If it's a CoreDuo (not Core2Duo) you will only get 2Gb of RAM ever. If you install more the machine will either:
1) Refuse to boot (this is most common)
or
2) Only give you access to 2Gb
People have tried this. It did not work. The north/south bridge chipset is limited to 2Gb.

RobbieDuncan is right. Though the guide might prove useful.

It will actually still work once you take the extra RAM out, so if its free it could be worth a shot, alternatively you could get the RAM from Crucial for £20 or so, its crazy cheap at the moment.
hi sorry but im a bit confused now as i was told it wouldnt work and now it will and i would have to take out a 1gb to replace with a 2gb anyway to give 3gb

No. The assumption was that you currently had 1x1Gb and you wanted to add 1x2Gb for 3Gb total. In this case it would make sense to remove the 1x1Gb and replace it with 1x2Gb. If you already have 2x1Gb there is no reason to replace 1 of those with 1x2Gb as this will not work.

...£20? I'm seeing £52 for a 2GB stick on crucial, please point me in the direction of the £20 ones!!
sorry for confusion in my mac i have 2x1gb and wanted to know if i replaced one of the 1gb for a 2gb giving me 3gb would that have worked

That question cannot be answered until you tell us whether your machine is a CoreDuo or a Core2Duo. See post #2 or the guide that was linked.
ok its a CoreDuo, like i said all i was doing was wondering why they had a limit of ram you could install and what would happen if you went over that even by a gb 1x1 plus 1x2 or if it had just a single 2gb could a 1gb be added just the same really
That is because that:
if you are a child only know the number 1~100. But your parents want you to remember all the building number of your 200 neighbors. That will make you crazy.
I've read where some have tried and cannot boot. 1 x 1 is all you're going to get. Better to have matche pairs too.
thanks all looks like im stuck then, im no computer wizz and just for interest sake why isnt
it possible to have external RAM like a HD
