That's kind of what I was getting at... 2.2 isn't too high. You are almost running the same voltages my DDR500 is running- granted you need the heatsinks plus that OCZ cooler to pull it all off, but you got it working none the less. 2.2 is possible and not all that far fetched with the right cooling, as you have very much proven with your rig.
