Eight green circuit boards with black memory chips and gold edge connectors

OWC

OWC 2TB (8×256GB) DDR4 2933 PC4-23400 CL21 8Rx4 288-pin 1.2V ECC LRDIMM memory upgrade

SKU CH-MP3Q-CDQR5

Eight 256 GB DDR4 2933 ECC load-reduced DIMMs totalling 2 TB for Dell PowerEdge R840 and R940xa servers

Capacity 2TB (8 x 256GB)

  • 2TB total capacity scales server workloads with eight 256GB modules
  • 2933MHz DDR4 speed and CL21 latency boost data throughput
  • ECC load-reduced design protects data integrity in critical systems
  • JEDEC and RoHS compliant for warranty-safe upgrades
  • Backward compatible with 2133, 2400 and 2666MHz platforms

OWC 2 TB DDR4 LRDIMM Kit

This kit provides 2 TB of DDR4 memory across eight 256 GB modules running at PC4-23400 2933 MHz CL21. Each module is a 288-pin ECC Load Reduced DIMM operating at 1.2 V. It is designed for server and workstation platforms that require registered ECC LRDIMM technology.

Suited for Dell PowerEdge R840 and R940xa upgrades

The modules are validated for the Dell PowerEdge R840 and R940xa. They will not work in standard desktop computers and cannot be mixed with unbuffered or registered ECC memory. Buyers who need consumer DIMMs or smaller capacities should look at different memory types.

Verify your system accepts 8Rx4 LRDIMMs

Confirm that the motherboard supports 8Rx4 Load Reduced DIMMs at 2933 MHz and that all eight slots can be populated. The kit is backward compatible with 2133, 2400 and 2666 MHz operation. Check the server documentation for maximum supported capacity per slot and per channel.

Questions about this item

Will the 288-pin DDR4 LRDIMM kit work in my Dell PowerEdge R840 or R940xa?

The kit is validated for the PowerEdge R840 and R940xa. It runs at 2933MHz CL21 and will down-clock to 2666MHz, 2400MHz or 2133MHz if the platform requires it.

How does this ECC Load Reduced memory behave alongside older DDR4 modules?

It cannot be mixed with unbuffered or ECC registered DIMMs. All slots must use the same LRDIMM type for the system to operate correctly.
