Power control settings in CCC Values?

[Buchanan0204]

Hi there,

I am in the process of overclocking my 6970, I am using CCC. I was wondering what the recommended Power control settings was? It ranges from -20 to +20

I am a graphics card novice. Thank's for any advice given.

Cancel that. I set the values to 950/1450. However it crashes when trying to run Heaven benchmark, "display driver stopped responding and has recovered" Why can't I get a stable overclock at these settings when everyone else can straight out of the box?

Am I missing something? Am I supposed to blend in the Overclock gradually like I would with a CPU overclock? I was under the impression I could just crank it up.

To get my 6970 to overclock to 950/1450, i had to increase the power to +10, and set the fans to 48% when in game, to stop any driver crashes. Try that, but if that doesn't work, maybe you will need to wait for the next set of drivers, I've been having overclocking troubles myself which I think are software bound tbh

Smashing I'll try that, thank's very much.

In short what exactly does power control actually do?
If I add 10% what exactly does the 10% consist of and do ?

I think "but don't quote me" that it increases the maximum power that the card can draw. This is useful when overclocking by small amounts because it stops you from going to far with voltages and what not.

Say if your maximum power consumption at full pelt at 0% is 280W, whilst your overclock needs 300W, the +10% will open up enough wattage to safely carry out that overclock without the card throttling or your display drivers to crash (Which is what was happening to me)(Also, these numbers are just for example, I know they may not be correct)

Problem is, that the power control is absolutely no use outwith your standard overclocking range, and is disabled when trying it with a program like Afterburner

So power control only works within the default and max allowed within ccc?
Is that what your saying?
Why on earth did they only allow such a small official oc ?
