Server-grade ECC RDIMM upgrade

This OWC kit provides 128GB of DDR4 2933 CL21 registered memory in two 64GB modules. It is built for HP ProLiant Gen10 servers including the BL460c, DL325, DL360, DL380 and DL385. The modules operate at 1.2V and carry ECC with registered buffering for data integrity in multi-socket workloads.

Registered buffering and ECC change compatibility

The 2Rx4 registered DIMMs cannot be mixed with unbuffered or load-reduced memory in the same system. Backward compatibility with 2133, 2400 and 2666MHz speeds allows the kit to run in slots rated for those lower frequencies. No heat spreaders are fitted, so airflow clearance follows the server chassis design.

128GB capacity for virtualisation density

Two 64GB ranks deliver high density per channel, letting the listed Gen10 platforms host more virtual machines or larger in-memory databases. The ceiling is the server's maximum supported memory per socket and total slot count, which vary by model. Workstations or desktops that require unbuffered non-ECC DDR4 cannot use this kit.

Perguntas sobre este artigo

Will the 64GB RDIMM modules need a heat spreader added later for sustained server loads?

No heat spreader is included on these 2Rx4 modules; they rely on chassis airflow at the rated 1.2V for cooling.

What speed limit appears first when the kit runs continuously at DDR4 2933 CL21?

The CAS latency of 21 cycles at 2933 MT/s sets the timing ceiling under sustained operation.

How much power and heat does the 128GB kit produce when running all day in a ProLiant DL380 Gen10?

Each 64GB module operates at 1.2V without a heat spreader, so total draw and thermals stay within standard RDIMM limits for the platform.
