Hello I have searched and searched the internet for a guide on how to overclock my cpu and I just cant get any of them to work for me. Let me first start by admitting I am a noob with this... I have no idea at all how to do this. I was wondering however if there are any nice people on this forum who would take time to help me overclock my CPU? or atleast show me a guide on how to do it. I cant have just a similar guide I need a guide with the same names/options as my motherboard has. As looking at other motherboard BIOS and then trying to find it on my BIOS = a bad head followed by giving up in the face of defeat.

System specs

CPU- i5-4670k
Motherboard-Gigabyte Z87-HD3
GPU- NVIDIA Geforce 770 4gb
MEMORY- DDR3 8gb

There you go, uses a gigabyte board.

Make sure your BIOS is up to date, flash it using Qflash if its not.

Thank you for the reply. If this is as easy as it gets then I am afraid I am doomed. Reading through this guide a lot of it goes straight over my head. Maybe I should just find some sort of shop that is able to do this for me as I dont understand most of what is said in this guide and/or what I am actually supposed to be doing since some of it doesnt give just a number to put it or an option to change.
 
Update your boards BIOS, you must know how to do that?

Then I can maybe show you some things.

Such as setting the Turbo boost ratios to a higher value than they are and thus when the CPU is under load it reaches higher speeds.

My BIOS is updated mate. I am on F7 version, F8 doesnt work on my 64bit system.

If you go into the BIOS and press F12 to get to the classic mode, go look in the frequency section.

Then you are looking for the part that shows the four Turbo ratios, set all four to 40X and save+exit.

If it then boots into winodws without crashing, download CPU-Z which will show you realtime core speed and go run a test like SuperPI 32M or Cinebench.

See if the core speed goes to 4Ghz.

You have got a big heatsink fitted?

Like so? I have a hyper evo 212.

lol sorry about the image size I had to use my phone to take a picture to make sure I was doing the right thing.

Ok so this is the result. Can I just ask you, what exactly did we just do? did we just overclock my CPU to 4GHZ?
 
Yes, 4Ghz when its under load.

If you leave it to idle it will now drop down to 800Mhz or something and the Vcore will also drop.

Best of both worlds.

P>S 1280x pixels wide is the max for pictures, or use spoiler tags like I placed your previous image into.
 
so if I was to change them from 40 to 44 that would be 4.40GHZ? or is that not something I should be doing.
 
Yes it will but then I would imagine you need to set loadline calibration to turbo/extreme and add the necessary offset to the Vcore to feed it the right voltage it demands for that speed.

Or just try it and see if it works at stock voltage.
 
The reason I am trying to OC is because I play Arma 3 and that game is very CPU heavy. So does this mean when I play Arma 3 my CPU will now run at 4GHZ?. I am not sure about going to 4.4GHZ because knowing my luck I will break something haha.
 
Yes, 4Ghz,

Before if you looked at the turbo ratios it started of at 38 with a single core and went down to 36 with all four cores being used.

You are now 4ghz with all four.

P.S Arma is a load of unoptimised crap.
 
Well thank you very much sir :) I Am going to try the 44 and see if it works. I guess the way to tell if it does or not is either my pc wont start up or I will get a blue screen... Something along those line. And if I do I will just change it back to 40. Anything I should be checking for when testing it at 44?.
 
What speed is your RAM suppose to be? what does the memory tab of CPU-Z say?

Try 42x first.

save as you go using the BIOS profiles, so if you have to clear the CMOS, you can just reload that profile and start easily again.
 
I am not sure? It's corsair vengeance ram but I don't remember the actual name of it... Should it be higher or lower then that?.
