Hey guys, my 12 inch pb right now has the stock amount of ram in it, and it slows a bit when Im doing a lot at once. I was thinking of bumping the ram up to a gig. Will that help? Whats the cheapest place to get ram and what kind do I need? I'm not sure if there are two 256 sticks in my pb right now or what, so whats the best combination? Thanks in advance guys.
