Server ECC RDIMM upgrade

This OWC module is an 8GB DDR3 1333 PC3-10600 CL9 registered DIMM built for servers and workstations. It runs at 1.5V with ECC and a 2Rx4 rank layout on a 240-pin interface. The part is fully JEDEC and ROHS compliant and matches HP part numbers 593913B21, A0R56A, FX622AA and FX622UT.

Who this suits and who it does not

It suits administrators upgrading or repairing HP ProLiant or compatible enterprise platforms that require registered ECC memory. It will not work in standard desktop or consumer laptops that accept only unbuffered non-ECC modules, and it cannot be mixed with unbuffered DIMMs in the same system. Builders needing unbuffered memory or a different voltage should look elsewhere.

Build integration notes

The module fits 240-pin DDR3 slots wired for registered ECC operation and draws 1.5V from the memory bus. No heat spreader is included, so airflow across the DIMM rows must be provided by the chassis. Matching capacity, speed and manufacturer across all populated slots is recommended for optimal stability.

Questions about this item

Will this 240-pin DDR3 ECC RDIMM work in my standard desktop motherboard?

No, this registered ECC module is built for workstations and servers and will not function in consumer desktop boards that require unbuffered memory.

Can I add this 8GB CL9 1.5V stick alongside the unbuffered DDR3 modules already in my server?

Registered and unbuffered memory cannot be mixed; all installed DIMMs must be registered ECC for the system to operate correctly.

How do I confirm the module is running at DDR3 1333 CL9 after installation?

Check the BIOS memory information or an OS utility such as dmidecode or CPU-Z; they should report 1333 MT/s, PC3-10600 and CAS latency 9.
