HPE DDR5 4800 ECC RDIMM Server Memory

This 128GB registered DDR5 module operates at 4800MHz with CL40 latency and 1.1V voltage. It uses a 4Rx4 rank configuration and 288-pin form factor for HPE server compatibility. The ECC registered design targets data integrity in enterprise workloads.

DDR5 4800 Interface Practical Limits

DDR5 4800 delivers 38400 MB/s peak bandwidth per module. Registered buffering adds one clock cycle of latency versus unbuffered memory. The 1.1V operating voltage reduces power draw compared to earlier DDR generations. Mixed-speed populations will downclock to the slowest installed module.

128GB 4Rx4 Capacity Constraint

A single 128GB 4Rx4 module occupies one DIMM slot but presents four logical ranks to the memory controller. Platforms limited to eight ranks per channel can only populate two such modules per channel. Systems requiring higher densities per slot or lower rank counts for maximum channel population should evaluate alternative configurations.

Otázky k tomuto produktu

Should I pick the 128 GB module or combine smaller DIMMs to reach the same capacity?

This listing is a single 128 GB stick, so one module fills one slot and delivers the full capacity.

What does the 4800 MT/s rating mean for actual throughput in my server?

The module runs at DDR5 4800, giving a peak transfer rate of PC5 38400 MB/s when the platform supports that speed.

Is the 288-pin RDIMM interface compatible with standard DDR5 server boards, and does the 4Rx4 rank limit how many I can install?

It uses the 288-pin DDR5 RDIMM form factor with 4Rx4 organisation; population limits depend on the specific HPE server memory controller.
