i have the same motherboard and an i5 2500k, heres what u do, go into bios by pressing "del" key at boot up and click on OC Genie Mode II, then click on OC settings, disable intel turbo boost and enhanced turbo, next go to "my oc genie" and select option "customize", next go to "my oc genie option" and select " my oc genie CPU ratio" and set it to 40/41/42 whatever maximum oc u can get, save settings and exit.
EDIT: remember to enable extreme memory profile (X.M.P) in auto mode otherwise your ram will run at a default clock of 1333mhz
