Windows 7: Does AMD Overdrive automatically adjust voltages?

Does AMD Overdrive automatically adjust voltages?

I recently received my new AMD 7950, part of the drivers package is the catalyst control center, like the nvidia control panel. There is one section in it which manages performance, it has an overdrive mode. So while in idle the card clocks itself at 300mhz, when being used intensively, e.g. by a game it will clock itself to the max stock speed of 900 mhz, however it can go higher, all you have to do is slide up the slider corresponding to clock speed and next time it hits overdrive mode it will clock it to that speed...supposedly.

So..If I just slide up my overdrive core clock 50mhz or so, and believe my cooling can handle it (its 33 idle, 50 80% fans on 36%), is it that simple? Does the card handle any voltage adjustments and such? Or is it more complicated than that?

Hi.

Usually the drivers in the gpu package are outdated,so is better to download and install the most recent software\driver,catalyst from here,

AMD Graphics Drivers & Software


Your AMD 7950 is powerful enough to handle almost anything.


So you dont need to use the overdrive or any overclocking.


If you just increase by 30-50 in gpu and ram clocks then you dont need to change any voltage.


With 30-50 you will not see any improvement anyway.


If you want to add 100 and more clocks then you will need to adjust voltages for stability issues and adjusting voltages is not a good idea especially if you are not an advanced user .


My opinion don touch anything,ok almost anything,you can adjust freely the fan control

Yup, mostly what I expected. This is more a thing of curiosity than anything else, I have been over the pros and cons of over clocking and have no real need to at this point in time. I was simply wondering if it might be for once a truly simple overclock, but there is always a catch isn't there :P

Hi everyone, about 3 weeks ago I got a random BSOD whilst alt-tabbing out of a game (DOTA2) something I'd done quite a few times before with no issues. I scouted around and noticed mention of bad nvidia drivers burning out cards. These were the drivers I had installed so I rolled back to...
