Hey everybody, noob overclocker here, however I'm no stranger to computers. I built my rig a year ago and am deciding it's time to give it some more juice.
i5-4690k w/Z97x Gaming 7 mobo using XTU:
I understand that to raise the core/cache clock past a certain point, you need to up the core voltage. My CPU is stable at 4.2ghz with default/stock voltage settings, so I figured it's alright to leave it there. Temps are excellent under full CPU load with all cores enabled at around 49-52°C. I've tried pushing it to 4.3ghz with the core voltage at +1.2v and it crashes. I have not messed around with any BIOS settings as I've read many mixed posts on what people think is best to do in there. I'd like to think I have a decent rig as I invested quite a bit into it, and I know this CPU can push past 4.2 so I don't know where I'm going wrong. Any help appreciated!
