Why do my ASRock Z87 Extreme4 pre-fab overclocks crash?

Hello,

I am new to overclocking and have read many guides including this one

However, my motherboard's interface is different and does not have all the fields listed, which is making things very difficult. I tried loading the ASRock's pre-defined 4.4 and 4.2 GHz OCs and they both freeze my computer during a prime95 test. My current clock is using the 4.0 preset and ran a 10 minute prime-95 with a maximum temperature of 60 degrees Celsius on an un-calibrated realtemp.

II am using a Haswell i7-4770K processor and I've read in many places that 4.4 should be easy to obtain on this chip, and I feel that my cooler is more than enough to handle the clock. I don't understand why the pre-defined ones would crash it.

Best solution

Yes, you should not be having any issue OCing. What were the temps during 4.2 and 4.4?
Instead of using the ASRock presets I suggest just going to the BIOS and changing the multiplier to 42 and leave everything else default/auto.

I'll have to get back to you on the temps on the higher frequencies. Will just changing the clock be sufficient for for 4.4 if 4.2 proves stable?

Yes just change the multiplier to 44 and let your board auto adjust to what it needs. Motherboards know best XD.

You may have to increase Vcore to get to 4.4 stable.

A lot of good info in this thread: http://www.tomshardware.com/forum/id-1722630/intel-god-...

I have it at 4.2 now, and during a 10 minute p95 test one core spiked to 63 degrees for a second, but they all stayed within 58-60 otherwise. My idle (browsing the internet) core temps are 32-38 degrees.

Very good temps!

Turns out that my crashes were actually unrelated to my clocks. I've been using the same sound card for about 8 years now and the drivers really did not like the new motherboard. Had to remove it and everything works like a charm now.

The weirdest things sometimes cause issues.
