Those are a good set, you won't go wrong with them. If you're adventurous, you could grab 3 or 4 sets of these: http://www.amazon.com/Samsung-Electronics-Extreme-MV-3V...
(I don't know if they ship to New Zealand) and then bin them yourself, and get them dialed in and running faster than the G.Skill set will. The set I linked are what many memory "manufacturers" bin and sell after attaching heat spreaders.
True true, that's actually what I was going to get, but the sales rep
Said its for the i7 3770 ivy bridge, lol I gave him a blank look and said its RAM, faster ram etc
Then he said its specifically tested for that and may not work too well on your system..
So I wasn't so sure, that one should be fine yes?
2400mhz trident X
True true, some good info, do you know why they say that certain RAMs can only be used with certain processors? I don't understand this, I thought RAM would work anywhere, specially the fastest RAM
Should work with no issues on the rampage iv.
The top speed ram from Gskill is only qualifies for ivy bridge :S
