Upgrade Kit for Select Laptops

This kit supplies 8 GB of DDR2 memory arranged as four 2 GB modules built to the PC2-4200 standard at 533 MHz with CL4 latency. It targets owners of compatible laptops, all-in-one PCs or NAS units that use 200-pin SO-DIMM slots and want a straightforward capacity increase.

Suitable for Systems with Four DDR2 SO-DIMM Slots

Buyers whose machines have fewer than four available slots, require ECC or registered memory, or need a different voltage or speed should look at other options. The kit is also not intended for desktop DIMM form factors or for platforms that do not support unbuffered DDR2 SO-DIMMs.

200-Pin DDR2 SO-DIMM Form Factor Decides

Only devices equipped with 200-pin DDR2 SO-DIMM sockets running at 1.8 V can use these modules. Verify the motherboard or system manual for this exact slot type before purchase.
