HPE-Compatible DDR5 ECC RDIMM

This 64GB registered DDR5 module is built for HPE servers and workstations that require ECC protection. It delivers 4800 MT/s bandwidth with CL40 latency and operates at 1.1V. The 2Rx4 organization and 288-pin form factor match the P50312-B21 specification for direct replacement.

Registered DDR5 interface limits

Registered DIMMs add a clock cycle of buffering that stabilises heavy loads but prevents use in unbuffered consumer platforms. The DDR5 4800 standard caps this module at PC5-38400 throughput, so systems wired for higher DDR5 speeds will down-clock to this rate. ECC functionality requires a motherboard that exposes the extra parity lane.

Single 64GB 2Rx4 module

One dual-rank 64GB stick fills a single slot, making it the right part when the board has limited DIMM positions or when the memory controller requires 2Rx4 density for full-channel population. Buyers needing lower-capacity sticks or unbuffered ECC should look elsewhere.

Questions about this item

Is this a single 64GB module or a kit of multiple sticks?

It is a single 64GB module, so you add capacity in 64GB increments per slot.

What does the 4800 speed rating mean for actual throughput in a server?

The module runs at DDR5 4800 with CL40 timing; actual throughput depends on the memory controller and channel population.

Does the 288-pin RDIMM interface limit the maximum speed I can reach?

The 288-pin DDR5 RDIMM form factor is built for the 4800 spec; the platform's memory controller determines the final operating speed.
