Server memory kit

This OWC kit provides one terabyte of DDR4 ECC load-reduced memory across eight 128 GB modules. It is built for Dell PowerEdge XR11 and XR12 servers and workstations that require registered LRDIMM technology.

288-pin LRDIMM installation

Each module uses the 288-pin DDR4 form factor and operates at 1.2 V with a CL22 latency at 3200 MT/s. The load-reduced design reduces electrical load on the memory controller, allowing the full 1 TB population without mixing with unbuffered or standard registered DIMMs.

For PowerEdge XR11 and XR12 upgrades

Suitable for administrators expanding memory in compatible Dell PowerEdge XR11 or XR12 systems. Not suitable for standard desktop PCs, laptops, or any platform that does not support DDR4 ECC load-reduced DIMMs.

Questions about this item

Will the 4Rx4 128 GB modules hit the Dell PowerEdge XR11 memory-channel rank limit before I can fill all 8 slots?

Each 128 GB module is 4Rx4. The XR11 supports up to 8 ranks per channel. Two 4Rx4 DIMMs per channel reach that 8-rank ceiling, so all eight slots can be populated with this kit.

How much heat and power will the 1.2 V LRDIMM kit add when the server runs 24/7?

LRDIMMs draw slightly more power than standard RDIMMs because of the buffer chip, but at 1.2 V DDR4 the increase is modest. No heat spreader is fitted, so adequate chassis airflow is required for continuous operation.

Which Dell PowerEdge models must I already own for this 8 × 128 GB DDR4 3200 kit to work?

The kit is validated for Dell PowerEdge XR11 and XR12 only. It will not work in standard desktops and cannot be mixed with unbuffered or registered ECC memory.
