HPE 32GB 2Rx8 DDR5-4800 CAS-40 UDIMM Standard Memory Kit

P64339-B21 gives 32 GB on a dual-rank (2Rx8) DDR5-4800 UDIMM with CAS 40. It belongs to HPE's Standard Memory line for systems that take unbuffered modules.

If your records use P64634-001, that is the spare version of the same module, so either number leads here.

32 GB UDIMMs let smaller servers and workstations reach memory totals that used to need registered modules, as long as the platform supports them.

Single orders and batches are handled the same way: list the quantity in your RFQ and we confirm availability for each condition. This is a UDIMM, so it is not meant to sit alongside registered modules in the same server.

Available new, refurbished or used. Warranty is 1 year or 3 years for new and refurbished, and 90 days for used.
