OWC 128GB (2x64GB) DDR4 2933 ECC RDIMM CL21 1.2V 2Rx4 HP Apollo 4200 6500 Gen10

OWC 128GB DDR4 ECC RDIMM Kit

This 128GB kit contains two 64GB DDR4 2933 ECC Registered DIMMs built for HP Apollo 4200 Gen10 and 6500 Gen10 servers. It targets administrators who need to expand memory capacity in those specific platforms. The modules are not compatible with standard desktop computers or unbuffered memory configurations.

Straightforward Server Installation

Each 288-pin RDIMM seats in the Apollo DIMM slots like any registered module; no special tools are required. The most common issue is mixing these registered DIMMs with unbuffered or load-reduced memory, which the platform does not support. Verify that all populated slots use identical registered ECC modules before powering on.

128GB Registered Capacity for Apollo Gen10

The dual-rank 2Rx4 organisation delivers 128GB total at 1.2V, running at 2933MT/s with CL21 latency and falling back to 2666, 2400 or 2133MT/s when the system requires it. This capacity handles large virtualisation workloads and in-memory databases; it reaches its limit when the chassis DIMM slots are fully populated or the workload demands memory speeds beyond the DDR4 2933 specification.
