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 Hynix chips in a 1Rx8 single-rank layout and carries Supermicro certification. The unbuffered ECC design targets servers and workstations that require error correction without registered signalling.

Check DDR3L 1.35V support and 240-pin UDIMM slots

Verify that your motherboard accepts DDR3L memory at 1.35V rather than standard 1.5V DDR3. Confirm the board provides unbuffered ECC UDIMM slots with 240-pin keying and supports PC3L-12800 speed. Single-rank 1Rx8 organisation must be compatible with your system's memory controller for proper operation.

Steady ECC correction during continuous workloads

Error-correcting code operates on every cycle, detecting and correcting single-bit errors while flagging multi-bit faults without pausing the pipeline. Low-voltage DDR3L reduces power draw and heat during sustained throughput, helping maintain signal integrity. Supermicro certification confirms the module passes extended validation for 24/7 server duty.

Questions about this item

Does the 4GB DDR3L 1600 CL11 ECC UDIMM come as a single stick or a kit, and is anything else needed to install it?

The module is sold as a single 4GB stick (1Rx8, 240-pin); no extra parts are required beyond a compatible DDR3L UDIMM slot.

Should I choose the 1.35V DDR3L 1600 CL11 version or a different voltage or speed for my Supermicro system?

Select this exact 1.35V DDR3L 1600 CL11 module when your Supermicro platform specifies PC3L-12800 ECC unbuffered memory; other voltages or speeds will not match the certified part number.

What does the 1600MHz rating mean once the MEM-DR340L-HL05-EU16 is installed in a server?

The memory runs at 1600MHz with CL11 timing at 1.35V, delivering the certified DDR3L 1600 ECC unbuffered performance validated for Supermicro systems.
