System-specific server upgrade

This OWC kit supplies 256 GB of DDR4 ECC registered memory in four 64 GB modules. It is built for the HP SimpliVity 325 Gen10 and is intended for administrators expanding capacity in that platform.

Verify registered ECC requirement

The modules are registered ECC RDIMMs and will not work in systems that require unbuffered or load-reduced DIMMs. Confirm the SimpliVity 325 Gen10 accepts registered memory and that all four slots can be populated with 2Rx4 parts before ordering.

Standard 288-pin RDIMM form factor

Each stick uses the 288-pin DDR4 registered layout without a heat spreader, running at 1.2 V. The design fits the server’s DIMM slots directly and operates within JEDEC electrical limits for daily enterprise workloads.

Perguntas sobre este artigo

What does the 256GB kit include and is anything else required?

The kit contains four 64GB DDR4 2933 ECC Registered RDIMM modules (part 2R9D42R4256S). No additional components are needed for installation in a compatible HP SimpliVity 325 Gen10 server.

Why choose the 256GB (4x64GB) CL21 2Rx4 version over other capacities?

This configuration provides 256GB total using four dual-rank 64GB modules at CL21 latency, matching the HP part numbers P19045-K21, P00930-H21, P14636-001 and others listed for the SimpliVity 325 Gen10.

What does the 2933MHz rating mean once installed in the SimpliVity 325 Gen10?

The modules run at DDR4 2933 (PC4-23400) with CL21 timing at 1.2V. They are backward compatible with 2133MHz, 2400MHz and 2666MHz bus speeds if the system requires a lower frequency.
