Overclocking Help

So I decided to finally try to overclock my CPU myself instead of using the motherboard software. I adjusted the multiplier to 42 on my 3570K before it started to crash at 43. Then I found the Vcore setting on my ASRock Z77M board and tried increasing that by one spot.

The problem is that whenever I adjust the Vcore even that little bit, my PC crashes. So for now I'm at a stable 4.2, but I know it can go further. Any idea why it's doing this? What am I doing wrong?

I have the exact same CPU and similar mobo (I have the ATX version), what cooling do you have?

@GTR12: the CM Hyper 212

@quikdash6:

Leave the vcore at auto, put it to 43, boot into windows and see what cpuid or whatever program you use has the vcore at, go back into uefi, set the vcore to that, but reduce it by 0.05 increments until it wont boot, then go to 44 and do everything again, that's the easiest way of explaining.

TBH I wouldn't go above 4.2 with EVO (unless you're fine with the degrees)

I wouldn't recommend setting the vCore to auto.

Some mobos just set it ridiculously high for the clock you set.

Overclocking is something complex, but easy to do once you're informed. It's a trial and error process to determine the voltage.

I highly recommend you to read this guide:

How exactly did you "adjust" the Vcore? Because normally you'll see lower Vcore than what you set in bios manually, higher the load lower the Vcore. If you have the offset option you can try that and add +0,125V or whatever it offers. You can also try and turn on CPU LLC, it will counter the V drop that occurs on load. Needless to say you need to be very carefull with that. Oh and don't overclock from Windows, go to bios and set it up properly.

That's probably true for older mobos, and even still I've never had a problem leaving it on auto for 10-15 mins just to get a starting point.

No, a lot of mobos still do it.

I remember setting mine at auto @ 4.2GHz and it set it to 1.320v

@EducatingU_PCMR:

You do realise the guide says 1.50v max?

I'm just saying it wont kill the chip using auto for 1.320v for 15 mins or so, then go back and get a baseline at least, instead of just guessing randomly.

@GTR12:

1.5v max probably for water.

Truth, but I'd take for reference people with the same CPU and start from there, since 1.320 is just too high for 4.2GHz.

Or just watch your stock max voltage, take that value and add +25mV each time, so if your 3570K stock is 1.116v + 25mV = 1.141v
