Overclocking for Beginners

[tg31270]

I would like to start overclocking, but every single tutorial I find seems to be very straitforward (change voltage and multiplier) but I would like to understand how it works and not do a tweak without knowing what is happening.

I have a 3570K,

Thank you for replying

Well to be easy and short.

When you change the voltage, you change how much electricity the processor will receiver.

The multiplier is how much you multiply the clock speed of the unit. (the ghz thingy ;)

What motherboard do you have? Some motherboards have over clocking programs you can use to automatically over clock your CPU.

Linus also has a i7 Overclocking tutorial which i imagine would be very similar to overclocking your i5 -

Some programs you may want to look into are:

Intel Extreme Tuning Utility - http://www.intel.com.au/content/www/us/en/motherboards/desktop-motherboards/desktop-boards-software-extreme-tuning-utility.html

Core Temp - http://www.alcpu.com/CoreTemp/

Thanks,

I have a GD55 Z77A motherboard from MSI

There are lots of different voltages is Vcore the one i'm supposed to change?

And what is the thing about RAM speed that has to be adjusted?

[Maxibonbits]

I had a quick look at the motherboard and it has OC Genie which will make basic over clocking very easy.

Basically all you have to do is press the OC genie button and the system will over clock itself for you.

Heres a video that shows the buttons -

As for really learning how to over clock you will have to do a lot of study and research on several websites until you feel confident that you can over clock for yourself.

I would rather use manual overclocking if possible

Over clocking in a nutshell

Simple overclocking guide:

1. Raise multiplier up slightly

2. Test in Prime95 for 30 mins to see if it crashes.

Intermediate overclocking guide:

1. Raise multiplier up slightly more slightly.

2. Test in Prime95 for 30 mins to see if it crashes.

3. On crash increase voltage slightly until crashes stop.

Expert Overclocking guide:

1. Raise multiplier up slightly more slightly.

2. Test in Prime95 for 30 mins to see if it crashes.

3. On crash increase voltage slightly until crashes stop.

4. Play around with your "bus speed" and "multiplier" until you get your desired overclock with the lowest voltage you can.

Definitions

1. Multiplier * Bus speed = Total CPU frequency

2. Voltage = Adding more produces more heat but makes it more stable. n.b. Its bad to run your CPU at high voltages for long periods of time.

Would not reccomend going over 1.5 volts @vcore for a beginner. If kept there for longer periods of time your CPU will begin to degrade quicker.

wait, ok going into ur bios, how would you find the voltage and the multiplier... how would you change that

What motherboard do you have?

Its usually under an "Overclocking" menu.

[SnypeUXD]

Would recommend once finding a good OC that you run Prime95 for AT LEAST 24 hours to see if any errors occur to make sure your PC is 100% stable.

P.S. This also applies to GPUs too and all OCing should be stress tested before being used normally.

Isn't 1.5v really high?

[tg31270]

So I'm going for a 4.3 GHz Clock with around 1.2v a multiiplier of 43 and a bus speed of 100 mhz

I'll prime 95 it during the night to see if it's stable.

What settings do you use for prime 95?

I have personally gone to 1.52. For 99% of people I don't suggest going over 1.5. So yes that's pretty high

Blend is used most often.

Its under "AI Tweaker" on your board.

i would not recommend going over 1.35v- 1.4v for a beginner. i know for a fact that my core i5 2500k can run at 4.8Ghz with 1.38v - 1.42v so anything under 4.5Ghz only needs some where around 1.3v

blend is ok. but if you are not going to overclock your memory(which if you are a biginner you should leave for another day) you don't need blend. which stresses your RAM a lot. if you are trying to see if your CPU is stable then you the max heat thing.

but like Ghost said blend is the one that is used most.

1.2vcore for 4.3 on a 3570k is more than enough. I'd try 1.15vcore first. Could most likely get away with 1.12v.

what is a safe highest temperature for a 3570k? cause im trying to go 5ghz on it but it goes up around 100c.

Try not to go over 75 celcius. 100C is mad, you will burn out your cpu.
