A-Tech 2GB DDR2 667MHz UDIMM

This module provides 2GB of DDR2 memory rated at 667MHz (PC2-5300) with standard 1.8V operation. It uses an unbuffered, non-ECC 240-pin DIMM form factor designed for desktop computers. The kit contains a single stick suitable for AMD and Intel platforms that accept this specification.

Check motherboard DDR2 slot

Before ordering, confirm the motherboard has an available 240-pin DDR2 DIMM slot and officially supports 667MHz modules at 1.8V. Verify the board’s maximum memory capacity per slot and total system limit using the manual or vendor documentation. Ensure the BIOS is updated if required for full compatibility with this density.

Suits legacy DDR2 desktops needing a single 2GB

This upgrade suits older desktop PCs that require DDR2 667MHz memory and have a free 240-pin slot for a 2GB module. Systems needing ECC, registered, or lower-voltage DDR2 should look elsewhere. Machines already at their memory ceiling or using a different DDR generation will not accept this module.

Questions about this item

Will this module fit a desktop that requires DDR2 667MHz PC2-5300 UDIMM memory?

Yes, the module is a 240-pin DDR2 DIMM rated at 667MHz with PC2-5300 speed and 1.8V operation, matching those specifications.

Is this memory compatible with systems that only accept ECC or registered modules?

No, this is a non-ECC unbuffered UDIMM, so it will not work in motherboards that require ECC or registered memory.

Can I add this 2GB stick alongside existing DDR2 modules running at a different speed?

The module will run at the speed of the slowest installed memory, so mixing speeds is possible but the system will operate at the lower frequency.
