Hi, I've been inqureing about ram upgrading and head that there could be some issues if adding ram in non-pair chips. i.e. just one 128MB chip instead of 2. is that true? do I have to buy ram in pairs to make any upgrade? Hope I'm being clear about my question.
Regards, Alejandro.

Single chips alone are fine. Chips of different sizes may be fine if their speed is the same ( measured in nanoseconds )
On my first PPC Mac I threw them all in from 4 to 64 MB. 128 MB total. What a mess. Constant crash / freeze.
A single 128 solved the problem. I weeded out the DIMMs tha6 caused problems on a backup machine. The ones that work nice together are still in it.
Just don't put an EDO chip in a 7200 motherboard.
