This is an auction for:

4.0GB(2.0GB+2.0GB) PC12800 DDR3 1600MHz SO-DIMM Memory (2 sticks of 2Gb RAM)

You would use this to increase the RAM in your laptop to improve performance. You will need a free slot/s or have smaller size ram sticks in your laptop for this to be of use. It is a really cost effective way of getting a performance improvement

You can always Google you laptop to see what type of RAM you need and see whether this is suitable.

Ram has been increasing in price and it makes the price of these two cheaper than a single new stick!! Also, these are getting harder to get. Great value!!

The photo is generic and the brands will change but the sticks will be the same brand such as Samsung, Hynix, Elpida etc. This is not the right RAM for desktop computers

Grab a bargain, preferably grabs lots of bargains because I have plenty of these. You can always make me an offer. I I probably have in excess of 200 sticks, if you suddenly need a couple of hundred I am your man !!

If you want to see typically what is involved in changing RAM you can try this YouTube Video:
