HPE 64GB 2Rx4 DDR4-2933 RDIMM SmartMemory Kit

P19045-B21 is HPE's kit for adding 64 GB of dual-rank DDR4-2933 RDIMM memory, with a CAS latency of 21. HPE lists the ProLiant DL325 Gen10 as the compatible system, so that is the server to check it against.

A 2Rx4 RDIMM is a registered module with two ranks, the usual choice when you want 64 GB per slot without moving to a load-reduced design. Memory of this size is often used to build large virtualization hosts on a single-socket platform.

Single-socket DL325 Gen10 servers are often built as virtualization or storage hosts where memory is the main constraint, so a 64 GB module is a practical building block for that platform.

Only new and refurbished units are listed, both with a 1 year or 3 years warranty.
