovo, Cisco or Supermicro part number can be matched line for line.

Choosing the right LRDIMM module

LRDIMM is for maximum capacity per channel, not maximum speed. It cannot be mixed with RDIMM, and every LRDIMM in a channel should match capacity and rank. Choose DDR4-2933 LRDIMM when the platform's supported maximum needs 64GB, 128GB or 256GB modules in every slot; for smaller totals, DDR4-2933 RDIMM is usually the better fit. If you are unsure, send us the system model or the OEM part number and we will confirm fitment before you order.
