I always say if you have an older machine max out the memory with the
best memory for your machine, if you don't know what kind will give you this
better performance find out which kind will give you the best via websites out
there but I don't know of any... I was told this after buying 2-512's for my
A1025 Titanium after taking out 2-256's!!! Different manufacturers I guess is
what he was talking about??? Does anyone out there know what I am talking about
or could help with that info if that person was right??? Once you max it out
you can rule out the memory!!! CoolKat
