Server memory for IBM-Lenovo systems

This A-Tech module is a 4GB DDR3L 1333MHz ECC registered DIMM built as a direct replacement for IBM-Lenovo part numbers 46C0575 and 43X5313. It targets administrators upgrading compatible server or workstation platforms that require registered error-correcting memory at 1.35V low voltage.

Installation fits standard DDR3 DIMM slots

The module uses a 240-pin DIMM form factor and installs like any registered DDR3 DIMM; ensure the platform supports DDR3L 1.35V operation and registered ECC memory before fitting. Systems that require unbuffered non-ECC modules or a different voltage will not accept this part.

Sustained workloads benefit from ECC registration

Registered buffering and ECC correction maintain data integrity during continuous server duties such as virtualisation hosting or database processing. The CL9 latency and 1333MHz speed deliver steady throughput for supported platforms, though workloads demanding higher bandwidth or capacity per module will need denser or faster memory.

Questions about this item

How can I verify the 4GB DDR3L 1333 ECC RDIMM is working after installation?

Enter the system BIOS or UEFI and confirm the module appears as 4GB at 1333 MHz with ECC registered status.

What comes in the box with this 240-pin 1Rx4 server module and what must be sourced separately?

The package contains the single 4GB DDR3L RDIMM; no cables, brackets or additional parts are included.

Which version should I choose between the IBM-Lenovo 46C0575 and 43X5313 part numbers?

Both part numbers reference the same 4GB DDR3L 1333 ECC registered specification; select the one that matches your system's service documentation.
