Compatible 16GB DDR4 Upgrade

This A-Tech module provides 16GB of DDR4 memory running at 2133MHz with a PC4-17000 rating. It uses the standard 288-pin DIMM form factor and operates at 1.20V. The kit is a direct replacement for Micron MTA16ATF2G64AZ-2G1 and MTA16ATF2G64AZ-2G1B1 modules.

For Non-ECC Desktop Systems

This unbuffered, non-ECC UDIMM suits standard desktop computers using AMD or Intel platforms that accept DDR4 2133MHz memory. Builders requiring Error Correcting Code, registered buffers, or speeds beyond 2133MHz should select a different module.

288-Pin DDR4 DIMM Interface

The decisive specification is the 288-pin DDR4 DIMM interface combined with 2133MHz speed and non-ECC unbuffered architecture. Verify your motherboard supports this exact combination before purchase.
