I am new to the overclocking world. I have an i7 920 on a Gigabyte UD4P board with a Cooler Master V8 heatsync. I am running 12 gigs of DDR3 @ 1600 Mhz primarily on Vista 64. I have a Diamond Radeon 4890 and am going to get another one on Monday to run in Crossfire. My PSU is the SilverStone Stryder Series Low-Noise 1000 Watt PSU. I have never been able to keep my system stable at more than 3.2 Ghz for any amount of time. Can anyone help me set up a stable clock speed of 3.6 Ghz or better?
