128GB DDR5-4800 ECC RDIMM for HPE servers

This 128GB DDR5-4800 module uses a 4Rx4 ECC registered design built for HPE server platforms. It delivers 38400 MT/s bandwidth and targets administrators who need maximum capacity per slot. The part matches HPE PN P46972-H21 and carries a lifetime warranty from Brute Networks.

DDR5-4800 registered limits

DDR5-4800 registered DIMMs operate at the JEDEC base data rate and require a memory controller that supports 4Rx4 load profiles. Total system capacity and maximum DIMM count depend on the specific server model and BIOS revision, not on the module alone. Mixed-rank populations may reduce the effective speed below 4800 MT/s on some platforms.

Verify HPE server qualification

Confirm the exact HPE server model appears on the vendor qualification list for PN P46972-H21 before ordering. Check that the BIOS version supports 128GB 4Rx4 registered modules at the full 4800 MT/s rate. Ensure the memory channel population rules for your chassis allow the desired quantity of these DIMMs.

Questions about this item

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

Choose the 128GB module when your workload needs maximum density per slot; the 4Rx4 organisation delivers that capacity in a single registered DIMM.

What does the 4800 MT/s rating actually deliver once the module is installed in a live system?

The module runs at DDR5-4800, providing up to 38400 MB/s of peak bandwidth per DIMM when the platform operates at the rated speed.

Is the DDR5 interface on this RDIMM limited by any specific standard or platform cap in practice?

The DDR5 interface follows the PC5-38400 specification; actual throughput is governed by the memory controller and BIOS of the HPE-compatible server it is installed in.
