A-Tech 4GB DDR3 ECC RDIMM

This module is a 4GB DDR3 1333MHz ECC registered DIMM built as a compatible replacement for IBM-Lenovo part numbers 43X5052, 47J0151 and 49Y1440. It runs at CL9 latency and 1.5V standard voltage using a 2Rx4 organisation and major-brand chips. The 240-pin form factor fits server and workstation boards that require registered ECC memory.

Who this suits and who it does not

The part suits administrators upgrading or repairing IBM-Lenovo systems that specify the listed part numbers and demand registered ECC DDR3 at 1333MHz. Buyers whose platforms require unbuffered UDIMMs, different rank configurations or non-ECC modules cannot use this memory.

Deciding specification

The registered ECC design with 2Rx4 organisation is the single specification that determines compatibility; only systems that explicitly support registered ECC DDR3 DIMMs at this speed and rank will accept the module.

Questions about this item

Will this 1.50V DDR3 1333MHz ECC RDIMM work alongside existing registered modules in my server?

The module runs at the standard DDR3 voltage of 1.50V and is a registered ECC DIMM, matching the electrical and buffering requirements of other registered DDR3 server memory.

How can I confirm the 2Rx4 registered ECC module is recognised correctly after installation?

Check the system BIOS or UEFI memory information screen; it should show a 4GB DDR3 1333MHz registered ECC DIMM with the correct speed and ECC status.

Does the package include only the 240-pin DIMM or are any extra components supplied?

The box contains the single 4GB DDR3 1333MHz ECC RDIMM; no brackets, cables or additional hardware are included.
