  • ECC load-reduced design protects data integrity in Dell PowerEdge XR11 and XR12 servers
  • 256GB kit (2 x 128GB) doubles maximum memory capacity for virtualization workloads
  • DDR4 3200 CL22 at 1.2V delivers JEDEC-standard speed with low power draw
  • 4Rx4 288-pin LRDIMM modules install without mixing buffered or unbuffered memory types
  • Backward compatible with 2133, 2400, 2666 and 2933MHz systems for flexible deployment

Server memory kit

This OWC kit supplies 256 GB of DDR4 ECC Load Reduced DIMMs in a matched pair of 128 GB modules. It is built for Dell PowerEdge XR11 and XR12 servers that require registered, error-correcting memory. Standard desktop boards cannot use these modules.

Sustained operation

Load Reduced topology lowers electrical load on the memory controller, allowing the 4Rx4 organisation to run at 3200 MT/s CL22 without throttling during long compute runs. The 1.2 V operating voltage keeps power draw stable across extended workloads. Backward compatibility with 2133, 2400, 2666 and 2933 MT/s buses lets the kit slot into existing configurations at the highest common speed.

Upgrade path

The kit replaces lower-capacity LRDIMM sets or fills empty slots to reach the 256 GB total in two modules. It cannot be mixed with unbuffered or standard registered ECC DIMMs, so the full population must use the same Load Reduced type. The jump is worthwhile when the server hits memory limits on virtualization, database or analytics tasks and the platform supports 128 GB density per slot.

Questions sur cet article

How much power does the 1.2 V DDR4 3200 LRDIMM draw when the server runs all day?

Each 128 GB module operates at 1.2 V DDR4 3200 CL22; total kit capacity is 256 GB across two LRDIMMs.

What must the system already support for this ECC load-reduced kit to function?

The motherboard must accept 288-pin DDR4 ECC LRDIMM modules at 1.2 V and support 4Rx4 registered memory; it cannot mix with unbuffered or standard registered DIMMs.

Will these 3200 MHz modules work in a Dell PowerEdge XR11 that currently runs 2400 MHz memory?

Yes — the kit is backward compatible with 2133, 2400, 2666 and 2933 MHz speeds and will downclock to match the existing bus.
