Server DDR3 ECC SO-DIMM kit

This 16GB kit contains two 8GB DDR3 1600 SO-DIMM modules with ECC and unbuffered operation. It is built for servers and workstations that require error-correcting memory in a 204-pin form factor. The 2Rx8 rank configuration supports stable performance in compatible multi-slot systems.

Upgrade from non-ECC or lower capacity

Replacing standard unbuffered SO-DIMM without ECC adds single-bit error correction for data integrity in always-on workloads. Moving up from 8GB or 4GB modules doubles usable memory per slot, which helps when virtualisation or database caches exceed current limits. The jump is worth it when uptime and data accuracy outweigh the cost of non-ECC alternatives.

16GB total capacity headroom

Two 8GB modules give 16GB total, enough for light virtualisation hosts, file servers or development workstations running moderate workloads. Memory-intensive databases, large container fleets or heavy compute nodes will exhaust this capacity quickly. Systems limited to two SO-DIMM slots cannot expand further without replacing the kit entirely.

Questions about this item

Does this 204-pin SO-DIMM fit my server's DDR3 memory slots?

The kit uses 204-pin DDR3 SO-DIMM modules, which is the standard physical interface for DDR3 laptop and compact server memory slots.

What is the correct way to install these 2Rx8 ECC modules so the server recognises them?

Insert each 8 GB module firmly into the slot until the side clips click; the common mistake is stopping before the clips engage, leaving the contact pads partially unseated.

Will the ECC function on these unbuffered modules degrade over time and require replacement?

ECC capability is a permanent feature of the memory chips and does not wear out; replacement is only needed if a module fails or capacity must be increased.
