Crucial SO-DIMM 4GB Kit DDR2 667MHz CL5

Slow laptop? Make it faster with Crucial!

Due to the lack of RAM, your laptop can be easily outpaced by the latest applications. With this Crucial set of two 2GB memory modules designed for SO-DIMM slots, your old machine can get a second wind. All you need is to make sure your laptop's processor is DDR2 compatible and has two free SO-DIMM slots.

Increases system performance

This 200-pin Crucial memory module runs at 667 MHz frequency. Its power supply is 1.8V and it runs at CL5 timing. On the manufacturer's website you can easily find if it's compatible with your computer. If you can find it, Crucial gives you 100% compatibility guarantee.

Attention: DDR2 is compatible neither with the older DDR, nor with the newer DDR3 slot!

They work OK in aged notebook HP-550 (replace the original one gigabyte module). Noticeable acceleration in all directions, but it's probably not surprising. No, and I hope it will remain so for a long time :-)
