Hi Alastair, Maximum Memory: 6.0 GB (Actual) 4.0 GB (Apple) Memory Slots: 2 - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMM
It can take 6GB... but there are NO 3GB RAM modules. As general guidelines for optimum performance, it's usually best to make sure your Mac has the same amount of RAM in each slot. i.e 2GB + 2GB or 4GB + 4GB You obviously have a 2GB + 1GB installed in your MacBook now, giving you a total of 3GB RAM I have been told that MacBooks with 6 GB maximums will take one 4GB plus one 2GB, but two 4GB modules (giving you total 8GB) crash the machine as soon as the OS tries to access more than 4096 MB of memory. BUT, I would wait for Daniel Kerr (MacWizardry) to confirm or deny this as he knows much more about memory modules than I... Daniel is the "Memory Man" - "RAM Man" ;-)) Cheers, Ronni 17" MacBook Pro 2.3GHz Quad-Core i7 “Thunderbolt" 2.3GHz / 8GB / 750GB @ 7200rpm HD OS X 10.8.2 Mountain Lion Windows 7 Ultimate (under sufferance) On 24/11/2012, at 11:46 AM, alastair taylor <alas.i...@iinet.net.au> wrote: > Hi all > > My macbook (white 2008 model 4,1 2.4Ghz, 3Gb ram) is very slow.
