A-Tech 4GB DDR3 1600 ECC UDIMM

This 4GB DDR3 1600 module is an ECC unbuffered DIMM built for server and workstation systems that require error-correcting memory. It runs at PC3-12800 speed with CL11 latency at the standard 1.5V. The single-rank 1Rx8 layout uses major-brand chips on a 240-pin PCB. It serves as a direct replacement for several Kingston part numbers.

Suits servers needing ECC unbuffered DDR3

This module fits systems that specifically call for DDR3 ECC UDIMMs at 1600MHz and 1.5V. It is not for platforms that require registered or load-reduced DIMMs, nor for boards that only accept non-ECC memory. Buyers whose hardware demands higher capacities per slot or a different DDR generation should look elsewhere. Verify your system's qualified vendor list before ordering.

The deciding spec is ECC UDIMM at DDR3 1600

The combination of ECC unbuffered operation and DDR3 1600 speed determines whether this part will work. Motherboards wired for registered ECC, non-ECC, or a different DDR generation will not accept it. Check the manual or QVL for PC3-12800 ECC UDIMM support at 1.5V before purchasing.

Questions about this item

Does the 240-pin DDR3 DIMM fit a standard unbuffered ECC UDIMM slot?

Yes, the module uses the standard 240-pin DDR3 DIMM form factor for ECC UDIMM slots in server and workstation boards.

What is the correct orientation when seating the 1Rx8 module?

Align the notch on the module with the key in the slot, press down firmly until both side clips click into place.

Will the 1.5V major-brand chips need active cooling or replacement over time?

The chips run at standard 1.5V DDR3 voltage and are tested for long-term reliability; no active cooling or scheduled replacement is required.
