A-Tech 4GB DDR3 1600 ECC UDIMM

This 4GB DDR3 module runs at 1600MHz with CL11 latency and standard 1.5V operation. It uses a 240-pin UDIMM form factor and includes ECC error correction for data integrity. The dual-rank 2Rx8 design uses major-brand chips and is tested for server and workstation reliability.

Suited for servers needing ECC UDIMM memory

This module fits systems that accept unbuffered ECC DDR3 DIMMs at 1600MHz. It is not for platforms requiring registered or load-reduced DIMMs. Buyers needing higher capacities per slot or registered memory support should look at different module types.

4GB capacity for light workloads

The single 4GB module handles basic server tasks, virtualisation hosts with modest memory needs, and legacy workstation upgrades. It runs out quickly with large databases, heavy virtualisation, or memory-intensive analytics that demand more than a few gigabytes per channel.

Perguntas sobre este artigo

My motherboard takes DDR3 1600 ECC UDIMM — will this 240-pin module seat correctly?

Yes, the module uses the standard 240-pin DDR3 DIMM form factor and runs at 1.5 V, so it fits any board that accepts DDR3 1600 ECC UDIMM.

Can I mix this CL11 2Rx8 stick with my existing CL9 1Rx8 DDR3 1600 ECC UDIMM?

Mixing ranks and latencies is possible but the system will run all modules at the slowest timing and may limit maximum capacity; check your board manual for supported rank populations.

How can I confirm the module is operating at DDR3 1600 with ECC active after install?

Enter the BIOS or use a tool such as CPU-Z to verify the memory frequency shows 800 MHz (DDR3 1600) and that ECC status reads enabled.
