In addition to what Slay Mate said, I checked your motherboard's memory compatibility chart.
Your OCZ RAM is listed there, but being that it's 1600 Mhz standard, you may need to lower your RAM down and overclock your CPU, because the i7 860's standard memory frequencies are DDR3 1066/1333
In order to run that RAM at 1600, you'll have to be overclocking the NBFreq? Or wtfever they call it these days...
And keep your RAM voltage as low as possible, I wouldn't run i7 RAM any higher than 1.66V or as Slay Mate said, more than .5v higher than the VTT.
So what I think you'll end up having is your CPU and NBFreq(Or wtfever it is these days) overclocked, having your memory downed a little bit, and having your DRAM voltage turned down and your VTT raised.
You should be able to get some stability?
