Read some of these post http://www.overclock.net/newsearch/?search=flicker&output=posts&type=all&containingthread%5B0%5D=1318756&advanced=1

if you only play skyrim then you might be best off using 12.4 driver.

I will look into this

2 power supplies are badbadbad

almost sure that ultra 550w is group regulated, not a quality power supply to use for dual PSU'ing

I run the 550 on separate line for all of my watercooling equipment it has no interaction with the pc itself

13.1 and 12.11 CAP 2

You could try to pump the voltage to 1200mV or something and see if that helps.

I have no option to adjust the voltage on these 7950s


Thanks for all the reply's guys

Well I poked at the drivers some more and I am calling it this is not a pleasurable experience, I am fighting a debilitating problem rather than gaming benching etc thumbsdownsmileyanim.gif. I really wanted to like these cards but I cant take something this broken and hope that they have a fix in a few weeks. The more I read I see people have been waiting for a year now and there is till no word on what is happening. So I will pop my tri sli 470s back in a wait for something with the vram I need that is also stable which unfortunately rules out all currant gen cards from both teams (with nivida lacking in the vram department and amd having these problems).

I would use those 470's as long as you can. Get a 780 or 770 in 3 to 6 months, it should be pretty good. They said 780 with have 6gb of vram and be 85% the speed of a 690. So almost as fast as two 7950's in crossfire on a single GPU.
