HPE 256GB 4Rx4 DDR5-4800 3DS RDIMM SmartMemory Kit

P90550-B21 offers 256 GB on a 4Rx4 3DS RDIMM at DDR5-4800 with ECC and a CAS latency of 60. It is listed for the ProLiant DL360 Gen11 and DL380 Gen11.

This is the entry-speed version of the 256 GB module for those servers, which can be an advantage if a lower rated speed is acceptable and capacity is the priority.

If you need a higher memory speed for the same servers, mention it in your request and we can quote the faster 256 GB part instead. Only the DL360 Gen11 and DL380 Gen11 are named, so other models would need a different module. Pairing identical modules across the memory channels keeps the configuration simple to support.

Choose between new and refurbished; both carry a 1 year or 3 years warranty.
