DDR2 667MHz desktop memory upgrade

This A-Tech module is a 1GB DDR2 667MHz PC2-5300 UDIMM built for desktop computers. It runs at the standard 1.8V and uses a 240-pin unbuffered non-ECC design. The stick is tested at 667 MHz and carries CL5 latency for basic system responsiveness.

Suits older DDR2 systems only

The module fits motherboards that accept DDR2 DIMMs at 667MHz with 1.8V operation. Systems requiring ECC, registered memory or a different DDR generation will not work with this part. Check your board manual for supported speed and voltage before buying.

240-pin DDR2 DIMM form factor

The single specification that decides fit is the 240-pin DDR2 DIMM interface. Only motherboards with DDR2 slots keyed for 1.8V unbuffered modules can accept this upgrade.

Questions about this item

Does my motherboard need a 240-pin DDR2 slot to install this module?

Yes, this UDIMM uses the standard 240-pin DIMM form factor and requires a desktop DDR2 socket.

Will the 1.80V specification match the voltage of other DDR2 sticks I keep in the system?

The module runs at the standard DDR2 voltage of 1.80V, so it aligns with other DDR2 memory operating at that level.

How can I confirm the stick is running at the tested 667 frequency after installation?

Check the memory speed reported in your BIOS or a system-information utility; it should show 667 MHz for this PC2-5300 module.
