Overclocking gfx 275

[Slinkie]

Hi Folks,

I want to overclock my 275 but for some reason I can't in riva tuner v2.24.

In the driver settings it says "No supported drivers detected for this display adapter".

I have vers 190.38 installed.

I can I fix this, do I need an older driver version?

cheers for that, got it working now

One thing that is puzzling me is the fan for the card (ignore my ignorance with aircooling, my old card was watercooled from the start so I don't really know about fans etc).

From what I can see in Riva tuner the fan always runs at a constant speed. I have it set to 50% at the mo as that's a good compromise between noise and cooling. However, is there anyway to get the speed of the fan to change with temp of the card. For example, if the temp goes over 70 degress increase the speed of the fan to 55% etc. That way it'd be quiet when I am just browsing the net and then louder when I am gaming (I wouldn't hear it then anyway as I game with headphones).

Is there anyway to do this?

Try this:-

Set 3 fan speed profiles for low, med, high temps. Just depends on what ºC you set. Then it'll adjust automatically when it reaches the desired temps.

Use EVGA Precision to overclock the 275. Its very simple. I use it.
