DDR3 ECC RDIMM server module

A 4 GB DDR3 1333 MHz ECC registered DIMM built as a compatible replacement for Samsung M393B5170GB0-CH9Q9 and M392B5170EM1-CH9 modules. It runs at PC3-10600 speed with CL9 latency and standard 1.5 V operation. The 2Rx4 organisation and Samsung chipset suit server and workstation platforms that require registered ECC memory.

Who this suits and who should look elsewhere

Designed for administrators upgrading or repairing servers and workstations that specifically call for DDR3 1333 registered ECC DIMMs. Not for desktop boards that accept only unbuffered non-ECC memory, nor for systems that need a different DDR generation or higher capacities per slot.

The specification that decides fit

The module is a 240-pin DDR3 registered ECC DIMM operating at 1.5 V with 2Rx4 rank configuration; the motherboard must support registered ECC DDR3 at 1333 MHz to use this part.

Questions about this item

Does this module fit a standard 240-pin DDR3 DIMM slot?

Yes, the stick is a 240-pin DDR3 DIMM designed for server and workstation boards that accept registered ECC memory.

What is the correct seating procedure for the registered ECC module?

Align the notch with the slot key, press down firmly until both retention clips click, and verify the module sits evenly; the registered buffer adds height so extra pressure is often needed.

Will the Samsung chipset on this RDIMM require a firmware update later?

The Samsung chipset is fixed in hardware; no firmware updates apply to the memory module itself.
