Guys need some help after swapping around my 7950s to different PCI sockets

Hi chaps

Just added another Sammy Evo SSD in my rig today, while I was in and around the motherboard, I decided to have a dust and thought about moving my 7950s the other way around to see if I had any different temperatures. Not that they were getting hot or anything, just the curious side of me getting the better.

Now upon restarting the PC all my CCC custom profiles had disappeared along with my MSI Afterburner profiles etc. So uninstalled the drivers and reinstalled them along with resetting all my overclocks up. Now, decided to try and run valley to bench to make sure things are ok, but no. I get a black screen then pushes me back to desktop where im looking at the Valley setup page, but in my task bar I have the valley test running but tabbing to it is just a black screen. Exactly the same thing happens with Heaven. Also, I tried BF4, it displays the game in windowed mode but it wont display in full screen. If I ALT+ENTER it tries to get it full screen, flashes and goes back to windowed mode. When I try and deploy, it attempts to go full screen, but then flashes back to windowed.

Previously, I had the ICEQ-BOOST in PCIEx16 slot and was my primary card and my Gigabyte Windforcex3 as my secondary card. So swapped them over vice versa now.

Any idea what the freck is going on?

Ok got things working ok visually, but something is definitely not right.

I just benched Valley, both cards being used around 99% but with a result of 2756..My best with exactly the same overclocks on my previous config with the cards around the other way is 3570 points and is on the leaderboard. 800 points difference is huge, any ideas why? Only thing that might be different is the driver, I'm using the latest BETA 14.7, any known issues regarding bad performance numbers? Also, my 3570 benchmark was on Windows 7, obviously now I'm on Windows 8.1, would this have any effect on that 800 lower benchmark?

Not played any properly as of yet. Just had dinner will try again in a minute. Was just wondering at the table, with the extra ssd, I wonder if I'm pushing my 850w OCZ psu. I have I7 at 4.6ghz, 2 7950s at 1100/1500, 16gb ram, 2 Sammy EVO ssd, 2 1tb hdd, 3 120mm noctua fans, 3 80mm noctua fans, and a dvd drive. Do u think I might have pushed my wattage to the limit with the extra ssd? Maybe causing the cards to not get enough juice? Will unplug the ssd and test shortly easy test.
 
Doubt it's a power issue. If it was the system would likely shut down due to the psu drawing too much. Iirc, LtMatt ran xfire 7950's with a 5.0ghz 2700k cpu on a 750w psu without issues.
 
ok cheers guys..will be an easy test to do, will just get in and disconnect the power to the new ssd and retest.

Touching on the Windows 7 v 8.1 bench, you say Windows 8.1 not as good as 7 Petey, do you think 800 points difference? that's a massive number.
 
thats better :) :)

First of all glad you got your issues sorted :) secondly, may I ask what 7950s you have? I just ran heaven valley with my 7950s at 1150/1450, and 2500k at 4.5 ghz which I use 24/7 in summer as I'm air cooled. And I got 87.1 fps average. And I ran at 5ghz and I got 87.5 average. My cards are sapphire vapor-x cards. I'm guessing heaven valley isn't really cpu heavy otherwise your score would be a lot better than mine with a 3770k
