Is it safe to overclock my gpu?

I don't think overclocking your GPU will make much difference to the amount of memory you have. It may improve the speed, but a lot of extra memory won't appear out of nothing ;)

Besides, overclocking your GPU (or CPU) too much will probably - most certainly - result in it being rendered unusable.

"Fried", as Ryu calls it.

1. Overclocking has nothing to do with the amount of system RAM that's being dedicated to the intergrated video.

2. Most computers with intergrated video have a base amount of system RAM that is always dedicated to the GPU, and there's usually a max amout as well. What happens is the the system RAM is allocated dynamically on an as needed basis without any imput from the user, the amount allocated will depend on load and the type of application being run at the time. For example if you're typing something in Word then there's very little load so the system will allocate a low amount of system RAM for the GPU. But if you run a 3D app or game, it will allocate more system RAM

3. Some computers will allow to change the max amount of system RAM to be used at VRAM, this option is usually in the BIOS

4. usually you can't overclock intergrated GPUs effectively. As I stated above, overclocking has nothing to do with amount of VRAM a GPU has, but rather you're increasing the core clock speed and/or the memory clock speed, Obviously on an intergrated GPU fooling around with the memory clock speed can lead to instability because intergrated GPUs don't have dedicated memory, they use the system RAM as VRAM.

I'd like to address a hilarous answer made by another responder.

"So you shouldn't overclock over 281MB. "

Holy crap, if that's the kind of information you're going to give, just keep it to yourself. Overclocking has *nothing* to do with the amount of RAM or VRAM you have. If I have a computer with 8 GB of RAM , I can't overclock my way to 16 GB. That would basically break several laws of physics.

First off, if you are planning on overclocking, you should look up some guides, it can be dangerous if you don't know what you are doing. Check out overclocked.net, it has good information.

Secondly, it is not possible to overclock a card to have more memory. Only to be able to process information faster.

Also, you really can't overclock a laptop gpu, there might even been locks on it to prevent it from doing so. If you want more vRAM you need to get a new computer.

No, it's not safe.

Overclocking GPUs can be fine, but not to the extreme you are doing.

In general, it is never good to overclock more than 10% of your base.

So you shouldn't overclock over 281MB.

Attempting to quadruple through overclocking will fry your GPU and you'll have to buy a new one.

no not unless u know what your doing

no but it will probably be bad for your OS
