A-Tech
An 8 GB DDR3-1600 ECC registered DIMM with CL11 latency and 1.5 V operation for IBM-Lenovo servers
This A-Tech module delivers 8GB of DDR3 1600MHz registered ECC memory for server and workstation systems. It operates at 1.50V with CL11 latency and a 2Rx8 rank configuration. The 240-pin DIMM is built as a compatible replacement for IBM-Lenovo part numbers 47J0212 and 00D4995.
This module fits systems that require DDR3 ECC registered DIMMs at 1600MHz. It will not work in platforms that need unbuffered memory, non-ECC modules, or a different DDR generation. Builders using consumer desktop boards or laptops should look at something else.
The single specification that decides fit is the registered ECC 2Rx8 organisation at DDR3 1600MHz. Your system must support registered error-correcting modules with this rank layout and speed; otherwise the module will not be recognised or will cause instability.

Align the notch on the module with the slot key, press down firmly until both retention clips click, and verify the system recognises the 8 GB capacity at 1600 MHz.
No scheduled firmware updates or component swaps are required; the module is tested for lifetime reliability at CL11 latency.
The 1.5 V DDR3 standard voltage and CL11 timing define the operating envelope; sustained loads stay within JEDEC limits for registered DIMMs.
