GT 9800 GX2 issue

Hello toms,
After I bought this card as broken, i per usual cleaned it in detail, re pasted new pads turned out to be working.
On first boot in device manager after installation (Win10) showed up 2X 9800, but after one try of starting game it froze (hard), force shutdown, and started up, the second gpu isnt showing up but one as 9800Gx2 , no option for SLI in control panel, nothing..
I hope that I didnt killed the card.
The led indicates Green and blue, blue as Active , green as?
And yes pre driver install it showed 2 cores in gpuz
