What this module is

A 4GB DDR3L ECC unbuffered DIMM rated at 1600MHz with CL11 latency. It runs at 1.35V low voltage and uses a single-rank 1Rx8 Samsung chipset. Designed for servers and workstations that require error-correcting memory in a standard 240-pin DDR3 slot.

Installation and common issues

The module inserts into a regular DDR3 DIMM socket and needs no special tools. Ensure the notch aligns with the key on the slot before pressing firmly until the retention clips click. Common problems include mixing voltages or using registered DIMMs in boards that only accept unbuffered modules.

Check before ordering

Verify that your system supports DDR3L at 1.35V and accepts unbuffered ECC UDIMMs. Confirm the motherboard or server manual lists 1Rx8 single-rank modules as compatible. Check the maximum memory per slot and total capacity allowed for your specific platform.

Perguntas sobre este artigo

How can I verify the 4GB DDR3L 1600 ECC UDIMM is running at 1.35V and CL11 after installation?

Enter the system BIOS or use a tool like CPU-Z to confirm the module reports 1600 MHz speed, 1.35V voltage, CL11 latency, and ECC unbuffered status.

What is included with the A-Tech 4GB DDR3L 1600 module and what else is needed?

The box contains one 4GB 240-pin DDR3L UDIMM. No cables or extra parts are required; ensure your server or workstation has a free DDR3 DIMM slot.

Should I choose this 4GB 1Rx8 DDR3L 1600 ECC UDIMM or a different capacity?

Select this 4GB 1Rx8 module if your system needs a single low-voltage ECC unbuffered DIMM at 1600 MHz; add multiple identical units to reach the total memory your board supports.
