I've just picked up a 4770k and a gigabyte ud4h with 8gb corsair vengeance ram but I'm having problems with applying an OC.
I've reused my Dark Rock Pro 2 cooler and temps seem fine, but the machine BSODs really easily. Being a bit of a noob, I applied one of the auto OC profiles which was 1.35v at 4.3ghz. This seemed too high voltage-wise and certainly ran hot.
So, I went into the bios and started dropping the voltage to find a stable OC, and I can't find one ! So after a bit of googling I found this guide,
http://www.overclock.net/t/1401976/the-gigabyte-z87-haswell-overclocking-oc-guide
I spent most of the afternoon changing settings I'm not familiar with per the guide. Left HT and turbo on, but increased CPU ring and LLC - no luck. It's also hard to tell if the bios is holding the settings. The bios has little buttons next each slider but when I save and exit, CPUz doesn't show if they've worked.
In any case all of the settings BSOD within a few minutes of Prime95.
I reset the board to defaults with all settings at auto and the chip idles at 1.01v and boosts to 1.269 at 3.9ghz. This seems high ? Have I got a dud chip ?
My only success was 4.4ghz at 1.354v. Too high ? Temps were topping at 82c with that voltage.
Any help much appreciated.
