How to Overclock Your Laptop's Graphics Card

Picture of How to Overclock Your Laptop's Graphics Card
If you're at all into gaming, there's plenty to be gained by overclocking your graphics card (GPU). With some luck you can boost gaming performance and frame rates by 20 % or more, making a previously unplayable game playable or allowing you to turn up the details in demanding titles. There is usually little risk involved, but you have to be aware that by tweaking the hardware settings you are stressing the components beyond their specifications. Consider this a fair warning and follow these steps at your own risk!

Prerequisites

What you need to overclock your laptop's GPU is first of all a laptop with a dedicated graphics card. Don't bother trying to overclock a laptop with an integrated graphics chip from Intel such as "Intel HD graphics", "GMA 4500mhd" or anything of that nature. Only dedicated chips from AMD or Nvidia are eligible for overclocking.

Different tools are at your disposal for overclocking, and it can (usually) all be done with software solutions. The exception is when the manufacturer has made the unfortunate choice of locking down the card in the BIOS to prevent overclocking. You can use most of the same tools for laptops as those you would use for overclocking a desktop graphics card. You have to keep in mind, however, that the space inside a laptop is restricted and a laptop GPU is likely to overheat faster than a full-size graphics card in a roomy desktop computer chassis.

Step 2:

Upping Those Clocks

As for the aforementioned overclocking tools, there are several good ones--even official varieties from AMD and NVIDIA. If you want to browse around, visit Guru3D for a more or less complete list of downloadable software (most of which are freeware). For the sake of this demonstration we will use eVGA's Precision software, which is very easy to use. It's branded and created by eVGA for use with the manufacturer's own graphics cards, but works equally well with other cards and even laptop GPUs.

The simplicity of this tool is admirable; you can adjust the core clock, shader clock and memory clock separately, with an option to link the shader and core clocks (recommended). In most laptops, the fan speed is controlled by the BIOS (the computer's firmware), so this option will be grayed out.

Now you are free to start adjusting those clock speeds, but be careful! Raising the bar to high will cause your system to hang and/or overheat. It's highly recommended that you raise the clocks in small increments and test the system for stability in between the clock increases. You can probably safely raise the clocks by a larger amount, say 50MHz, the first time around, and then up them by 10MHz at a time, testing for system stability between each increase.

Step 3:

Testing and Some More Testing

Just increasing the clock frequencies of your laptop's graphics card and see whether it hangs or not won't do you any good. Unless you have tried it "for real" you have no way of knowing if it works at all in actual games, and perhaps more importantly if it is a stable overclock, i.e., that it works consistently when gaming for hours on end without crashing or overheating.

A couple of good programs that are specifically designed to stress test your system are Furmark and Futuremark's 3D Mark benchmarks (see Guru3D for these downloads as well). Furmark is freeware and very simple--as the name implies it animates some "fur", which is apparently a tough task for any graphics card.

3DMark on the other hand, is not freeware but available in shareware versions. This is arguably an even better option as it simulates the workings of a real game. It can also be run on a loop, so if your gaming laptop manages to run one of Futuremark's tests for several hours without any issues you have a stable overclock.

You don't just want to know if it works at all or just hangs--you should also watch for artifacts on the screen (strange lines or other quirks in the rendered video), which would signify that your GPU has passed the limits of its ability.

Example

To get an overview of how gaming laptop overclocking works in practice, have a look at this Alienware M14x overclock . This laptop uses the NVIDIA GeForce GT 555M, which is a rather common graphics cards in current laptops. As it turns out, it is possible to push the GT 555M to provide a 20 to 30 per cent performance improvement--one that is clearly noticeable in your games.

Please remove the part about 'Intel HD not being able to play demanding 3D games'. I have a Toshiba Satellite with an i5 (HD Graphics 4000) and no further GPU, and I am able to play Skyrim at over 30 FPS on med-high settings, well over 40 on med. Just thought I'd share this. Bet some people are let down by step 1 ;-)

Try to play fifa 14 while using the integrated gpu, it is not a good idea.. i have i5-3210 with nvidia 7670m

I totally agree, I'll remove that part. Thanks for pointing it out! In my defense, it was written when Intel IGPs were mostly useless :)

30-40 is too poor for a decent game experience 60 fps is what everyone hopes and most of the time you wont get that with intel's integrated graphics, not to mention that if you like a bit of old and good games like rise of nations or arcanum many of those intel graphics wont be recognized as valid external graphic card and wont run.

30 is not poor at all. Have you ever played a console game before? It's pretty standard. Maybe certain games benefit from a faster fps but in general it really doesn't stop me from playing.

i have an nvidia 710m 2gb vram ddr3,and when i take the last driver for nvidia official site,i was downloading those tools,u know?? But for my laptop it doesn't help the overclocking,u know,i mean is not even one difference betwen then and now with increase these values and i wanna say that i double them and still no difference!! The games runs the same,with some issues,some fps drops,but playable in some games!! Anyone can tell what i do wrong? Why i don't see any difference!??

The thing is nvidia 710m is not suitable for gaming or rendering purpose. Thats why you get lower frame rates. 710m is capable of multitasking and watching videos or movies.

Hey everyone! I had a question. I have a Dell Inspiron with an i7, 16gb RAM that clocks about 3.1 GHz. It has a pretty nice GPU, which is an Nvidia Geforce GT 750m. I am able to play GTA IV with iCEnhancer, and xliveless. I am able to run the game at about a playable, but not to good 20 FPS. If I were to overclock it just a little bit, would I be able to at least run it at a constant 30 FPS?

If you are seriously considering overclocking your laptop you might want to apply new thermal paste to the GPU and any other chips that share that heat sink. The thermal paste that most manufactures put on is messy and inefficient. RadioShack has Artic Silver which is very good.

Well, like it says in the opening paragraph and warnings throughout the article it's at your own risk and overdoing it will definitely result in crashes, even if it doesn't permanently damage your laptop. Nevertheless, I've overclocked dozens of laptops with no permanent adverse effects and people do it all the time - even some professional gaming laptop vendors ship their laptops "factory overclocked" (after rigorous testing and "burn-in"). Also, graphics card vendors usually ship their graphics cards with tools like the one above from eVGA, essentially encouraging overclocking. The same principle applies to laptops, but you have to take much greater care considering the heat constraints and watch the temperatures closely. Needless to say, if you feel uncomfortable doing it then steer clear of overclocking altogether.

This doesn't seem to be a good idea to do.
