Help overclocking i5-4670k

KDK · 14 May 2015 at 18:50

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.

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?

KDK · 14 May 2015 at 20:36

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.

KDK · 14 May 2015 at 20:39

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.

KDK · 14 May 2015 at 20:44

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?.

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?.

KDK · 14 May 2015 at 20:59

Finished with 587cb this time rather then the last which was 551cb

KDK · 14 May 2015 at 21:04

Ok, Try again with what though? I know I am sorry I am not sure how I am supposed to change the size of the images.

CPU-Z, see what it says after.

You heard of Microsoft paint? it comes free with every copy of windows since dinosaurs roamed the earth.

haha yes sorry thats what I take the picture using too. I will resize from now on. Sorry again.

KDK · 14 May 2015 at 21:16

Ok I done the changes you told me to do and this is how both tabs look now. Is that ok?.

Wot cpu cooler do you have?

I see at 4.2ghz the bios has auto adapted the voltage to 1.318v.That will run the cpu very hot without adequate cooling.

I have a Hyper EVO 212

Memory is now running correctly.

Was it running slower then it should have been? I am not sure how this could happen because I have never changed anything in my BIOS to do with memory.

Also should I run an IntelBurnTest to check my temps now that I have the 42 setting?.

You should learn about Vcore offset now, so instead of the board auto increasing the Vcore for you.

You set the offset to be whatever you want to add to the stock voltage.

So at stock speed if your CPU uses 1.15V but needs 1.3V for 4.2GHZ, you set the offset to +0.15v.

Those are just numbers I picked out of thin air, so dont use them exactly.

So does that just mean if my Vcore is now 0.961 at idle and 1.318 when its underload, I have to change the offset to the difference between those 2 numbers? +0.35v

I found this - http://www.tomshardware.co.uk/forum/id-1722630/intel-god-quick-dirty-guide-4ghz-haswell.html

I was wondering what the options 2,4,5 are called on my BIOS because I dont find anything with the same name or similar to what is said in this guide -
2. Set CPU cache Multiplier also called the Ring bus multiplier to 35
4. Set CPU Cache Voltage also could be called Ring Bus voltage to 1.20v -1.25vv
5. Set Vrin also called "CPU Input Voltage" To 1.9v - 2.1v

KDK · 16 May 2015 at 17:52

3. Set Fixed CPU Vcore to 1.25 -1.30 - I have at 1.26
4. Set CPU Cache Voltage also could be called Ring Bus voltage to 1.20v -1.25vv - 1.25
5. Set Vrin also called "CPU Input Voltage" To 1.9v - 2.1v - 2

Should I be trying to get those voltages down to a minimum without it causing crashes? Should I just keep trying to lower them until I can find the lowest volts that it is stable at? or do I have it all wrong and I should be going up and not down?

Does it still reduce the core speed and the voltage at idle?

The core speed yes but the voltage no. Should it be?.

This is my latest test, highest CPU temps when running cinebench is 75

This is at idle

The voltage yes, ideally.

What you need to do instead of setting a voltage, type in Normal or press PageDN or PageUP till Normal appears, then underneath the offset option should go from being greyed out and unusable to being usable.

The offset is what you want to add to the stock voltage to reach say 1.269

So if stock is 1.1V and you need 1.269V to be stable, set offset to +0.169

And it will add that value when underload.

And if I go up to say 46 I would just do it again but change the offset by however many it needs?.

I think that's what you mean? Sorry about the image size but I had to use my phone to take it.
