Interesting point Spinflight - what you refer to is dual channel memory, which is implemented on pretty much all mobos these days. I have never understood it, but now need to.
I have two "matched" 512MB DDRAM sticks, but could use another gigabyte of memory, to perk performance up a bit. I have only three slots and of course, two are already in use. So - the big Q... With matched memory on a dual channel mobo, can I add an odd size (though same spec) stick, or must I stay with just another 512mb?
Over to you chaps!
