Capacity 128GB (4 x 32GB)

  • 128GB kit expands server capacity with four 32GB modules
  • DDR5 4800 speed raises bandwidth for demanding workloads
  • ECC registered design protects data integrity in critical applications
  • 1V operation reduces power draw per module
  • Validated for HP ProLiant Gen11 DL385 DL560 DX360 DX365 ML350

Target server upgrade

This OWC kit provides 128 GB of DDR5 ECC registered memory in four 32 GB modules. It is built for HP ProLiant DL385 Gen11, DL560 Gen11, DX360 Gen11, DX365 Gen11 and ML350 Gen11 servers that require registered DIMMs with error correction.

Compatibility limits

The modules are registered ECC RDIMMs and will not work in standard desktop computers or in systems that only accept unbuffered or load-reduced memory. Buyers who need non-ECC consumer DIMMs or a different form factor should look at something else.

Deciding specification

The memory runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1 V in a 288-pin 2Rx8 registered layout. This exact speed, voltage and registered ECC combination determines whether the kit matches the server's qualified vendor list.

Questions about this item

What does the 4800 MT/s rating deliver in a ProLiant Gen11 server?

The kit runs at DDR5-4800 with CL40 timing and 1.1 V, providing the JEDEC-standard data rate the Gen11 memory controller expects for registered ECC operation.

How does the PC5-38400 designation limit real-world throughput?

PC5-38400 is the JEDEC peak transfer rate for DDR5-4800; actual bandwidth depends on the server's memory-channel population and BIOS configuration.

Will the 288-pin RDIMMs fit the HP ProLiant DL385 Gen11 DIMM slots?

Yes — the modules are 288-pin DDR5 ECC registered DIMMs built to the exact form factor required by the DL385 Gen11 and the other listed Gen11 models.
