I run a 4770k on a Maximus VI Forumla w/ 8 gig ddr3 2133, and a 4gig gtx760. Iv been trying to push just even past 4.0ghz but when I load up bios it shows the proper voltages and speeds. Windows however shows stock or lower then stock speeds in Realbench and CPU-Z. Also my mem frequency does not seem to run at the 2133, What am I missing? And what can I do to get the most out of my setup. I have played with pc's since first gen core2duo extreme days. Any help is appreciated.
