4GB DDR3 1333MHz ECC RDIMM

This A-Tech module is a 4GB DDR3 1333MHz PC3-10600 ECC Registered DIMM built as a compatible replacement for the Kingston KTM-SX313L/4G. It operates at 1.5V with CL9 latency and a 2Rx4 rank configuration on a 240-pin form factor. The unit is designed for server and workstation platforms that require registered ECC memory. Quality assurance testing is performed on every module before shipment.

Suited for registered ECC DDR3 servers

This memory suits administrators upgrading or repairing servers and workstations that specifically call for DDR3 1333MHz ECC RDIMM modules with a 2Rx4 organisation. It will not work in systems that accept only unbuffered non-ECC UDIMMs, nor in platforms that require a different DDR generation, voltage, pin count or rank arrangement. Buyers who need higher capacities, faster speeds or a different rank layout should look at other modules.

Registered ECC with 2Rx4 organisation

The defining specification is the Registered ECC design combined with a 2Rx4 rank structure, which determines whether the system's memory controller can address this module. Compatibility depends on the platform supporting DDR3 1333MHz registered operation at 1.5V with this exact rank geometry. Always verify the motherboard or server documentation for supported memory configurations before purchasing.

Questions about this item

Does the 4GB DDR3 1333MHz ECC RDIMM ship as a single 240-pin module or do I need to buy anything else?

The listing supplies one 4GB 240-pin DDR3 ECC registered DIMM; no additional parts are required for installation.

Should I choose the 2Rx4 4GB stick or look for a different capacity for my server?

This module is a single 4GB 2Rx4 registered DIMM; select it when your system needs exactly one 4GB ECC RDIMM at DDR3 1333 speed.

What does the PC3-10600 rating mean for real-world throughput in my machine?

PC3-10600 indicates a peak transfer rate of 10600 MB/s at 1333 MT/s, giving typical server workloads the bandwidth this DDR3 ECC RDIMM is rated for.
