Does the moving of my graphics card to the lower pci-e slot make it run any slower. I have moved all 6 jumpers a notch down too?
 
I seen on the theread about the Ultra-D/Sli DFI boards that the top Pci-e hole is faster and that the yellow Ram holes are better than the orange ones.

I have no experience with the jumper config but if all down makes the lower PCIe slot a 16x slot and the top one a 1x it should make no difference.

really? do you have a link to the thread because i was told that both sli slots are the same speed when u change the jumpers and the orange slots are faster than the yellow (or at least should be used over them)

Classic :D:p

As far as i know moving the jumpers splits the slots to 8x and 8x? There is a hardmod available to turn the Ultra-D into an SLI-D, might try this myself soon...

ill stick with the pink ones thanks suman ;)

Ive moved it back to the top position and it shows 16x in the setup now (no idea what it said before, i forgot to check)
 
with the jumpers on sli the slots are 8x and 8xi think as its got dual express graphics or something (no idea what its for)

on normal i assume they are 16x and 1x?

I tried moving my card to the lower slotas to try and save my chipaset from melting but it was very unstable
 
By default, the jumpers are configured to route 16 PCI Express lanes to the first x16 slot, two lanes to the second x16 slot, and one lane to each of the x4 and x1 slots. The jumpers can be switched to route eight lanes to each of the x16 slots and four lanes to the x4, effectively disabling the x1 slot. Unfortunately, that's the only way to get four lanes to the x4 slot—the board can't be configured to route 16 lanes to the primary x16 and four lanes to the x4 at the same time.

its not pci-e x1 on the Dfi ultra its 2x when running the other pci-e slot,
it only becomes 1x when its a sli board and the ultra Dis not an sli board but it can be modded to become an sli board

Dfi ultra pci e speeds
pci e 1 = 16x slot
pci e 2 = 2x slot

all nforce4 SLI boards
pci e 1 = 16x slot
pci e 2 = 1x slot
When In SLI 8x+8x

my freind has a Pci-e Lsi megaraid 320 scsi card in the Ultra D using slot 2
and this gives him 2x speed, the card would'nt even function @ 1x
thats why he went with Ultra D board Twin graphics without enabling SLI,
also he has got the card to work using SLI on an asus premium Board using it @ 8x in slot 1 or 2 he also had a geforce 6800 in other slot and noticed no slow downs by running 1 graphics card @ 8x

their is no diffrence running 1 graphics card @ 8x it still has a load of bandwith, most graphics cards are problay not even bottlenecked by 8x never mind 16x, theirs a admin on Dfi Forums who has tested this.

so running @ 2x will still power a half decent graphics card on the other pci e slot.
 
hey, has anyone got this board and if they could tell me whether a 7800GTX would fit in the top PCI-Eslot without disturbing the chipset cooler?

i cant use the 2nd PCI-E slot due to my water cooling coming through there. :confused:

My X1800XT reaches over the chipset cooler, with about a 6mm gap between the cooler and bottom of the card.

yep correct. Just make sure you screw the card in at the back otherwise it fall down about a millimetre or two, just enough to touch on the chipset fan and make it stop :(
 
The chipset cooler is lower than the height of the PCIe slot so there is no way it can interfere :confused:

My 7800GT fits just fine in the top slot.
