My System Specs

Default Intel Core I7-3820 Overclocking

Just wanted to share some of my overclocking experiences with anyone who may be trying to overclock their 3820 or who may get one in the future.

I was finally able to get my system stable yesterday with a 4.625GHz overclock. I am using a corsair H80 for cooling. I also have all 8 dimms filled with Corsair 4GB Sticks for a total of 32GB of vengeance ram rated for 1600MHz. I am using an ASUS Rampage IV Extreme X79 motherboard in my system.
The Vcore is set to 1.36 but on load it will bump it up to 1.376. Ran Prim 95 on Each Setting for 12 hours to make sure this overclock was stable.
