We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: Intel, ASUS, MSI, Western Digital, MemoRight and Corsair.

On the hardware side of things we really don't see anything different in our testbed and everything is really covered in the above image. Because of that we'll move straight into the boards that we'll be using in our graphs here today outside of the ASUS P8Z77-I Deluxe which will be running at both stock and overclocked speeds.

Alongside the ASUS offering we've also got the ASRock Mini-ITX Z77E-ITX motherboard we recently looked at along with the larger Z77 Extreme6 offering from ASRock. To round out our collection of boards here today we've also got the ASRock X79 Extreme4 and ASUS Maximus IV Extreme-Z.

Before we get into the performance we want to quickly go over the overclocking side of things to see just what kind of performance we're able to get out of the board. Starting off with the multiplier we changed that to 46x to help push our CPU to an even 4.6GHz. We got into Windows with no problem and we started to do a few things and everything was okay.

With that looking good we headed back into the BIOS and moved to a 47x multiplier, but we didn't experience the same luck. Because of that we headed back into the BIOS and moved to 46x and messed around with the BCLK a little. Not having much luck we decided to settle on 46x.

Someway through our testing we started to get some stability issues so we had to head back into the BIOS and we moved down to a 45x multiplier, which as you can see above resulted in an even 4.5GHz, which is represented in our graphs here today.

Let's get started!
