64GB DDR5-4800 ECC registered RDIMM with 2Rx4 organisation for HPE P48502-001 compatible servers
This 64GB DDR5-4800 module is built for servers that require registered ECC memory. It suits administrators expanding capacity in HPE platforms using part number P48502-001. The 2Rx4 organisation delivers high density per slot. Buyers needing non-ECC or unbuffered memory for workstations should look elsewhere.
DDR5 architecture moves the power-management IC onto the module for tighter voltage control. Registered buffering reduces electrical load on the memory controller during sustained workloads. ECC operation adds a background correction pass without audible impact. No active cooling is present on the stick itself.
The RDIMM form factor fits standard DDR5 server DIMM slots keyed for registered memory. Each module occupies one slot and frees remaining channels for further expansion. Matching modules are supplied together to keep channel population identical. Systems requiring unbuffered UDIMMs or a different pin-out cannot use this part.

Align the notch on the 2Rx4 module with the slot key, press firmly until both ejector clips click shut, then verify the BIOS recognises the full 64GB at 4800 MT/s.
No routine maintenance is required; the module is covered by a lifetime warranty, so a replacement is only needed if a memory error persists after reseating.
The memory controller caps throughput at the rated 4800 MT/s PC5-38400 speed, so sustained bandwidth cannot exceed that specification.
