HPE 8GB 1Rx8 DDR4-3200 CAS-22 RDIMM SmartMemory Kit

DDR4-3200 is the faster end of DDR4, and the HPE P07525-B21 brings it in an 8GB single-rank module. It is a registered ECC DIMM with a CAS latency of 22 in HPE's SmartMemory line.

Three option numbers are listed for this memory: P07525-X21, P07525-H21 and P07525-K21. When a supplier quotes one of those, it refers to the same memory family, so you can use them when cross-checking offers.

A small capacity at a high speed fits servers that value bandwidth through many populated channels over raw capacity. It is also useful for like-for-like replacement of a failed DIMM in a ProLiant server that runs 3200 MT/s modules.

Before ordering, confirm that your processors support the speed, and that you are not mixing it with slower modules, which would pull the whole server down to the lower rate.

Available new or refurbished, each with a choice of 1 year or 3 years of warranty. No used offer is listed. Your RFQ for P07525-B21 should note how many channels you are filling.
