Server memory kit

This OWC kit provides 1TB of DDR5 ECC Registered RDIMM capacity across eight 128GB modules rated at 4800 MT/s with CL40 latency. It is built for Dell PowerEdge R6625, R760, R7615 and R7625 servers that require registered error-correcting memory.

Compatibility check

Verify that each target server supports 4Rx4 registered DDR5 DIMMs at 1.1V and has eight free 288-pin slots available. Registered modules cannot be mixed with unbuffered or load-reduced memory in the same system.

Upgrade path

The kit replaces lower-capacity or slower DDR5 RDIMM sets when workloads demand maximum registered memory per channel. The jump is worth it when virtualisation density or in-memory databases exceed the limits of smaller module configurations.

Questions about this item

What comes in the 1 TB kit and is anything else required to install it?

The kit contains eight 128 GB DDR5 4800 CL40 4Rx4 288-pin 1.1 V ECC registered RDIMM modules. No extra parts are needed for installation in compatible Dell PowerEdge servers.

Why choose the 1 TB 8 x 128 GB version instead of a smaller capacity?

This version delivers the maximum 1 TB capacity using eight 128 GB modules, fully populating eight memory slots for the highest density supported by the listed PowerEdge models.

What does the DDR5 4800 CL40 rating mean for real-world server performance?

It provides JEDEC-standard 4800 MT/s throughput with CL40 latency and on-die ECC, giving registered error correction and maximum bandwidth for the supported R6625, R760, R7615 and R7625 platforms.
