My_Inner_Fred Posted April 10, 2013 Posted April 10, 2013 Hmmm thats more than enough power and the mobo is Sli compatiable. Have you tried updating the Bios? have u tried both 670s alone to see if they work? Share this post Link to post Share on other sites More sharing options...

Have you tried updating the Bios? have u tried both 670s alone to see if they work? yup they're both working alone.. havent tried going for a bios update though. il try it later when i get home later but if it doesnt, are there any other possible culprits?

d6bmg Posted April 10, 2013 Posted April 10, 2013 Update the BIOS to latest rev and update all the drivers. Report back what happened after that. Share this post Link to post Share on other sites More sharing options...

christopher16ph Posted April 11, 2013 Posted April 11, 2013 thanks guys! did everything you mentioned, replaced SLI bridge, and flashed the BIOS, even changed the power cables just to be sure. its working perfectly now. hmm, planning to make a fresh install of everything since i think i made a mess of those nvdia drivers ) Share this post Link to post Share on other sites More sharing options...
wevsspot Posted April 11, 2013 Posted April 11, 2013 Glad to hear it's sorted Chris. Fresh installs are always nice. It's kind of like putting on a clean pair of boxers after you get out of the shower in the morning (after four days otherwise ) Share this post Link to post Share on other sites More sharing options...
