I just got a Strontium (a company that overprices memory and spamvertizes or has exceptionally not bright customers) DDR3 4GB Ram to put it in my MacBook pro and it’s exceptionally fast. It boots within 15 seconds, and any app launches almost instantly. It's easily the best upgrade I have ever made hardware wise in 3 years...have used so many products from other memory manufacturers but so far Strontium has been the best in terms of performance. In terms of ram versions, DDR3 URL of overpriced lame company removed is slightly faster and draws less power which increases the life of your battery.
Go away, spammer. Why would someone pay double the going rate on memory, when you can buy 8GB for half the price of your link?
A one post wonder spamvertising overpriced RAM. 😡
