i7-4770K Unable to overclock

post #1 of 11
Thread Starter 
I just put together a new build with asrock z87 extreme 4 and an i7-4770K, I changed the multiplier to "all cores" and set it to 40. I then changed the CPU voltage to 1.2. After booting into windows 7, CPU-Z reports 3500mhz under load with a multiplier range shown as 8-40...

Any ideas?

Turn off your c-state/power saving options in the bios, can't recall which ones exactly right now too sleepy. Check this thread, you can pull some accurate information, note its for sandy and ivy on z77 but for your issue you can see what c-state settings and power options to have enabled/disabled.

but like rv8000 said.. try reading you thru the guide and find some more hints about
what could be braking you.. GL

im getting it to OC leaving everything auto - only changing the multiplier (not optimized at all). Its got to be some setting hanging it up.

Will try again tomorrow...

everything on auto is rather bad..

take some time and read thru some guides here on OCN to understand some
basics and configure your hardware more efficient.

Depends on the board. I can't speak for ASRock, but ASUS is putting together an OC guide for their new Z87 boards, and they actually recommend auto settings for the majority of the power settings - the boards are much better on auto settings than they used to be.

CPU-Z reports Vcore @ 1.2v when I change the multiplier to 40 (for 4.0ghz OC). This is after I loaded defaults (incase I accidently changed something I shouldn't have by accident). Everything is AUTO/default except for the multiplier.

The funny thing is when I fix the voltage to 1.2, it boots, but only after I manually restart it 3 times (it hangs on Code 51). Once I restart 3 time it boots and enters windows; and CPU-Z is reporting the correct clock speed now. Once I shutdown the computer from within windows, it will need to be booted up again.

Again, i'll need to trial and error more stuff based on the posted OC guide. Was getting tired last night... had to call it a day .

EDIT: MacClipper, do you mind posting your setting with the extreme 4 board? just the ones you changed related to CPU/OC. Thanks!

You can make it easy on yourself when you are starting out new on Haswell, get into the BIOS and then choose the factory set profiles. Set all the rest eg. RAM/GPU etc... to its factory specs initially to eliminate any unnecessary extra factors.

Once you are more familiar with the BIOS, you can then slowly fine tune everything else from there.


Z87 Extreme4 - Overclocking Profiles
- simply mouse click select then fine tune to your heart's desire, it's almost too easy


Eg. CPU@Turbo 4.4 (up from 3.8) selected (and then DIY tweaked for 4.5GHz), GPU@1.5GHz (up from 1.2)

Hmm...I used ASRocks preset OC settings to get it up to 4.2Ghz and 1.152 Vcore. I've got the Z87E-ITX which I think is pretty similar to your board.

Have you tried anything higher? Couldn't get mine to stay stable at higher clocks...
