Memory upgrade for macbook pro mid 2009

Hi, I want to upgrade my memory in my MACBOOK PRO mid 2009. It currently has 2 x 1GB . Will my macbook pro support corsair-8gb-ddr3-1066mhzC7 DDR3 SODIMM for Apple iMac, MacBook and MacBook Pro 4GB (2x4GB)?? not sure about the last part (4GB). thanks!

PS. I upgaded to mountain lion and it really slowed down my laptop (not much memory space left). Hope this upgrade will speed it up again.

PSS. this is the link to the Corsair I want to buy;

Your computer needs:

Maximum Memory	8.0 GB
Memory Slots	2 - 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM

The RAM specs you have posted will not work in your machine.

Correction Newer RAM Modules run on 1.35v not 1.2v. Sorry about that. Also most RAM now is dual Voltage so they can work in both.

Answer to my question above:

I upgraded my 17" and moved my 4gb Ram from my 17" to my wife's 13".

It worked and all is good.
