128GB DDR5 5600 ECC RDIMM for HP/HPE Servers

This 128GB registered DDR5 module targets administrators upgrading HP or HPE systems that require part numbers P53628-0A1 or P65257-001. It delivers error-correcting code protection and registered signalling for stable operation in multi-socket server and workstation platforms.

DDR5 5600 registered DIMM constraints

The module runs at 5600 MT/s with a CAS latency of 40 at the standard 1.10V DDR5 voltage. As a 4Rx4 3DS/TSV registered DIMM it presents four logical ranks per channel, so the memory controller must support that rank depth and the system board must provide 288-pin DDR5 slots with registered-buffer capability.

Upgrading from lower-capacity DDR5 RDIMMs

Replacing smaller DDR5 registered modules with this 128GB unit increases per-slot density, reducing the number of occupied slots needed for a given total memory footprint. The jump is worthwhile when the platform’s qualified vendor list includes 4Rx4 3DS parts and the workload benefits from fewer ranks spread across more channels.

Questions about this item

Should I pick the single 128GB module or look for a kit?

This listing is a single 128GB DDR5 5600 ECC RDIMM. Add multiple modules to fill the channels your server manual recommends.

What does the 5600MHz rating deliver in my server?

The module runs at DDR5 5600 with CL40 latency and 1.10V, giving your platform the rated PC5-44800 bandwidth when installed in a supported slot.

How does the 288-pin DDR5 RDIMM interface limit speed or capacity?

The 288-pin registered DDR5 form factor carries the 5600MHz signal and 4Rx4 organisation; maximum speed and total capacity are set by your server's memory controller and qualified vendor list.
