How To Overclock CPU/GPU?

How exactly you overclock your CPU depends what it is, there is a general guide here: http://www.ocforums.com/showthread.php?t=263753 and loads more general information in those forums.

Your GPU is easy, just download ATItool (http://www.techpowerup.com/atitool/) or similar and move the sliders to increase core/mem speed. You should do this in small increments, testing for stability between increments, when it becomes unstable, drop it down to the last stable setting and bosch, you're done.

The better your cooling is, the more you should be able to overclock (though this is not always the limiting factor). Extreme overclocking could possibly decrease the lifespan of your components, but the person who claims it can make your PC a fire risk clearly knows nothing about the basics of computers. I overclock all my hardware, simply because it is performance for free, and have never so much as damaged a component.

Wow, 2 thumbs down for being right... You cannot "explode" your CPU, any CPU from the last 5 years has thermal overload protection built-in. This means the computer will totally shut off when the temperature reaches a certain level (less than 100C), obviously the point of ignition for anything in a computer is well over 100C, therefore, no fire or explosion risk.

Heat does increase (linearly with frequency, exponentially with voltage) ie. increase the speed by 20%, heat increases by 20% increase voltage by 15%, heat increases by 32%. (the new core2duos use less than 100W, so we're talking a rise of only a few watts here) As I said before, you need to be doing extreme overclocking to see any significant heat increase.

Liquid cooling is not required unless you are doing more than ~50% overclock, which most processors aren't capable of.

Even if your BIOS doesn't have an option to increase the FSB, there are windows utilities that will let you do so (see crystalcpuid, rmclock, 8rdavcore, speedfan, etc).

Most processors have at least 10% headroom, meaning you can increase the speed by 10% by just upping the FSB and changing nothing else, this is basically free speed.

If you have more money than sense, then yes, you can just buy faster components, seems silly when you don't have to though.

Do some research, read opinions of people who know what they're talking about, not the muppets on this site, then make your own decision.

LUg, the facts are plain, and are easily confirmed from multiple different sources. What makes you think that you are an authority on something you have never done? Saying that overclocking is a fire risk is like saying running Linux is a fire risk, it belies an incredible ignorance and lack of basic knowledge. Do the research, then come back and edit your answer to be factually accurate .

Sadly the fact that you have 3 thumbs up merely shows how uninformed other users of this site are, that is all. I'm sorry that you are too stubborn to try and increase your knowledge-base, but everyone else knows you cannot make your PC a fire risk by changing software settings...

The only things you "always" start with is disabling CPU spread spectrum and disabling PCIE spread spectrum. Also set PCIE to 100mhz manually (not auto). These are safe and recommended for any system. In general I up FSB first and dial in the maximum speed my ram can handle and be stress tested. I manually set RAM timings but I just use better quality ram and I'm fine with the manufacturers timings. Then I up CPU multiplier and stress test that. If I'm not getting similar speeds to what others are on that specific CPU/RAM I look into the fine details like voltages, LLC, C states, APM, HPC, etc. A lot is specific to your BIOS and features there. Only touch voltages if you have to and only as little as you have to. Seriously though I would take note of every little setting you have available in your BIOS and reading up on them and exactly what they do. Once you understand what all the little things mean you will know what to turn off or on, how safe it is, and if it's even going to make a difference.

For your graphics card, use ATI tool or rivatuner.

For your CPU, you likely can't unless you built your PC yourself. Check your bios settings, if there is nothing there, you ain't be overclocking it. That's because computer manufacturers don't want you to.

I agree with Linux Ubuntu Geek, overclocking isn't the safest thing to do. And the performance increase is miniscule compared to just upgrading your hardware. Before doing any overclocking, put a nice liquid-cooling system in there. Overclocking will make your computer run much hotter that normal.

If it gets hot enough, your processor can even literally explode

I am no expert on overclocking, only that I know you have to know what you are doing or you can severely damage your PC, at worst create a fire hazard !

Good luck.

I have been working with computers ie. servicing and building them for almost 15 years, so I would consider myself qualified to make the 'fire hazard' statement, which by the way is FACT !

It is people with an approach such as yourself that should be made aware of the true risks that overclocking presents.

Once again I reiterate my statement that overclocking of PC components can indeed, unless you are careful create a 'fire hazard'. I have no idea at all why you would blindly lead people in to thinking it not to be the case and, also may I say irresponsible of you. This site is for helping others and supplying accurate information, and not a site for childish name calling.

My answer stands end of, afterall I am the contributor with 3 thumbs up, that alone speaks for itself.

Marc S

This is all becoming rather tiresome, so shall we agree to disagree. This site is not for arguing. My original answer stands and this is not due to stubborness this is due to fact !

May I take a moment to apologize for the disagreement that has taken place between Marc S and myself, such issues should be solved on other sites.

Intel turbo boost.! u can speed up the CPU speed. and Razer game booster will help up little bit for GPU

I've created a few tutorials which should help:

CPUs and RAM: http://www.cyb3rglitch.com/Overclock-CPUs-RAM/How-...

GPUs: http://www.cyb3rglitch.com/Overclock-GPUs/Overcloc...

The GPU one isn't finished yet, but only the BIOS flashing part isn't done (which is a bit advanced anyway).

Hi,

Here you go, all you ever needed to know about overclocking.
