16 GB DDR4 ECC SO-DIMM Kit

This 16 GB kit contains two 8 GB DDR4 2133 SO-DIMM modules with ECC and an unbuffered design. It targets servers or workstations that require error correction in a 260-pin form factor. The 2Rx8 rank organisation suits platforms that accept unbuffered ECC memory. Buyers needing registered DIMMs or higher speeds should look elsewhere.

Compatibility Checklist

Verify that your system accepts 260-pin DDR4 SO-DIMMs running at 2133 MT/s with ECC enabled. Confirm the motherboard or server manual lists support for unbuffered ECC modules and the 2Rx8 rank configuration. Ensure the BIOS can initialise ECC without requiring registered memory. Systems limited to non-ECC or registered-only slots will not work with this kit.

Build and Daily Use

The modules use a standard green PCB with 260 gold-edge contacts that seat firmly in SO-DIMM slots. ECC circuitry adds single-bit error correction for data integrity during continuous operation. Unbuffered design keeps latency low for supported platforms. The matched pair simplifies dual-channel population. No heatsinks are included, so airflow in dense chassis remains the builder's responsibility.

Questions about this item

Does the kit include both 8 GB SO-DIMMs or must the second module be purchased separately?

The kit contains two 8 GB modules for a total of 16 GB, so nothing else is required for that capacity.

Should I choose the 2133 MT/s speed or a faster DDR4 option for my server?

Select 2133 MT/s if your platform specifies DDR4 2133 or PC4 17000; faster DDR4 will down-clock to this speed.

What does the PC4 17000 rating mean once the memory is installed?

It indicates a peak transfer rate of 17 000 MB/s at the rated 2133 MT/s data rate.
