installing ram into MacBook, early version 2008

I went to install my 2mb chip and was expecting to see another 2 mb chip in there, giving me 4mb. but whats in there is 2 512K chips, so i currently have 1 mb. What do I do, can I take one out and replace with the 2mb for a total of 2.5 or can I take out both and just have one at 2mb. I thought I remember hearing something about you have to have the same in both slots. Help? Thanks - I have 2.1 ghz intel core 2 duo, currently with 1gb 667 mhz ddr2 sdram. The 2gb chip is ddr2, Kingston pc2-5300, the tech sold me at Best Buy .

Apple ships their machines with the memory slots populated. That means a MacBook with 1 GB of memory will have 2 x 512 MB chips installed.

You'll need to purchase another 2 GB chip from Kingston (Best Buy) in order to bring your MacBook up to 4 GB. Make sure the 2 GB chip you purchase is exactly the same as the one you already have.

Regards.

Do I have to get it from them best buy? Can I just get the same thing from whereever? And so I need to populate both slots? thanks

also is 4mb the most I can put in there? thanks

Why would you need more than 4 GB, in fact what do you plan on doing that needs more that 2 GB? Why not try the 2 GB chip and see how much you use on day to day stuff. i use MenuMeters so i can see the usage at all times so that way you would know how quickly you allocate your 2 GB

You can get the RAM from wherever you want as long as it meets the required specs for your machine.

I will be using alot of stuff at once and I plan also to have to use VMWare so I can use Publisher, which I dont want to use, but have to as Im getting some things that are in that format and no way around it.

4GB is the max. Plenty to run a VM, plenty.
