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.
As always you can see our main testbed information in the above image, so there's no real need to go into too much detail; instead we'll just get into the overclocking side of things to see what the mATX X79 Extreme4-M is capable of.
The one thing we noticed on the X79 Extreme4 was while overclocking performance was strong, it preferred to run at a lower BCLK and instead opt for the higher multiplier. Going into the Extreme4-M BIOS, we found ourselves doing the same thing.
In the end we ended up in Windows running with a 43x Multiplier and 100 BCLK which brought our CPU clock in at 4.3GHz. We could actually get into Windows higher than this, as high as 4.6GHz actually, but we found under CPU intensive tasks the CPU clock would drop down for some reason.
Considering the mATX stature of the board, though, this isn't too bad an overclock at all and should bring with it a nice little performance increase over the stock numbers. Considering the size of the board, you could probably build yourself an awesome mATX system around it. We need to see what performance is like first, though.
Let's get started!
