Flickering using extended monitors - ATI -

Flickering using extended monitors -58XX -

Ok...well...

Bought a new power supply, Corsair HX 850W, when I was getting problems with my 5970 to replace the Jeantech Modular 700w - I was going to upgrade, now is better time, than any -

But, I still get flicker on the second monitor, when using, extended display and duplicate display, when you drag a window about on the main monitor. I don't get it if I use the second monitor on it's own.

After doing searching on these forums and others, it seems, that quite a lot of people are suffering from this - I'm not sure if this is just a windows 7 problem -

Who else suffers from this ?

And has anyone who did, fix the problem ?

Or, are we going to have to wait for a fix from ATI/Microsoft ?

Your help is very much appreciated. Thanks in advance.

I've underclocked it, still happens.

Use http://www.techpowerup.com/downloads/1641/AMD_GPU_Clock_Tool_v0.9.26.0_For_HD_5870.html to set clock speeds, this will disable powerplay, see if it still flickers, make sure you don't have any other OC software running when using GPU clock tool.

OMG !!! Flickering has stopped !!

Nice one mate.

But this is an overclocked version from sapphire ?

What should I do ? Ask for a normal clocked one, or wait for drivers, if you think ATi will sort it ?

What is the cause of it ?

Thanks mate , you're a star

Edit. An overclocked card has nothing to do with the screen flicker, its ATI's powerplay feature causing the issue so it needs sorted their end.

You'd think selling a half a grand card they'd have sorted it before hand

Anyway, cheers mate, top man.

This was driving me CRAZY
