I have a thought in mind that no one seems to have suggested yet, but it flies in the face of all I've said about the Ultra D, and that is perhaps it's necessary to run the two video cards with the SLI bridge in place. This is counter-intuitive to me, as I believe the SLI bridge is only necessary if you're running in SLI. Since this is an Ultra D, logic and intuition say that the SLI bridge is unnecessary. But it's something you can try.

Having two cards in, in non SLi should work just fine.

On my EVGA 590 SLi, I was able to have 2 8800GTS 640's in with no SLi bridge folding just fine.

I love that Foxconn board. The BIOS is alright. It over clocks well. Though, that DDR3 I have really holds it back.

Some lower end cards of each (I think the 8600 GT on the nVidia side, the x1600 on the ATi side) do not require bridges even when linked.

the x1600 did not need a bridge because it used the older Crossfire not the newer CrossfireX which does require a bridge. Just like SLi.

The bridge allows the 2 cards to communicate, the only time where a bridge is not needed, is in Hybrid SLi/CrossfireX

Nate, that should work without any problems. I just think this board can't run dual pci-e video cards (not referring to SLI). Some of the manufacturers specifically state on their website whether or not dual video cards are supported.

Good luck

I'm planning on trying that pretty soon here. Gonna go watch a movie with my wife.

Th|nk3r, some boards do not support dual cards, but these specifically do. As i've come to find out all Ultra-D boards are in fact Ultra DxG (dual express graphics) boards. Both of mine say it and so does Nate's.
I suppose if worse comes to worse I'll just pull the board out of my sig rig and use that since I only need one functioning slot.

And one more thing, I went out and bought a soldering iron to SLi mod the board (after I verify that the lower slot does in fact work).

. I'll be sure to take pics and post screen shots when I'm done.

BO, since your folding on that board I would back up the bios and flash to the latest and see if that does the trick. It may be a bug that was addressed. Check out the bios update faq and see if it's in there.

BlackOmega, thanks for clarifying. Yeah I just wasn't sure. I mean obviously multiple video cards would work ie. PCI slots but with PCI-E...I was unsure.

Hope the soldering gun works out for this mod.

Good luck

Hey BO, I would try the temporary pencil mod first just to make sure every thing is a ok before you try the soldering iron. This way if it don't work then you wond always be wondering if you fried the sli feature of the chip set ... $0.02

I will do that as a last resort. I do definitely want to keep this BIOS because it has the SLI setting in it. I think DFI removed it on their later revisions due to flak from Nvidia.
However, the only thing on DFI's site is an auto BIOS installer kind of like Asus update.

Well I've verified that both cards and both PCIe slots work individually. SO either I am missing a setting somewhere in the BIOS or when 2 cards are inserted the lower slot gets deactivated.

I suppose you're right. I'm just getting sick of messing with this thing.

Ok I'll do the no.2 pencil thing first then, if everything goes well I'll make it "permanent".

BlackOmega · 06-13-09

SO I tried the pencil mod, and well I'm not sure if it worked or not since it still doesn't pick up the 2nd GPU. How ever I did notice that there was resistance with the no2 pencil mod.

Kryton · 06-13-09

Let me do some research - I believe I know someone who's done this mod successfully.

I'll get back with you as soon as I find out something or maybe a "How To" link.

Thlnk3r, I finally got around to doing testing just for you, as promised a while ago. Results are in my build thread.
