Updated 680M Bios and no SLI now


Recommended Posts

So I updated to the VBios in this thread http://forum.techinferno.com/alienware/2658-%5Bm14x-r2%5D-%5Bm17x-r4%5D-%5Bm18x-r2%5D-uefi-fast-boot-secure-boot-gpu-issues-%2Asolved%2A-2.html both cards were updated and now whenever I go to enable SLI the system will restart and when entering windows it acts like it doesn't have drivers installed. Help? These are the 680Ms direct from dell

Reinstalling windows from scratch cleared up the problem, possibly hardware address issue or something regarded, because I uninstalled all vid drivers and tried four versions with same result, reinstall windows install latest drivers everything is good again.

Yeah sorry for pointing out the vbios might have been the issue, however it seemed logical, starting with single discrete everything was awesome, enabling SLI and on reboot acted like no drivers were installed at all (Either card). I for sure though that removing the drivers 100%, restoring to a point before I put drivers in for the cards at all, no network so no auto download etc all this in my mind pointed to this on change, but as I said reinstall windows from scratch cleared it all up :)
