System-specific DDR5 RDIMM for HP Alletra

This OWC module delivers 128 GB of DDR5 ECC registered memory in a single 288-pin DIMM. It runs at 5600 MT/s with CL46 latency at 1.1 V and is validated for HP Alletra 4110 and 4120 storage servers.

Suited for Alletra 4110 and 4120 expansion

Administrators expanding capacity in those exact platforms can install this stick without mixing concerns. Builders working on standard desktops, consumer workstations or any system that requires unbuffered or load-reduced DIMMs must choose a different module type.

128 GB per slot with registered ECC integrity

One module fills a slot with maximum density for the supported platforms, providing error correction and signal buffering for heavy storage workloads. Systems needing more total memory must populate additional slots, while boards limited to lower-rank DIMMs cannot use this 4Rx4 design.

Questions about this item

Does this 288-pin DDR5 RDIMM require an HP Alletra 4110 or 4120 server to operate?

Yes — the module is validated for HP Alletra 4110 and 4120 systems and will not work in standard desktop computers.

Can I mix this 4Rx4 ECC registered module with unbuffered or load-reduced DIMMs already installed in my Alletra?

No — registered memory cannot be mixed with unbuffered or load-reduced modules; all slots must use identical registered ECC DIMMs.

After installation, how do I confirm the module is running at DDR5 5600 with CL46 latency?

Check the system BIOS or iLO interface — it will report the module speed as 5600 MT/s and CAS latency 46 when configured correctly.
