Server DDR3 ECC UDIMM 8GB

This A-Tech module is an 8GB DDR3-1333 ECC UDIMM built for server and workstation systems. It operates at PC3-10600 speed with CL9 latency and standard 1.50V voltage. The unbuffered 2Rx8 design uses major brand chips and fits 240-pin DIMM slots.

Replaces IBM-Lenovo DDR3 modules

It serves as a direct replacement for IBM-Lenovo part numbers including 03T8429, 0A65718, 0A89461, 47J0171, 90Y3164, 90Y3165, and 90Y3167. The upgrade is worthwhile when a compatible system supports DDR3 ECC UDIMM memory and requires additional capacity for heavier workloads. Buyers needing registered DIMMs or a different DDR generation cannot use this module.

8GB capacity for moderate workloads

The single 8GB module handles typical server tasks such as virtualisation, database caching, and multi-user applications with room for multitasking. Headroom decreases when running many virtual machines or large in-memory datasets that exceed the installed capacity. Systems requiring more than 8GB per slot or higher memory bandwidth will need additional modules or a different platform.

Questions about this item

Will the 240-pin DIMM fit in a standard DDR3 UDIMM slot on my server board?

Yes — the module is a 240-pin DDR3 UDIMM, so it installs in any DDR3 UDIMM slot keyed for 1.5 V operation.

What is the correct way to seat the module and what step do people skip?

Align the notch with the slot key, press straight down until both side clips snap shut, then verify the system reports the full 8 GB at 1333 MHz.

How long before the ECC chips or the 1.5 V power circuit might need replacement?

DDR3 ECC UDIMMs have no moving parts and are rated for continuous server duty; they typically last the life of the platform unless physical damage or voltage surges occur.
