Server-grade ECC LRDIMM kit

This OWC kit delivers 1TB of DDR4 3200 memory across eight 128GB LRDIMM modules. It targets administrators upgrading Dell PowerEdge R6525, R750xa or R7525 servers that require registered ECC memory. The load-reduced design reduces electrical load on the memory controller, allowing higher densities per channel. Desktop workstations and consumer motherboards cannot use these modules.

Capacity headroom at 3200 MT/s

The eight-module configuration fills all slots on supported dual-socket platforms, providing maximum ranked capacity for virtualisation, in-memory databases or large container fleets. CL22 latency at 3200 MT/s suits throughput-oriented workloads rather than latency-sensitive tasks. Systems limited to 2133, 2400, 2666 or 2933 MT/s will down-clock automatically, reducing peak bandwidth proportionally.

Integration requirements and trade-offs

Each 288-pin module operates at 1.2V and requires a server board qualified for 4Rx4 LRDIMMs; mixing with unbuffered or standard registered DIMMs is not supported. No heat spreaders are fitted, so adequate chassis airflow must already exist. The kit frees procurement from sourcing matched single modules but consumes every available DIMM slot on the target platforms.

Questions about this item

Will the 3200MHz CL22 LRDIMMs run with my existing 2666MHz DDR4 modules in a PowerEdge R7525?

No, load-reduced ECC modules cannot be mixed with unbuffered or registered ECC memory; all slots must use identical LRDIMM type.

How can I confirm the kit is operating at 3200MHz after installing it in my R6525?

Check the system BIOS or iDRAC memory inventory; it will report each 128GB module running at 3200MHz CL22 1.2V.

Does the 1TB kit include eight 128GB sticks only, or are any tools or cables supplied?

The box contains exactly eight 288-pin 128GB DDR4 LRDIMM modules; no tools, cables or additional hardware are included.
