If you need more than 4x4gb you need a server

You will not get anything else this good and this cheap for a while, certainly not in 8gb sticks. If you do want to look into 8gb though crucial have some ballistix with the same part number, voltage and timings as the 4gb sticks everyone is drooling over in the crucial thread. You could buy 6 kits of this for the same price as a single kit of 2x8gb crucial though...see what I mean about those prices? You better make damn sure you need more than 16gb before you go for 8gb sticks.
