Server ECC DDR3 module

This 4 GB Kingston DDR3 1600 module carries ECC and runs unbuffered at CL11. It fits 240-pin DIMM slots and operates at the standard 1.50 V JEDEC voltage. The part is aimed at budget-conscious server builds and white-box assemblies that need error correction.

Straightforward DIMM installation

Align the notch on the 240-pin edge connector with the slot key and press until the latches click. No extra cables, drivers or firmware steps are required. The most common issue is mixing this unbuffered ECC stick with registered modules or non-ECC memory, which prevents the system from posting.

Suits entry servers needing ECC

Builders populating a DDR3 platform that specifically calls for unbuffered ECC will find the capacity and speed match the spec. Buyers whose motherboard requires registered ECC or a higher density per slot should look elsewhere. Systems limited to non-ECC memory cannot use the error-correction feature this module provides.

Questions about this item

How do I confirm the module is running at DDR3 1600 with CL11 after installation?

Check the BIOS or a system tool such as CPU-Z; the memory tab should show 1600 MT/s, PC3 12800 bandwidth and CAS latency 11.

Does the package contain only the 240-pin DIMM or are any cables or brackets included?

The box holds the single 4 GB unbuffered ECC DIMM; no cables, brackets or additional hardware are supplied.

I see only one capacity listed — how do I decide if 4 GB is enough or if I should look for a larger module?

Match the capacity to your server's maximum per slot and total limit; 4 GB suits light workloads or filling empty slots, while heavier duties need higher-capacity sticks.
