A-Tech 4GB DDR3L 1600 ECC UDIMM

This 4GB DDR3L module runs at 1600MHz with CL11 latency and 1.35V low-voltage operation. It uses a 240-pin UDIMM form factor with ECC error correction and unbuffered signalling. The 2Rx8 rank organisation uses major-brand chips for server and workstation workloads.

Server and workstation upgrades needing ECC UDIMM

Suited for systems that require DDR3L ECC unbuffered memory at 1.35V. Not for platforms that only accept registered or load-reduced DIMMs, nor for boards limited to standard 1.5V DDR3 without low-voltage support. Buyers needing higher density than 4GB per module should look elsewhere.

240-pin DDR3L 1600 ECC UDIMM 1.35V

The 240-pin DDR3L interface at 1.35V determines whether this module fits and functions. Verify that your motherboard specifies DDR3L 1600 ECC UDIMM support before purchasing. An incorrect voltage or missing ECC capability will prevent the module from working.

Questions about this item

Will the 2Rx8 ECC chips on this DDR3L module need replacing under normal server workloads?

The module uses major-brand chips tested to A-Tech quality standards and carries a lifetime warranty, so the 2Rx8 ECC components are not a scheduled replacement item.

What limit appears first when this 1.35 V DDR3L 1600 UDIMM runs sustained loads?

The CL11 latency at 1600 MHz sets the throughput ceiling; sustained bandwidth will plateau at the PC3L-12800 rating before voltage or thermal limits are reached.

How much heat and power does a single 4 GB 240-pin DDR3L stick draw in 24/7 operation?

At 1.35 V the module draws less power and generates less heat than standard 1.5 V DDR3, keeping thermal output low during continuous server duty.
