Server DDR3 ECC RDIMM 4GB

This A-Tech module is a 4GB DDR3 1333MHz PC3-10600 ECC Registered DIMM built for server and workstation systems. It operates at the standard 1.5V DDR3 voltage with CL9 latency and a 1Rx4 rank configuration using major brand chips. The 240-pin form factor fits compatible DDR3 RDIMM slots in supported platforms.

Suits IBM-Lenovo part replacements

It serves as a direct replacement for IBM-Lenovo part numbers 03X3811 and 0A89411, making it suitable for administrators maintaining those specific systems. Builders needing unbuffered UDIMMs, higher capacities, different speeds, or other DDR generations should look at other modules.

Registered ECC with 1Rx4 organisation

The Registered ECC design with 1Rx4 organisation is the specification that determines whether this module works in a given server. Systems that require unbuffered memory or a different rank structure will not accept this DIMM, so verifying the platform's supported memory specification is essential before purchase.

Questions about this item

How do I install the 240-pin DDR3 DIMM and which step do people often miss?

Align the notch on the module with the slot key, press down firmly until both retaining clips click shut, then verify the system recognises the full 4 GB capacity in BIOS.

What maintenance or replacement will this 1.50 V registered ECC module need later?

No routine maintenance is required; the module either continues operating or is replaced if a memory test reports correctable errors that exceed the platform threshold.

What limit appears first when this CL9 1333 MHz kit runs under sustained load?

The DDR3 1333 MT/s data rate and CL9 latency set the maximum sustained bandwidth; the registered buffer adds one cycle but does not create an earlier thermal or power ceiling.
