Server ECC RDIMM for DDR3L platforms

This 4GB A-Tech module is a registered ECC DIMM built for servers and workstations that require DDR3L 1333 memory. It operates at 1.35V with a CL9 latency and uses a 2Rx8 organisation on a 240-pin form factor.

Suits systems needing registered low-voltage ECC

It fits machines that specifically call for DDR3L registered ECC RDIMMs at 1333 MT/s. Builders whose platforms require unbuffered ECC, non-ECC UDIMMs, higher capacities per module, or a different DDR generation should look at something else.

Registered ECC with 2Rx8 organisation

The single specification that decides fit is the registered ECC RDIMM design with 2Rx8 ranking; only motherboards wired for registered ECC at DDR3L 1333 will accept this module.

Questions about this item

Will the 1.35V DDR3L voltage limit power headroom under sustained server loads?

The module runs at 1.35V DDR3L low voltage, reducing power draw and thermal output during continuous operation compared to standard 1.5V DDR3.

How much heat and noise does the registered ECC design add during all-day use?

Registered ECC RDIMM modules have no moving parts; they add negligible heat and zero acoustic noise regardless of workload duration.

Which motherboard slot and chipset must I already have for this 240-pin RDIMM to function?

You need a DDR3 DIMM slot (240-pin) on a server or workstation board that supports registered ECC memory and 1.35V DDR3L operation.
