I'd suggest going to one of the major RAM suppliers like Crucial. You can plug your computer info into their "memory advisor tool" and it will tell you exactly what your computer is capable of handling. Generally speaking it's usually better to not mix and match but to get matched pairs of RAM (2x2GB, 2x4GB, etc.) Once you know what your computer can handle and the exact memory specifications, you can shop around for the lowest prices. Just as an example, a few days ago Newegg had 8GB DDR3 RAM (2x4GB) for under $50.

If you install more than is supported one of two things will happen. One, the computer will not boot at all. Two, it will boot but the extra memory will be unseen and unavailable for anything.

In any case according to the specs for that model,

it can take up to 8 GB of DDR3 at 1066 MHz.

A 1333 will be backwards compatible to 1066. For example:

I notice from your posted info that you have 32 bit Windows 7 .
The maximum RAM that Windows 7 32 bit can use is about 3.25 GB.
To use more you must install Windows 7 x64 (64 bit).

A 64 bit version of Windows would be required to make all 4GB accessible, but the 32 bit versions allow 4GB of RAM to be present. (Home Starter limits it to 2GB.) Some people can't bear the thought of not having all of their RAM available to Windows, but aside from that it works OK.

On a laptop, I recommend using only identical DIMMs. The laptops I've played with lack the manual BIOS settings that would make it easier for RAM of different makes to work together nicely.
