4GB DDR2 667MHz Quad-Channel Kit

This A-Tech kit supplies four 1GB unbuffered DDR2 DIMMs running at 667MHz with CL5 timing at 1.8V. The modules use major-brand chips on 240-pin PC2-5300 sticks and are tested for desktop compatibility. Non-ECC operation suits standard consumer motherboards that accept DDR2 memory.

Upgrading legacy DDR2 desktops

The kit fits older AMD and Intel platforms that support four-module populations at this speed and voltage. Systems limited to two slots, registered memory, ECC requirements, or higher DDR2 speeds will not benefit from this package. Verify the motherboard manual for maximum capacity per slot and total population rules before buying.

1.8V DDR2 voltage

Every module operates at the standard 1.8V DDR2 level; boards that demand lower or higher voltage will not run these sticks reliably. Matching this single electrical specification to the platform is the decisive factor for a successful upgrade.

Questions about this item

Will this kit work in a motherboard that only has two DDR2 slots?

The kit contains four 1 GB modules. You would need four available 240-pin DDR2 slots to use the full 4 GB capacity.

Is the memory compatible with systems that require 1.8 V DDR2 modules?

Yes, each module runs at the standard 1.8 V for DDR2 667 MHz operation.

What do the CL5 and PC2-5300 ratings mean for real-world use?

CL5 indicates a CAS latency of five cycles at 667 MHz, and PC2-5300 denotes the peak transfer rate of 5300 MB/s for this DDR2 speed grade.
