Scroll down to OverDrive5 (towards the bottom)

and change the Want_0 to something higher (I would say 500 instead of 300) and save and that's it.

He probably means screen flickering. I had the same issues in xfire 5870's when one card would drop to 100/300 for some reason. It cause 2nd screen flicker and even 1 screen flicker in the right (wrong?) conditions.

I thought that as long as a video card can run a game, and all settings are the same, there should be no difference in image quality. Like if I were to compare a 570GTX to a 6970 and said the 570 ran BF3 more beautifully when they both look the same. Sorry, no sarcasm, I'm just wondering if it really does improve image quality, I might try it out. It's because my drivers are stable now and I know how unstable installing/uninstalling AMD drivers can be and I don't want to mess anything up if mine are working fine right now, but if it does improve image quality and eye candy...

I wouldn't pin it as a placebo effect. I do notice smoother gameplay, and the graphics haven't changed so much overall as being any better than how BF3 was designed, moreso the look/texttures/shadows seems a little better and 'clearer'. Of course drivers CAN actually make a difference. If you'll notice in the CCC settings panel itself even, there are sliders to change graphic rendering settings to: 'Performance, Quality, High Quality'. While they won't make a HUGE difference, there is a difference. From a card like the 6970, to the 580 and the 7970 - there are differences between cards as well. The 6970 series of cards had bad Anisotrophic filtering algorithms which would cause 'flcikering' in the distance of scenes etc. and not quite as good anti-aliasing, with a larger performance hit as well.

So it's not a placebo in this case anyhow I don't think... sometimes an extra 2-3 FPS in worst case scenarios, or a driver fixing some latency issues etc. will smooth things out in a way that you notice. For instance, if you run with VSYNC on all the time (as I do... I hate screen tearing) sometimes that couple extra FPS or reducing a bit of the 'worst case scenario' with better optimized drivers is enough to pin it at that key 60fps+ mark and have it stay there. Even only a couple FPS can make the difference here in overall smoothness.

put some furmark test for an hour or two to check your stability and temperature.As i know overclocking core clock speed and memory speed require some voltage up (what u did) and voltage upping can move your temperature up,so put some test to see what is max/min/avg temperature...for anycase

Trixx doesn't need to be running in the backgorund, just open it, set your OC profile and it only applies them to 3d performance mode. You can then close it if you wish and you will see when running any 3d application that your OC is applied, when not runnig 3d you drop back to 3d low power then 2d clocks fine.
A reboot, or opening the program and hitting 'reset' will return your 3d clock to defaults.
Simple, effective and doesn't interfere with powerplay. I've set mine to +20% and just left it there.

Problem with rebooting is that your previous settings of Trixx are still stored in CCC Overdrive, I have CCC on at bootup so when rebooting it turns back to the overclock BUT without the voltage increase, making the system unstable.

So you have to remember to go back to default clock settings in Trixx after gaming...
Bit of a pain but oh well ...

Also I read somewhere the folowing :

Is this correct? So if you use 2 HD7950 in crossfire WITHOUT using AB or Trixx it is best to leave ULPS ENABLED ?
Thanks for the replies !

Nobody knows this?
Thx in advance!
