A-Tech 4GB DDR3L 1600 ECC UDIMM

This A-Tech module is a 4GB DDR3L 1600 ECC UDIMM built for server and workstation systems. It runs at 1.35V low voltage with a CL11 latency and uses a 2Rx8 unbuffered design. Major-brand chips are fitted to each 240-pin DIMM.

Suits ECC-capable DDR3L platforms only

This memory fits systems that accept DDR3L 1600 ECC unbuffered DIMMs at 1.35V. It will not work in platforms that require registered or load-reduced modules, nor in boards limited to standard 1.5V DDR3 or non-ECC consumer memory.

2Rx8 ECC unbuffered organisation

The single 4GB stick is organised as 2Rx8 with on-die error correction and no register. Verify that your motherboard or server chassis supports this exact rank, voltage and ECC type before ordering.

Questions about this item

Does my motherboard need a 240-pin DDR3L slot to accept this module?

Yes, this is a 240-pin DDR3L UDIMM, so the board must provide a DDR3L DIMM socket that runs at 1.35 V.

Can I mix this CL11 1600 MHz stick with existing CL9 DDR3L modules?

The system will downclock all modules to the slowest timing, so the CL11 stick will run at CL9 speed if the BIOS allows it.

How do I confirm the ECC function is active after installation?

Enter the BIOS or use an OS tool such as dmidecode and verify that the memory is reported as ECC unbuffered with the correct 4 GB capacity.
