Black Diamond Memory BD8GX22133MQO22 16GB (2 x 8GB) DDR4 2133 ECC Unbuffered SO-DIMM server RAM

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.
