Macbook Pro 15inch Late 2008 Ram upgrade

I have a 15inch Macbook Pro"M98" late 2008 cpu 2.8. I currently have 4GB installed, I was doing some reading and have seen some people mention that 8GB of ram is possible. But I wasn't sure if mine was able to and if anyone in the forums could verify it for me. Also do the ram chips have to be matching or could I even install 1 4gb chip for 6gb of ram? Or do both have to be matchinig 2x4gb chips?

Macbook Pro, Mac OS X (10.6.4)

ahh okay so 6GB would be my cap, what would be the best way to achieve 6GB? Are 2x3GB chips being offered, or would just 1 4GB chip with my previous 2GB chip be the way to get 6GB cap?

You can only use one 4 GB module and one 2 GB module. There are no 3 GB modules.

Most likely you will need to purchase both unless Apple shipped you a computer with one 2 GB module. More likely there are two 1 GB modules installed.

I see, well I have 2x2GB chips already installed when I bought my computer from apple. So all I need to do is purchase a 4GB from there store and I'm set? Does it have to be an apple 4GB?

Yes, that should work. No, you don't have to purchase from Apple. A couple good sources are Data Mem and OWC. Just be sure to buy RAM with the specifications provided in the computer's user manual.
