  • Smooth multitasking from 4GB total capacity
  • Low latency performance using CL7 timing
  • Reliable operation from 12 years DRAM expertise
  • Guaranteed compatibility with system-specific design

4GB DDR2 1066MHz Kit

This kit provides 4GB of DDR2 memory in a matched pair of 2GB modules running at 1066MHz with CL7 latency. It suits older desktop systems that still rely on DDR2 architecture for everyday tasks. The unbuffered UDIMM format fits standard consumer motherboards without registered memory support.

Unbuffered UDIMM Build

Modules use a standard unbuffered UDIMM design that installs directly into desktop DIMM slots without extra configuration. The CL7 timing at 1066MHz delivers responsive access for the platform. Gold-edge contacts resist oxidation and maintain reliable electrical connection over years of service.

Upgrade from Lower Capacity

Replaces smaller or slower DDR2 kits to raise total system memory to 4GB and tighten latency to CL7. The jump is worthwhile when the board supports 1066MHz operation and the workload benefits from the extra headroom. Systems limited to lower speeds will still run the modules at their maximum supported rate.

Questions about this item

What speed and bandwidth does the DDR2 PC2-8500 rating deliver?

The kit runs at 1066 MT/s with a PC2-8500 bandwidth rating, capping transfer rates at that specification.

What physical module format must the motherboard accept?

Each 2 GB module is a 240-pin unbuffered UDIMM, so the board needs standard desktop DDR2 DIMM slots.

Which installation step is most often missed with a matched pair?

Insert both modules into the same-channel slots — usually the identically coloured pair — to enable dual-channel operation.
