A-Tech 4GB DDR3 1600 ECC SODIMM

This 4 GB DDR3 module runs at 1600 MHz with CL11 latency and 1.5 V operation. It uses a 204-pin SO-DIMM form factor and provides ECC error correction in an unbuffered design. The single-rank 1Rx8 organisation suits compatible DDR3 platforms.

Microservers, mobile workstations

Builders upgrading a system that accepts DDR3 ECC unbuffered SO-DIMM memory will gain data-integrity protection. Systems limited to non-ECC DDR3 or those requiring registered modules cannot use this part. Buyers needing higher capacity should look elsewhere.

ECC unbuffered DDR3 SO-DIMM with 1Rx8 layout

The combination of ECC unbuffered operation and single-rank x8 organisation determines whether the module works in a given platform. Verify that the motherboard or chassis explicitly supports ECC unbuffered DDR3 SO-DIMM before purchase.

Questions about this item

What comes in the box with the A-Tech 4GB DDR3 1600 ECC SODIMM and do I need anything else?

The box contains one 4GB DDR3 1600 ECC SODIMM module. No extra cables or brackets are required; the module installs directly into a compatible 204-pin SO-DIMM slot.

Should I choose this 4GB single-rank ECC SODIMM or a different capacity for my microserver?

This module provides 4GB in a single 1Rx8 rank at 1.5V. Select it when your system needs ECC unbuffered DDR3 SO-DIMMs and you want a single 4GB stick; add a second identical module if your board supports dual-channel operation.

What does the 1600 MHz speed rating mean once the module is installed in my NAS server?

The module runs at DDR3 1600 (PC3-12800) with CL11 latency at standard 1.5V, delivering the rated throughput when the platform enables ECC unbuffered operation at that frequency.
