Yes... that's what people don't seem understand. Just increasing the speed doesn't hurt anything directly. Increasing the voltage can, and it getting hotter can.
*EDIT* On the other hand... putting an nVidia heatsink on an ATI card which doesn't make contact with the core will definately damage the card and is pure stupidity and should not be RMA'd.
agreed
Actually, power consumption for most things will increase with clock frequency, but increases roughly with the square of voltage increases.
The reason OCing without voltage increases is unlikely to break anything is that the part is likely to simply 'not function' at high overclocks, and therefore not get hot.
If you had a part with one weak link to act as a fuse, you could indeed break it just by OCing it.
In practise, it is indeed unlikely that this will happen without voltage increases or physical modification to the part. When I say I won't OC anything with a warranty, I consider that:
1. Getting a meaningful OC from most parts requires more voltage or modifications. Even a seemingly tiny voltage increase can have a very large effect on the power dissipation of the part, especially when coupled with clock speed increases.
2. Even if I get a good OC with no modifications, I'm still running the part out of spec. This even applies if I buy a 2500+ Barton, and a great cooler, and then run it as a 3200+. It uses more power, even at default voltage. I might consider buying one of these and doing this, and if it broke immediately when I tried to boot it as a 3200+ I might come to the conclusion that it was defective already, since this definitely shouldn't happen, but if I had been running it even for an hour or two before it broke, and even if the temperatures were nice and low, it's me that is SOL if it breaks, and that's how it should be. By purchasing a cheaper part, I'm also choosing to self-insure against product failure. AMD offers a part with a warranty at 3200+. It costs a lot more; I could buy two 2500+ Bartons and still be ahead money; if I'm forced to do so because OCing causes the chip to fail, it's my own damn fault!
Companies that support OCing under warranty are changing their warranties to meet customer needs and wants; there's nothing wrong with this, but those policies only apply to the parts they apply to. We as consumers should not feel we can re-write warranties at our leisure.
