from what i understand, it's best to have RAM installed in matched pairs (2x256, 2x512, etc.), but is it really bad to have unmatched pairs? i ask, because i am probably going to be buying a refurbished rev. a macbook that comes with the stock 2x256 RAM, and i want to upgrade it. my dilemna is that i can't really afford to upgrade it to the full 2GB all at once, and i don't want to do an upgrade to 2x512 because then i'll be wasting even more RAM once i upgrade to 2x1024. so what i'd like to do, if it wouldn't be extremely detrimental, is buy one single 1024 stick at a time, giving me 1.25GB for a while, until i eventually upgrade the other stick and have 2GB. so, would it be bad to do this?
Got a tip for us?

Basically it makes the graphics card slower, if you were using final cut express or something it might be a problem
oh so you're saying for like WORKING with graphics, right? don't think i'll be doing much of that, other than some very light photo editing in iphoto or messing with imovie.
Mismatched RAM will run dual channel the macbook's chipset. Read this thread https://forums.macrumors.com/threads/245348/
or at least it will on the MBPs. I really don't like the macbook names

I'll preface this with the note that I am still a fairly new Mac user.
My MBP had the stock 512MB of RAM with 1 DIMM. I added a second DIMM that was 256, and the computer appeared to run slightly slower and things appeared to hang more.
Upgraded to the C2D MBP, and had the stock 1DIMMx1GB. Added the same second stick of 256, and it appeared to slow slightly, but still worked better overall than the single 1DIMM with 1gig of memory.
These are simply my observations.
