I own a white MacBook from 2009, it has 2GB. How much of a performance improvment would bumping to 4GB get me for the money? I am thinking of buying these from Crucial http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=964C2F4DA5CA7304

Thanks.

You will notice significant bump in performance by upgrading to 4GB. You are going to be doubling the amount of RAM that you have so it will be able to handle a lot more. You aren't going to see things load faster such as programs or things like that, but once they are up and running, you'll notice a lot less of the beach ball popping up when you are doing things. If you want to really see a serious boost, upgrading the RAM and Hard Drive to a faster drive are going to make significant changes to everything the computer does, but upgrading the RAM is going to make a big difference.

I have a mid-2012 Macbook Pro 13" Non-retina, and it came with 4GB. I'm a mobile DJ and I am going to be getting a new software controller very soon and that needs 4GB to run the software alone. So I bought an 8GB RAM from Crucial Memory. If you go to their website, download their scanner and they'll pull up a list of available RAM and hard drives for your model. I even found a 16GB upgrade and apple doesn't even offer it. And its totally worth the money.

First we need to know which one of the 9 different models of MacBook you have. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info (and then System Report if you’re running 10.7 Lion). When System Profiler comes up check the Model Identifier and post it back here.

The model 5,2 (Early 2009, 2.0GHz Model Only) can use 6gb of 200 pin 667mhz PC2-5300 RAM

The model 5,2 (Mid 2009, 2.13GHz Model Only) can use 6gb of 200 pin 800mhz PC2-6400 RAM

The model 6,1 (Late 2009, White Unibody) can use 8gb of 204 pin 1066mhz PC3-8500 RAM

In 2009 Apple made three models, each one using a different type of RAM.

Is the MacBook Pro 16gb RAM and Intel Iris Pro better or worse than 8gb RAM and GeForce GTX 765m for gaming
