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.

Before we get into the overclocking side of things let's cover the boards that will be in our graphs today. Apart from the BIOSTAR TZ77XE4 at both stock speeds and overclocked we've also got Z77 offerings from ASRock in the Z77 Extreme6 and ASUS in the Maximus V GENE.

Along with that we've also got the older Z68 based ASUS Maximus IV Extreme-Z and the ASRock X79 Extreme4 to round out our collection of boards here today. With that said let's get into the overclocking side of things to see just what we can get out of our Intel 3770k CPU and the BIOSTAR TZ77XE4.

Heading into the BIOS to do some overclocking it took a little bit of time to get our head around it since this is a new BIOS design for us. Fortunately everything is pretty clear and it didn't take us too long to get into it.

One of the features that I liked the most, though, is that as we move up in voltage levels the color changes as we get to higher and higher levels. As we increase our voltages we move from white to orange and then orange to red. This is a really handy feature for people who want to do a bit of overclocking, they can move to levels that they feel safe and make sure they don't cause any damage.

After setting the voltages and everything you can see above we ended up in Windows at 4702MHz or 4.7GHz as listed in our graphs here today. This was done by leaving the BCLK at 100 and moving our multiplier to 47x.

We ended up getting into Windows at 4.8GHz, but due to heat, we could see the CPU bouncing between 4.4GHz and 4.8GHz, as it overheated. We dropped the voltage a little and moved out multiplier back 1x and you can see where we ended up.

Let's get started!
