  • 8V unbuffered DIMMs install without configuration
  • Guaranteed compatibility with listed Gateway desktops
  • Two 2GB modules fill both memory slots

System Specific DDR2 Upgrade Kit

This 4 GB kit contains two 2 GB DDR2 DIMMs rated for 667 MHz operation at CL5 timings. The modules run at 1.8 V and use the standard 240-pin unbuffered layout. They are built to match the memory slots of the listed Gateway desktops.

For Gateway Dx4640 and Dx4710 Owners

Buyers restoring or maxing out a Gateway Dx4640-Ubc01A, Dx4710-07 or Dx4710-Eb901A can install this pair directly. The kit will not suit systems that require ECC, registered modules, a different pin count or a voltage other than 1.8 V.

DDR2 667 PC2-5300 Speed Grade

The decisive specification is the DDR2 667 (PC2-5300) rating with CL5 latency. If the target motherboard calls for this exact speed and timing, the kit will function; if it requires a different DDR2 speed grade, these modules will not be compatible.

Questions about this item

How much power does the 1.8V DDR2 667MHz kit draw when the system runs all day?

Each module operates at 1.8V; DDR2 at this voltage typically consumes a few watts per stick under load, so the pair adds only a small amount to total system power.

What must the motherboard provide for these 240-pin DIMMs to work?

The board needs two or four DDR2 240-pin DIMM slots that support PC2-5300 667MHz unbuffered non-ECC memory at 1.8V.

Will the CL5 5-5-5 timing cause issues if I keep the original Gateway memory in the other slots?

The kit runs at CL5 5-5-5; the system will operate all populated slots at the slowest installed module's speed and latency.
