Server memory module

This A-Tech 4GB DDR3 module is a registered ECC DIMM designed for server and workstation systems that require error-correcting memory. It operates at 1866MHz with a CAS latency of CL13 and standard 1.5V voltage.

Compatibility fit

The module suits administrators upgrading IBM-Lenovo systems referencing part 00D5020 or any platform accepting DDR3 240-pin registered ECC memory. Builders needing unbuffered desktop DIMMs, SO-DIMM laptop modules, or higher-density configurations should look elsewhere.

Registered ECC requirement

The single specification that decides fit is the registered ECC design; the system memory controller must support registered DIMMs with ECC enabled for this module to function.

Questions about this item

How can I confirm the A-Tech 4GB DDR3 1866MHz ECC RDIMM is working correctly after installation?

The server should POST without memory errors and the BIOS or OS will report 4GB at 1866MHz with ECC active.

What is included with the module and what must be purchased separately?

The box contains one 4GB 240-pin DDR3 ECC RDIMM; no extra parts are required for a compatible slot.

Which version should I choose if my system needs a 1Rx4 registered module at 1.5V?

This single 4GB 1Rx4 DDR3 1866MHz CL13 1.5V ECC RDIMM matches those exact specifications.
