990FXA-UD7 fails to post with SLI video card

990FXA-UD7 fails to post with SLI video card
« on: November 14, 2011, 09:40:17 pm »
Has anyone been able to get this motherboard (out of the box) to post with an SLI vieo card? 

When I try the cpu fan goes on high and never slows down as normal when the posting starts - the onboard error numbers is just a single zero.  If I take out the video card I'm assuming it posts but I have no display to confirm as the fan slows down like normal.

Gigabyte says to enable SLI support you need to update the bios, have an SLI card and drivers.  But does that mean you need a Crossfire X card to even get it to post so you can update the BIOS?  It would seem very strange for the box and online to say 'SLI Ready' when it really means 'SLI Ready only when you have used a Crossfire card to post and flashed the bios'.

Hopefully I'm wrong and this board can post with an SLI card so I can update the bios to full SLI support as I dont want to buy a crossfire card to get this thing to post.

VideoCards tried (Asus - EN8800GT, GTX 280)
Ram: Mushkin Frostbite PC3-12800 4x4gb
1000w power supply
AMD 1100T Processor

Thanks.

As you are only using one card you dont need to enable sli till after the post so it is a different problem than what you think it is. When they speak on enabling SLI with a bios update they mean to enable more than 1 sli cards. Start with bare requirements. cpu and fan, 1 stick ram and dvd drive and hard drive with video card see if there is any difference.

Thanks for the response autotech - I finally gave up after trying your suggestions and took the computer to get checked out and it appears the new MB is toast.  So as you expected it had nothing to do with the SLI.  Waiting for a new one and hopefully all will be good.
