Dual Graphics set up in an Alienware m18X R2

[suteck]

I have a dual gpu set up (7970m) and the primary card started putting lines in the display. I removed the card and moved the secondary into the primary slot. After boot up multiple times the bios and operating system recognized it and all was working. My question is, if I put the first card in the second slot will it work again in Crossfire mode? Does it only use the graphics processer and will I get the boost of Crossfire again or will is start putting the lines in it again?

Thanks

Nope, Screen remains black after initial boot. Remove the second card and all is good for single card. You can use the second card from slot 1 in the first slot, (slot 0). But apparently once your video card starts putting lines on the screen it's time to sell it on Ebay "as is" lol.
