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 and Corsair.
On the testbed side of things there's not heaps that needs to be said as you can see our testbed above which gives us a good run down on what exactly is going on. Since there's not a lot that needs to be said in that department, let's get into the overclocking side of things.
Looking below, you can see our final overclock which comes in at 4874MHz or 4.87GHz as represented in our graphs here today. This was achieved by pushing our BCLK up to 125MHz and our multiplier to 39x.
This is a really nice overclock and sits only a little lower than the Rampage IV Extreme which we saw come in at just over 5GHz. While we did manage to get into Windows at 5GHz via a 40x Multiplier and 125 BCLK, we actually got MediaEspresso up and running and I thought we were stable at this speed, but after about 4 minutes we ended with a BSOD.
Dropping the multiplier down just one notch, though, dropped our clock by only 125MHz as you can see, and it was the difference between the system being rock solid and unstable.
Before we get into the performance side of things, though, we'll just quickly cover the boards that are in our graphs today. We've got the higher end Rampage IV Extreme which we absolutely loved. We also have the MSI X79A-GD65, while we've got some Z68 representation via the Maximus IV Extreme-Z and the FX-8150 is here today via the ASRock Fatal1ty 990FX Professional.
Let's get started!
