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.
