Attention before buying, it is essential to check that the model is compatible. Unfortunately, manufacturers usually provide very little information for the novice, while this is technically not rocket science. Software can be used (like Speccy for example), and inspect or strips already installed in the computer (after turning it off and removing the battery of course!)
In loccurrence, I had a strip of 4 GB and a free slot, so it was very easy to add this bar to double the Kingston memory of my PC. Everything works perfectly so far and Windows 7 is actually in much better fate for some heavy tasks or when many software and internet tabs open.
If you really want to boost your computer's responsiveness account should consider a replacement against the traditional SSD hard drive, but it's a bit more complicated if we clone the disk, and more expensive too.
