Yeah, I don't know about that processor but those settings sound fine. If you have CPU Z, run it and check the voltage being drawn. I've found some of those voltages are a rough starting point for some overclocking.
I've been able to get 1.261volts for 4.5 ghz. Most of the results will vary somewhat. Cooling is what allows me to get the voltages down, watercooled.
I haven't put my waterblock on the new kingpin yet, back just won't co operate today, but I managed to hook up the 670s to this board and so far got some amazing results, as high as 7076 on the memory and 1176 on the core with the high temp of 26 C under load. 1174/7076 in sli no less. Best pr for ASIC I've had, though my kpe ti's were 77 and 79 %. Absolutely awesome cards btw !!!
