I try to OC my 2600K on that motherboard but whatever I do every settings is accepted (RAM OC, Over-Voltage and all the rest) but my CPU remains at 3.4Ghz whatever happens.
me and my friend tried anything we knew and were able to find on internet for around 3hours and we seriously don't know what to do anymore.
