A-Tech 16GB DDR5 4800MHz Desktop Module

This A-Tech module delivers 16GB of DDR5 memory at 4800MHz with CL40 latency. It operates at the standard 1.10V for DDR5 and uses an unbuffered, non-ECC design. The 288-pin DIMM fits standard desktop slots.

Suits Hynix replacement; not for ECC systems

This module is a compatible replacement for Hynix HMCG78AEBUA and HMCG78MEBUA part numbers. It suits owners of those specific modules needing a direct swap. Systems requiring ECC or registered memory should look at a different part.

16GB capacity decides fit

The single specification that determines compatibility is the 16GB density in a single rank x8 organisation. Verify your board supports this exact capacity per slot before purchase.
