A-Tech 4GB (4x1GB) DDR2 800MHz Desktop RAM

Capacity and Kit Configuration

This A-Tech kit delivers 4 GB of desktop memory using four 1 GB modules. It is built for systems that require DDR2 800 MHz DIMMs and accepts unbuffered non-ECC memory. The 240-pin form factor fits standard desktop motherboards from the DDR2 era. Users upgrading older workstations or legacy PCs will find the quad-channel layout matches many four-slot boards.

Compatibility and Voltage

The memory runs at the standard DDR2 voltage of 1.8 V and carries a tested CAS latency of 6. It suits owners of compatible Acer, ASUS, Dell, HP, Lenovo and similar desktop models that support PC2-6400 speeds. Systems needing ECC, registered modules or a different voltage should choose another product. Always confirm the motherboard specification before purchase.

Deciding Specification

The single specification that determines fit is the DDR2 800 MHz (PC2-6400) speed grade combined with 1.8 V unbuffered non-ECC operation. If the motherboard requires DDR2 800 at this voltage and timing the kit will work; if it needs a different speed, voltage or ECC type it will not.
