great thanks - between crucial, kingston and this ram from transint, any recommendations? or are they all equal?
I can't say - I only have 1 GB of Apple RAM ( I think it's also by Crucial ) and
6GB of TransIntl. TransIntl RAM has a lifetime warranty and the first 2GB I bought from them had some CRC errors, I RMA'ed it and they sent me a replacement. Just make sure to keep all the customs invoicing because
SARS will double tax you if you ever RMA anything and the company sends you a replacement. They don't care what the company writes. They just want to make a quick buck.
However the other 4GB has worked perfectly as does the replacement RAM.
Computer runs silent. My Toughbook is louder than my Mac Pro

.
I've maxed this RAM out many times with Compressor, Final Cut Pro, Photoshop, VM Fusion and have also tested it to 100% utilisation with a Memory testing application.
TransIntl ship to SA and don't ask for any faxed credit card statements or passports, so using your CC there is straightforward.
Oh and my other favourite Apple online store is Toolfarm. ToolFarm.com sells very little Apple hardware but you can buy all the Adobe Products and Apple Products there,
at cheaper than Core prices with Flat Rate shipping by FedEx (USD $55 for a 10kg box

).
