A-Tech 4GB DDR2 667MHz desktop memory kit

This A-Tech kit supplies four gigabytes of DDR2 memory across two 2GB unbuffered DIMMs. It is built for desktop computers that accept 240-pin modules running at 667 MHz. The dual-channel configuration helps improve throughput on compatible platforms.

Compatibility check for DDR2 667MHz systems

The modules suit owners of older AMD or Intel desktops that specify DDR2 667 (PC2-5300) unbuffered non-ECC memory at 1.8V. Anyone whose board requires registered, ECC, or a different DDR generation should select a different product.

Deciding specification: DDR2 667MHz 240-pin DIMM

The single specification that determines fit is the DDR2 667MHz 240-pin DIMM form factor with 1.8V operation. If your motherboard calls for this exact combination the kit will install; if it calls for any other generation or pin count it will not.
