Hey guys.
A few days back I decided to purchase a 2nd 7950 (r9 280, from OC; http://www.overclockers.co.uk/showproduct.php?prodid=GX-019-VX) for my PC, looking to crossfire, however upon installing the card my monitors don't work.
This might get confusing, so 'Card 1' is the original 7950 I had, with 'Card 2' referring to the newly purchased r9 280.
I tried all of the following with the use of both my monitors, then switching between using just 1 or the other, testing in all available dvi ports (on my mobo, card 1 and card 2).
What happens is my monitors just blank out, saying 'no signal' the moment I attempt to add card 2 to my machine. Here are the various things I have tried and nothing seems to work;
- Every possible combination of Card 1 and Card 2 slotted into the PCI slots with the crossfire cable connecting the two
- Using just Card 2 on it's own in every single PCI slot
- Switching the psu to gfx card pci power cables to others; tested and working perfectly fine with Card 1
I am confident I am fully seating the card on the mobo and that the power cables are all the way in too (having spent the most part of a day trying to sort out this issue).
No matter what I try, the monitors state 'no signal'. The fans on card 2 power up and the fact that the even when Card 2 is installed alone these issues remain suggests that it can't be a power related problem.
Is the card just 'dead' or am I doing something wrong? Any help would be greatly appreciated.
Was ideally hoping to get this sorted out prior to i52, but if need be I'll just get a replacement card there if I have to.
Current build if it helps at all;
- i7 3770k (standard clock)
- VTX3D 7950 (standard clock)
- 1 x 256gb SSD
- 2 x 2TB Barracuda HDD's
- 2 x 8GB RAM
- Gigabyte Z77X-D3H Intel Z77 Motherboard
Thanks <3

Are all your drivers up to date? Could be that something on your system is outdated and not recognising the card.

Aye, I updated everything I could.

Considering card 2 doesn't work on it's own in any PCIe slot it might be dead.

Try reseating the ram or resetting the CMOS battery.

Probably should have updated this earlier, but I managed to get it working yesterday.
I updated the bios on the motherboard to the latest beta build and it seems to have done the trick. However now, when I try and launch Sim City (whilst crossfire is enabled) I get BSOD's; works fine without crossfire enabled. Issue is, every time I disable crossfire, I get a BSOD anyway...
Also have this really weird glitch on edges in every game I've played so far (CSGO, TF2, Arma 3), where upon moving my mouse or character the edges almost have a 'double shadow' on either side of them, where one 'shadow' is lighter than the texture and the other 'shadow' is darker. It's not overly noticeable, but get's pretty frustrating....any ideas? (Disabling crossfire here doesn't seem to work and I've fiddled with the catalyst control center game settings too).
