SimpyTimpy   10 #1 Posted March 9, 2011 Hey guys,  Quick question, I'm looking to upgrade my MacBook (Late 2008, Aluminium) from 2GB RAM to 4GB.  The new RAM I've got is the right spec (DDR3 PC-8500) but it's 4GB on one module instead of 2 x 2GB.  I'm pretty sure the jump from 4GB-5GB wouldn't be that noticeable if I were to keep one of the old memory modules installed, and I've read (and it makes sense) that having two pieces of memory of different sizes isn't the optimum way.  Wondering if:  (a) It's OK if I were to install the 4GB module on it's own, leaving one memory slot empty (b) If there really is any degradation in performance if it were 1x 1GB and 1x 4GB. © Which approach is best.  Thanks!

Ghozer   112 #2 Posted March 9, 2011 I think they only support 4GB maximum (on 2x2GB) so installing 1x 4GB (with or without a 1GB aswell) may result in..  only 3GB showing.. or no response at all...  but if it works, then leaving a 1GB in, wouldn't affect it really to be honest...
