HPE 64GB 2Rx4 DDR5-6400 Registered Smart Memory Kit
P69728-B21 · Refurbished · 1 year warranty
HPE P69728-B21 is a Registered Smart Memory kit for the ProLiant DL380 Gen12. The kit contains 1 module of 64GB, so the part number maps directly to a single DIMM.
The module is DDR5 running at 6400 MT/s with CAS latency 52. It is a registered DIMM with a 2Rx4 rank layout, meaning two ranks built from x4 DRAM chips, and it supports ECC. The x4 layout is common on high-capacity server memory.
This kit suits DL380 Gen12 servers running virtualization, databases or analytics, where 64GB per slot keeps large memory totals within the available slots.
HPE spares use part number P71256-001 for this module. If you are replacing a failed DIMM and your service records show that number, it is the same part.
New, Refurbished and Used kits are all available. New and Refurbished carry a choice of 1 year or 3 years of warranty. Used carries 90 days. Request pricing with the number of kits you need.
