8GB DDR3L 1333MHz ECC Registered Server Module

This single 8GB DDR3L module runs at 1333MHz with CL9 latency and 1.35V operation. It uses a 240-pin DIMM form factor and includes ECC with registered buffering for error correction and signal stability in server platforms.

Suited for HP systems referencing the listed part

The module matches HP part numbers including 500662, 604502, 604506, 606425, 606427, 647650, 647877 and 647897. It is not for desktop boards that require unbuffered non-ECC memory or for platforms that only support higher-voltage DDR3 at 1.5V.

Fits 240-pin DDR3 slots

The registered design places a register between the DRAM and the memory controller, reducing electrical load on the bus. This frees the platform to populate more slots per channel while the low 1.35V draws less power than standard DDR3.

Questions about this item

What server slot and voltage must my system provide for this DDR3L 1333 MHz 1.35 V 240-pin RDIMM to operate?

Your server needs a DDR3 240-pin DIMM slot that supplies 1.35 V and supports registered ECC modules at 1333 MHz.

Will this 2Rx4 CL9 registered ECC module run with my existing 1Rx8 CL9 DDR3L RDIMMs in the same channel?

Mixing 2Rx4 and 1Rx8 registered ECC DIMMs is often supported but depends on the server BIOS; populate identical ranks per channel for best stability.

How can I confirm the module is detected at DDR3-1333 CL9 with ECC active after installation?

Check the BIOS memory information or run a tool such as dmidecode or CPU-Z to verify speed 1333 MT/s, CAS 9, and ECC enabled.
