GPU clocks vs Temps.

Im just a little curious to know.

if a good temperature is fine (ie: mid 70's)---> while gaming.

Would it matter if my clocks were set to...say, 750/800.

If i still got a cool temperature, would my GPU still be able to operate? or do the clocks have to be somewhat not to exaggerated?

Cuz i tested my clocks with 675/731 and they are fine...bout 77C.


Will it melt in other ways then the temperature?

 

At a certain point, the transistors in your GPU wont be able to move any faster, and you'll have to lower the clock speed to something reasonable for it to work. That said, as long as your temps stay decent (I'd say below 80 Celsius on a laptop is great), you can try pushing your clocks a little bit higher without too much worry.

These cards are technically rated for temperatures up to 125 Celsius, they generally never reach that temp though, usually the computer will autoshutdown to prevent damage before that point.

 

Ahhh i see. so the GPU itself will just stop working? as in...cant process any faster than that.. even if the temps are like 79C?

 

Yea. Try setting a really high clock, say 650/950 then start running a 3D program. Chances are, your screen would start acting funny, like it may keep flashing, or white spots would appear, etc.

Otherwise, as long as the temperatures are still within resonable standards, it's fine. Heck, there're times when I overclock and it's cooler compared to when I underclock, simply because my fans can't be bothered to kick in if my CPU isn't under load.

 

If you're temperatures are reasonable for an overclock (<80C is fine), then you shouldn't worry about the overclock "melting" a GPU. The most that can happen is that you find your chip's specific limit indicated by BSOD's, crashing, and artifacting. Depending on what game you're running, this limit could be at different levels. Simply running at a higher clock speed won't do damage unless you're talking about increasing voltages to make it stable or something.
