Risk on Clicking " Auto-Tune" feature on ATI Overdrive(tm) for my PC??

[merosansar]

Hello,I have ATI Radeon HD5450(Fanless). Is there any kind of risk to click "Auto-Tune" button, found in the ATI's CCC, for my PC?
What is the maximum safe temperature??

There is 0 risk but having a 5450 there will be no advantage to it.
Just more heat.

5450 is not a gaming card, only HTPC purpose, so you'll be wasting your money and time to overclock that card. Your card is FANLESS, makes it theoretically impossible to overdrive... Anyway, you will gain a very very little performance increase even if you manage to OC that card.
