16 GB DDR3-1333 ECC RDIMM

This 16 GB DDR3-1333 ECC registered DIMM runs at 1.35 V and is built for HP Gen 8 servers. It targets administrators who need validated, low-voltage memory for mission-critical workloads.

Capacity and headroom

A single module delivers 16 GB at 1333 MHz, PC3-10600, with ECC and registered signal processing for data integrity under sustained load. Systems limited to DDR3-1333 speeds or 1.35 V operation will run at the rated specification; faster or higher-voltage platforms will down-clock to match.

Upgrade context

It replaces lower-capacity DDR3 RDIMMs or non-ECC modules in compatible HP Gen 8 platforms where registered ECC memory is required. The jump is worthwhile when expanding total memory beyond existing limits or when correcting errors that unbuffered non-ECC memory cannot detect.

Questions about this item

Will the 1.35 V DDR3-1333 module run reliably alongside existing 1.5 V DDR3 DIMMs in my HP Gen 8 server?

The module operates at 1.35 V; when mixed with 1.5 V DIMMs the memory controller typically raises voltage to the higher level, so all installed sticks will run at 1.5 V and the lowest common speed.

How can I verify the 16 GB ECC registered DIMM is detected and correcting errors after installation?

Check the POST memory count and the iLO or BIOS health log — both should show 16 GB per module with ECC active and zero correctable errors reported.

Does the 647883-B21-AX box contain only the memory module or are any cables or brackets included?

The package contains the single 16 GB DDR3-1333 RDIMM; no cables, brackets or additional hardware are supplied.
