So I got my new G.Skill kit today. I was pleasantly suprised that getting it to run at spec was as easy as 1.9Volts and setting it to spec. 680I's have known problems at running higher spec memory with all the dimms filled up. The heatsinks on these chips are massive compared to my old G.Skill sticks. I'll have to do some tweaking to see how far I can actually push them.
