late 2009 macbook RAM upgrade

hi everyone, i'm looking to upgrade my RAM on my late 2009 white macbook. it's not really handling osx lion that well so it's time for an upgrade. i was looking at this kingston RAM...2, 2gb sticks. is this any good? any other suggestions?

What about spending 20 USD more and getting 8GB of RAM, like with two of these?

it says it can only handle 4gb total though

hmmm ok, what's the difference between the kingston you recommend and this one: http://www.amazon.com/Kingston-Modules-1066MHz-KTA-MB1066K2-4GR/dp/B001RUI3Q0/ref=pd_cp_e_4

sorry, i'm ignorant with regard to this stuff.

They will work too, and the difference is, that I linked you to a 4GB module, and you linked to two 2GB modules. If you have the money, and don't mind having any extra RAM, I would go for it. But 4GB RAM might more than suffice your needs.

the link i gave is for 2, 4, or 8gb...the one i sent is more expensive, just wondering why. yours is "value ram".
