Wanting To Upgrade From 512mb To 1gb RAM

I currently have 2 RAM slots in my PC and each of them are holding a 256 RAM card. I'm hoping to buy two 512mb RAM cards to replace the 256's but is there anything I should know before I buy them?

Also, if I can't afford two 512mb cards would it be possible to have a 256mb RAM card + a 512mb RAM card so that I've got 768mb RAM? Just wondering because I heard somewhere that you can't combine two different sizes of RAM.

Thanks

It varies by manufacturer and board model.Simplest, whether you buy from them or not, is to use the memory advisor at www.crucial.com. If you have a name brand machine, or if you know the motherboard make and model, it can tell you exactly what you can use in your particular machine, and whether memory must be installed in same-sized pairsor can it be mixed.

 

Here's what the scan results said but it doesn't say whether I can have 2 different sizes of RAM installed:

To be honest, I would be very surprised if you couldn't have 2 different sized memory modules in your motherboard, as pretty much every modern motherboard has been designed to accept the different sizes.
