Server-grade DDR4 kit

This OWC kit delivers 512 GB across four 128 GB DDR4-3200 ECC load-reduced DIMMs. It is built for Dell PowerEdge MX750c, R650 and R750 servers that require registered memory with error correction. The modules run at 1.2 V with CL22 latency and a 4Rx4 organisation.

Build integration

Each 288-pin LRDIMM fits the registered memory slots in the listed PowerEdge platforms and cannot be mixed with unbuffered or standard registered DIMMs. The load-reduced design lowers electrical load on the memory controller, allowing the full 512 GB capacity to be populated across available channels. Backward compatibility with 2133, 2400, 2666 and 2933 MHz buses lets the kit run in systems configured for lower speeds.

Who this suits

Ideal for administrators expanding memory in compatible Dell PowerEdge servers or building new configurations that demand maximum registered ECC capacity. Not suitable for standard desktop motherboards, workstations that require unbuffered or standard registered DIMMs, or any system that does not support load-reduced DDR4 modules.

Questions about this item

Will the 288-pin DDR4 3200 CL22 LRDIMM kit run at full speed in a Dell PowerEdge R750?

The kit is tested for Dell PowerEdge R750, R650 and MX750c and meets JEDEC DDR4 3200 PC4-25600 CL22 specifications for those platforms.

How much power does the 4Rx4 1.2V load-reduced ECC kit draw under sustained server loads?

Each 128 GB module operates at 1.2 V; the load-reduced buffer reduces electrical load on the memory bus compared with standard registered DIMMs.

What existing memory configuration must the Dell PowerEdge already have to add this 4 × 128 GB kit?

The server must support DDR4 ECC LRDIMM and cannot mix these modules with unbuffered or registered ECC DIMMs.
