Server DDR3 ECC RDIMM Upgrade

This 4 GB A-Tech module is a registered ECC DIMM built for server and workstation boards that require DDR3 1600 memory. It replaces IBM-Lenovo part numbers 47J0164 and 90Y3154 and installs in standard 240-pin DDR3 slots.

Capacity and headroom

The single 4 GB stick adds modest capacity for light virtualization, file serving or legacy application workloads. Systems needing larger memory footprints or higher bandwidth will require additional modules or a platform that supports greater densities.

Compatibility assurance

Each unit is tested to match the original IBM-Lenovo specifications for voltage, timing and register behaviour. The matched validation reduces the risk of POST errors or instability when populating qualified server platforms.

Questions about this item

Will this 4GB DDR3 1600MHz ECC RDIMM run alongside my existing 1.50V registered modules in the same server?

Yes, it operates at the standard 1.50V DDR3 voltage and uses the same registered ECC design, so it can mix with other 1.50V registered DIMMs of matching speed and rank.

How can I confirm the 2Rx8 registered ECC module is detected correctly after installation?

Check the system BIOS or UEFI memory information screen; it should show 4GB at 1600MHz with ECC and registered status for the new DIMM.

Does the single 240-pin DIMM include any extra brackets or cables, or is it just the memory stick?

Only the 4GB DDR3 240-pin RDIMM is included; no brackets, cables or additional hardware are supplied.
