Yeah you need to chunk the two 512mb I'm afraid. ifixit has a good and easy to follow guide.

You could also buy a 2gb stick, but that would be mighty expensive.

Yeah, getting a 1x2GB stick is just not worth it. Buy 2x1GB sticks off Newegg. The installation is a breeze. Just make sure the RAM is in, give it a bit of force.

don't buy the 1x2GB for macbook
those are only for MacBook PRo
cause for macbook intergrated graphic card to perform well, you need 2 identical size of RAM installed on both Slots.
be it 512 + 512 or 1G +1G (cause of the "dual channel" thingy)

What is up with Matching Memory???

:confused: How is it with the new laptops and desktops, you've got to match the memory. I don't see anyone refering to their 768 Ram or 1.25 ram etc...What would happen if I got a Macbook and put in 1.5 or 1.25? Would it stick it's binary tongue out at me :p and say "No way Jose'!"

Help me understand matching pairs!

Thanks again,

The difference isn't that great, but if they are not a matched pair they won't operate in Dual channel configuration.

Since the Macbook relies on main system memory in place of vram (and IRRC main memory is not dual ported memory like what dedicated GPUs have), you need every ounce of performance you can squeeze out of them.

Haha. It wouldn't stick its binary tounge out at you. Realistically, I don't think you'd notice a big difference. There wouldn't be anything wrong with using 768MB or 1.25GB of RAM. The benefits gained from using dual-channel (matched pairs) seem to be debateable, with some people saying that using 1GB matched would be better than 1.5 unmatched, and others saying the opposite. I haven't seen any documentation that definitively confirms either case.

I'd take the advice of temujin and follow the iFixit guides. They usually have great, easy-to-follow instructions on fixing and upgrading almost any part of almost any Mac.

As far as where to buy RAM, I always recommend Data Memory Systems for all Mac RAM purchases. I've used them for all my RAM upgrades, and have never had a problem. They've got great prices, great service, and offer lifetime guarantees on their RAM with advance replacement. I don't think you can go wrong with them, and you're probably safer doing that than buying cheaper RAM off of other sites.
