16GB DDR4 2133 Desktop Module

This A-Tech module provides 16GB of DDR4 memory at 2133MHz for desktop computers. It uses the standard 288-pin DIMM form factor and operates at 1.2V. The unbuffered, non-ECC design fits mainstream consumer motherboards.

Suits AMD and Intel desktop upgrades.

Builders replacing Samsung M378A2K43BB1-CPB or M378A2K43CB1-CPB modules will find a direct match. Systems requiring ECC error correction or registered buffering must choose a different module type. Laptop or small-form-factor boards using SO-DIMMs cannot accept this DIMM.

Speed and density decide compatibility

The module runs at DDR4 2133 (PC4-17000) with a 2Rx8 organisation. Verify that your motherboard supports this frequency and density before purchase. A mismatch in speed rank or voltage will prevent the system from booting.
