Server DDR3 ECC RDIMM

This A-Tech module delivers 16GB of registered ECC memory for server and workstation platforms that require DDR3 1333MHz operation. The single 240-pin DIMM uses a 2Rx4 organisation and runs at the standard 1.50V DDR3 voltage.

Registered ECC with 2Rx4 layout

The registered buffer and ECC circuitry allow the memory controller to address the full 16GB capacity while correcting single-bit errors, a requirement for many multi-socket and mission-critical systems. The 2Rx4 rank configuration determines how the chipset interleaves access across the module.

Fills one 240-pin DDR3 slot

Installation occupies a single registered DIMM slot on a compatible DDR3 server board, leaving remaining slots available for further capacity expansion. The module is validated as a direct replacement for the listed Samsung part numbers, so it fits existing qualified-memory lists without additional qualification steps.

Questions about this item

Will 16GB at 1333MHz run at that speed in my server?

The module is rated for 1333MHz PC3-10600; actual speed depends on the server's memory controller and populated slots.

What does the registered ECC design do for data integrity?

Registered buffering reduces electrical load on the memory bus, and ECC corrects single-bit errors to prevent data corruption.

Does the 240-pin DIMM fit standard DDR3 server slots?

Yes, it uses the 240-pin DDR3 DIMM form factor used by compatible server and workstation motherboards.
