How much RAM can i use on my (Late 2010 White) Macbook? #Hackintosh

I have the White poly-carbonate 13 inch Macbook. The final one of its kind that was released in late 2010.

i would like to purchase more RAM to improve my computers performance. But i dont want to waste money and end up with RAM i cant use. Can anybody tell me how much i should buy for maximum performance ?



-Thanks
