Overclocking an i5 4670k with MSI Z87-G45 Gaming?

Ian Dayon · Jun 10, 2014

Hey guys, its my first time overclocking and i have already watched a few videos, tips, tricks, and guides on how to overclock. Just to be sure, I know that even though you have the same cpu and mobo, but you have different sets of coolers, cases, video cards, fans. I might not get the exact temperature as them when following their guides.

Since my Corsair H80i is arriving a few hours from now i wanted to know the step by step process on how to over clock this cpu of mine.

Right now, I have a heat sink with 2 fans on them (Enermax ETS-T40).
And yes, i have tried overclocking it at 3.4GHz, thats what the CPUID stated, so it must be default. I havent touched anything in BIOS yet.
I ran a stress test with these settings and reached around 76*C.

I heard people overclocking them to 4.9GHz.

But no, i dont want that.
I am planning to overclock mine up to 4.4GHz only, so basically plus 1GHz on my default setting. (with my Corsair H80i ofcourse).

Edit: I forgot to mention that i am replacing the Corsair H80i fans to 2 Noctua NF-F12's running in push-pull. I am going to put my Corsair fans (from the H80i) to the front and the top vents for more RPM, dont worry my previous fans were crap. I dont mind the sound.

Just follow the guides for the best settings in your bios, increase the multiplier not the BCLK. Do a small increment, save then stress test. If its good then repeat. Its long winded but the best and safest way to do it. All CPU's have different OC potential (even the same type) but you wont have any issues with 4.4GHz oc. keep an eye on thermals and dont ramp up the CPU voltage, OC as much as you can on the lowest voltage until unstable then make a small increase to voltage if needed (check specs of your CPU for max voltage). Also more voltage increases heat a lot. Dont attempt anything until your new cooler is installed, also test the CPU after installation to make sure its working correctly. Just take your time and remember if you accidentally mess a setting in bios you can always revert it back to default so dont be afraid to play around (its the best way to learn).

Here is a handy thread which helped me get to 4.6 GHz: http://www.tomshardware.com/forum/id-1722630/intel-god-quick-dirty-guide-4ghz-haswell.html
I put in some BIOS screenshots. I believe that they are on Pg. 3.

Just don't go over 1.300 v.! Make your voltage changes in steps of 0.010 v.

where can i see my voltage of my cpu? :O

Y0GI :

where can i change my voltage? on the BIOS?

Ian Dayon :

Yes, you can change it in the BIOS.

An easier method, which does not require rebooting the computer, is to use the MSI-Intel Extreme Tuning Utility (IXTU) which should've come on the MSI furnished CD with your mobo.

I find that it is much easier to make changes "on the fly" with IXTU.
