What This Module Is

This A-Tech server memory module provides 4GB of DDR3L capacity at 1333MHz with ECC error correction and registered signalling. It operates at 1.35V low voltage using a 2Rx8 organisation on a 240-pin DIMM form factor. The module is built with major brand chips and tested for dependable operation in compatible IBM-Lenovo systems.

Who This Suits

This module suits administrators upgrading or repairing IBM-Lenovo servers that specifically require DDR3L 1333 ECC registered DIMMs matching part numbers 46C0564, 49Y1389 or 49Y3777. Builders needing higher densities, different voltages, unbuffered DIMMs or newer memory generations should look elsewhere because this product addresses only the listed specification.

Build Integration

The 240-pin DIMM installs directly into DDR3L registered memory slots on supported server motherboards. Its 1.35V operation reduces power draw compared to standard DDR3 modules while the registered buffer lightens electrical load on the memory controller. ECC functionality helps maintain data integrity for workloads that demand error detection and correction.

Questions sur cet article

Does my server need a DDR3L 240-pin registered DIMM slot to accept this 4GB module?

Yes, this is a DDR3L 1333 240-pin ECC RDIMM; the motherboard must support registered DDR3L DIMMs at 1.35V.

Can I install this 1.35V DDR3L RDIMM alongside existing 1.5V DDR3 registered DIMMs in the same system?

Mixing 1.35V DDR3L and 1.5V DDR3 registered modules is not recommended; the platform typically defaults all slots to the higher voltage.

How can I confirm the module is running at 1333MHz with ECC active after installation?

Check the BIOS memory information or OS tools such as dmidecode; they should report 1333MT/s, registered ECC, and 1.35V operation.
