I've had that setup for years and my system is still running well. At max load my temps average 70-75C, but that's only possible because I'm running on water. You are definitely going to need a better cooling setup if you want to push past 4GHz because you're going to have to increase the voltage to get there. That's why I posted the link above for you to read on how to safely overclock your Gulftown CPU. My other settings are listed below.
ASUS Rampage III Formula
24GB Corsair Dominator DDR3-2000 (CAS 9-10-9-27 T2)
CPU VCore 1.45
DRAM Voltage 1.65
So I used your settings and when I ran Prime95 I was getting 100' Celsius....any suggestions to get temp down? I use the Pacific r360 watercooler by Thermaltake and yes it is seated right with artic silver...I have a Rampage 2 extreme with 48gb gskill mem all 6 slots filled up...I am waiting for Asus to send me back rampage 3 extreme black edition...help would be greatly appreciated
