Well, for the most part it's possible to OC a lot of components, with the right mobo. You have a good mobo, so the answer is yes!
There are one or two ways to increase performance. You can either tighten timings to make the DIMMS run slightly faster at stock speed (2400mhz). By tightening the timings you can get more performance.
The other way is to go for more speed. Which means loosening timings (most of the time) and increasing the voltage supplied to the DIMMS to increase the actual speed at which they operate. Example being my own generic ram. It's rated at 2400mhz, but I have it running at 2733mhz.
In both cases, you 'may' have to increase memory voltage and/or the SOC voltage a notch or two so that the DIMMS are stable. If they are not stable they can crash games, prevent the PC from starting up properly amongst other things.
You can test the settings you try with memtest86+ (this will be put on a bootable USB stick and run outside of the windows environment).
