8 GB DDR2 SO-DIMM kit for laptop upgrades

This 8 GB kit contains two 4 GB DDR2 SDRAM modules rated at PC2-6400 (DDR2-800). Each stick uses the 200-pin SO-DIMM form factor and is manufactured in the United States. The matched pair is designed to populate both slots in compatible notebooks for full dual-channel bandwidth.

Replaces mismatched or lower-capacity DDR2 sticks

Installing this kit removes the bottleneck of mixed-speed modules or a single 4 GB DIMM that forces single-channel operation. The upgrade is worthwhile when the system chipset and BIOS recognise the full 8 GB and both slots are free for the matched pair.

Sustained load behaviour with DDR2-800 modules

Under continuous workloads the modules operate at their rated 800 MHz bus speed with standard DDR2 voltage and timing. Stability depends on the notebook’s memory controller and thermal solution, as the SO-DIMM format leaves no room for additional heatsinks.

Questions about this item

What slot type and pin count does this 8GB DDR2 kit require?

The modules use a 200-pin SO-DIMM form factor that fits DDR2 SODIMM slots in compatible laptops.

How do I install the two 4GB modules correctly?

Align the notch on each module with the key in the slot, insert firmly until the contacts are fully seated, then press down until the side clips lock automatically.

When might these DDR2-800 modules need replacement?

Replace them if the system fails memory diagnostics, shows repeated crashes, or if you upgrade to a platform that no longer supports DDR2 technology.
