tampering with clock speeds

([msg=39057]see tampering with clock speeds[/msg])

Just wondering
Is it possible to write a program that is able to ,for example change the clock speed of a processor, or the speed of your cooling fan?

And if it theoretical is possible, did you ever write one?
and in what language would you write it?

my ASRock motherboard came with a program that does just that. Called OC(Overclocking) Tuner. It works but twice I've tried to use it and twice I've nearly damaged my processor....

I know it can damage processors etc. I'm just wondering if it is possible and thanks to your post I know it is, now I'm just wondering how the **** someone would program that( not asking for spoonfeeding, but some lecture of some sort could be nice)

I would think that it definitely would depend on the motherboard and processor. I doubt every mobo and processor would let that happen. Imagine if someone made a virus that would automatically overclock it. Tha could cause millions in damaged processors.
The glass is neither half-full nor half-empty; it's merely twice as big as it needs to be.

Yeah its possible but it doesnt matter which processor is on this motherboard you could overclock with whatever (processor), I tried to speed up an emulator because I lacked a proper Video Card. When it maxed out the whole pc freezed then the monitor acted erratic so I had to cut the power supply in case the processor got damaged. Its not worth it if you ask me and if someone did write a custom script to do this it could do some serious damage but Im sure the manufacturers are aware of this and take precautions against it.

Also mobos and cpus will shut off if either temperatures or voltages reach dangerous levels.

That doesn't stop them from possibly being damaged though.

To be honest I have absolutely no clue how you'd do this. I'm guessing it might be possible with some fairly low level programming. I doubt anything like this would work at an O/S level though. Most likely, you'd have to write something that edits the bootloader so that it executes your clock speed tampering code before it moves onto the O/S and all the tons of extra protection that would no doubt provide.

I certainly think it depends on motherboards and BIOS as well. I can't imagine there wouldn't be some kind of protection past the standard temprature and possibly voltage ones (which I've never heard of, but I'll take Candles word for it).

Thx insomaniacal, your the first one that actually answered my question :P But from your answer I can see its way over my head at this moment. thx anyway

No problem. I'm not 100% sure of the validity of my claim of extra O/S protection, but I'm assuming most modern Operating Systems wouldn't allow such direct access to the processor.
