8GB DDR3L ECC RDIMM for Servers

This 8GB registered DIMM runs at DDR3L 1333 (PC3L-10600) with CL9 latency and 1.35V low-voltage operation. It uses a 2Rx4 organisation and major-brand chips to deliver error-correcting memory for server and workstation workloads. The module is a direct replacement for HP part numbers 605313-07H, 687461-001, 647897-S21, 647877-B21 and 605313-171.

Check DDR3L RDIMM support before ordering

Verify that your system accepts DDR3L registered ECC DIMMs at 1.35V and 240-pin form factor. Registered modules will not work in platforms that require unbuffered memory, and low-voltage DDR3L may not be compatible with standard 1.5V-only slots. Confirm the maximum supported capacity per slot and total system limit in your hardware documentation.

Fits 240-pin DDR3L server slots

The module installs in a standard 240-pin DIMM socket and draws 1.35V, reducing power draw compared with 1.5V DDR3. Registered buffering lightens the electrical load on the memory controller, allowing larger configurations in multi-socket boards. ECC capability corrects single-bit errors to maintain data integrity in critical applications.

Questions about this item

Does the module arrive alone or with extra parts such as a heatsink or installation tool?

The listing describes a single 8 GB DDR3L 1333 MHz ECC registered DIMM; no heatsink, tool or additional accessories are included.

Should I pick this 8 GB 2Rx4 stick or look for a different capacity or rank?

This stick provides 8 GB in a dual-rank 2Rx4 organisation; choose it when your server needs exactly that capacity and rank, otherwise select a module matching your system's qualified list.

What does the PC3L-10600 rating mean once the DIMM is installed in a server?

PC3L-10600 indicates DDR3L 1333 MT/s at 1.35 V with ECC and registered buffering, giving standard server bandwidth and error correction for compatible platforms.
