128GB DDR5-4800 ECC RDIMM

This 128GB DDR5-4800 4Rx4 ECC Registered RDIMM is built for enterprise servers and workstations that require high-density, error-correcting memory. It matches HPE part number P50313-B21 for drop-in compatibility with qualified platforms. The module targets administrators scaling memory capacity in supported systems.

DDR5-4800 registered interface limits

The DDR5-4800 registered interface operates at 4800 MT/s with a PC5-38400 bandwidth rating. Registered buffering adds one clock cycle of latency to stabilise heavy loads across many modules. ECC circuitry corrects single-bit errors and detects multi-bit faults without software intervention. Maximum usable capacity per channel depends on the platform memory controller and BIOS.

Four-rank density and headroom

The 4Rx4 organisation packs 128GB into a single dual in-line module, letting dense configurations reach large totals with fewer slots. Four ranks increase electrical loading, so the memory controller must support quad-rank DIMMs at the rated speed. Workloads that exceed the installed capacity will swap to storage, reducing throughput. Systems limited to lower rank counts per channel cannot use this module.

Questions about this item

Should I choose the 128GB 4Rx4 DDR5-4800 module or a lower capacity for my server?

The 128GB 4Rx4 DDR5-4800 module provides maximum density per slot, ideal for memory-intensive workloads; choose lower capacities only if your platform limits rank count or total memory per channel.

What does the PC5-38400 rating mean for actual performance in my system?

PC5-38400 denotes a peak transfer rate of 38400 MB/s at 4800 MT/s; real-world throughput depends on your CPU memory controller, channel population and BIOS settings.

Does the DDR5-4800 interface limit the module speed in a compatible HPE server?

The DDR5-4800 interface sets a maximum data rate of 4800 MT/s; the module will run at this speed or downclock to match the platform's supported memory frequency.
