4GB DDR4 2400MHz Desktop Module

This A-Tech module provides four gigabytes of DDR4 memory at 2400MHz. It uses the standard 1.20V operating voltage and an unbuffered, non-ECC design. The 288-pin DIMM form factor fits typical desktop motherboard slots. It is built as a direct replacement for specific Hynix part numbers.

Suits owners of compatible desktops needing

Builders who want to add a modest amount of capacity to a supported platform will find this module appropriate. It works with both AMD and Intel systems that accept DDR4 2400MHz UDIMMs. Buyers who need more than four gigabytes of total memory should look at higher-capacity kits. Systems requiring ECC or registered memory cannot use this stick.

Fits a standard 288-pin DDR4 slot on a desktop board

The module draws 1.20V, matching the DDR4 baseline, so no extra voltage headroom is required. Its single-rank 1Rx16 organisation leaves other slots free for future expansion. No special cooling or BIOS tuning is mentioned, so it installs like any ordinary UDIMM. Verify your motherboard's supported speeds and maximum capacity before purchasing.
