Hi guys, just wanted to ask whether anyone else had the same problem as me. When i try to oc my 5850's the screens actually flicker a lot. Is this normal? I also asked the guys at xfx support (both cards are xfx) and they said I had to disable overdrive. If anyone could share anything, that would be great. Thanks in advance.

Well before I used afterburner with 1 card. i was able to pull off 900/1150 w/o applying more voltage since its locked on my card. When I added the 2nd card, whenever I tried afterburner it would just lockup and automatically restart. When I used ati's overdrive, even if i adjust it to 730mhz it starts flickering.

using the xfire with eyefinity actually. I was doing fine with the single card but just couldn't help myself and bought me another 5850.

edit: the overclocking part is just the assurance that I can do it if i ever need to do it. You know, its like having a fast sports car and driving it at 90 on the freeway. You know you can go faster but you don't, its just that if you ever need to you know you can. Hope i made sense. XD

edit edit: tried ati tool but I'm getting the kernel error thingy. Running win 7 64 bit.

So you guys really think its the psu huh. It is 700w bronze rating though. Couldn't find actual review on it. But I guess upgrading the psu wouldn't be too bad of an idea. Its just that i just bought the damn thing a few months ago. hahahaha. XD

Donot comment if you have zero ideas about psu and power consumption.A system with 2 5850 and i7 975 consumes about 478 watt.

But i currently have a 700w bronze rated psu. Granted there are not much reviews on the cougar. It also has 30A on each of its rails. There are two rails.
