I've NEVER OC'd before. I have an i5 3570k and coolermaster v6 air cooler, I wanted to get my CPU up to 4.5 GHz. Any tips before I try? I have 700w 80 plus and asrocke extreme4 motherboard.
I'd recommend to start with your voltage at 1.320 to start. My 3570k can run at 4.5Ghz with 1.300 Vcore voltage. So this will give you a good starting point.
When you test your rig for stability always go with Intel Burn In Test. I personally, run IBT AND I play a game at the same time to see if I can get my PC to crash. If it crashes then go up on your voltage. This is the only way I know of to make sure that you are completely stable for sure. Cause I can run IBT and Prime95 for hours on it without any crashes but as soon as I play a game it'll crash. That's why I test with both.
Also, make sure that you can do everything you want to do on your PC to make sure your stable. Open Word, Internet, play games, anything you would normally do.
You also need to check the event viewer to see if you have any WHEA errors. If you do your not stable. You will probably have some errors just make sure they're not WHEA.
And just my advice, turn intel speed step off and all other power saving features. I'd recommend that.
I think your ASRock MB has some kind of automatic or "one button" overclock functionality - you could start out with that just to see what it comes up with. It should give you an option to OC at the default voltage.
My 3570k is stable at 4.1Ghz without touching the voltage (on an ASUS P8Z77-V PRO) - just turn up the multiplier.
