128 GB of DDR4 2933 ECC registered memory in a 2 x 64 GB kit for HP SimpliVity 325 Gen10 servers
Capacity 128GB (2 x 64GB)
This 128GB kit consists of two 64GB DDR4 2933 ECC registered DIMMs built for the HP SimpliVity 325 Gen10. Each module runs at 1.2V with CL21 latency and a 2Rx4 organisation. The registered design adds a buffer for signal integrity in multi-DIMM server configurations.
The kit substitutes HP part numbers including P19045-K21, P19045-B21, P00930-H21 and related SKUs. It is also backward compatible with 2133, 2400 and 2666MHz bus speeds, so it can fill slots in systems originally populated with slower modules. The upgrade is worth it when the platform requires registered ECC memory and the existing capacity limits virtual-machine density or in-memory database performance.
Two 64GB modules deliver 128GB of ECC protected memory, supporting large virtualisation clusters, heavy container deployments and memory-intensive analytics. The registered architecture scales across all populated channels without signal degradation. Buyers who need load-reduced DIMMs, unbuffered ECC, or capacities beyond 128GB per two-module kit cannot use this product.

Yes, the 288-pin DDR4 ECC registered DIMM is built for the HP SimpliVity 325 Gen10 and matches its registered memory slot layout.
Populate the two modules in matching channel pairs as shown in the HP SimpliVity 325 Gen10 service guide; the step often missed is seating each DIMM until both ejector clips click.
Replace the modules when the system management log shows a sustained increase in correctable ECC errors, indicating cell wear on the 2Rx4 DDR4 2933 chips.
