Two Graphics Card Problem!

[jsbond007]

Guys,

 

I am having problems with my second graphics card. I have three monitors hoked up for multi tasking ( CAD programmes ). My computer recognises the first two monitors on my graphics card but fails to recognise the third on the second card.

 

When i enter bios, i see NC,NC,8x,1x. I have double checked to see all the jumpers are in sli mode. Also when i go into system, i can only see when 6200 graphics card under divice manager and display adapter.

 

However, when i go under monitors in device manager, i can see all three of my monitors.

 

I have tried re-installing the drivers but still the same thing.

 

Can someone please help me?

 

Many thanks.

 

James.

bumping this for anyone that might know

 

i'd test, but i dont have that many monitors i can move around to hook up 3 at once =(

Hi james

 

I see u have an Ultra. Is that right?

If u have an ultra and put jumpers to SLI then your computer (nvidia or bios i dont know which) cannot recognize the second card. Put back jumpers to normal position and u r good to go but with reduced bandwidth (unfortunately) for the second card at 2X.

There is a solution but u have to mod the chipset to SLI.

For more info later , when i finished my dual card (nvidia-ATI)project on my SLI board

Also take a look at this link

and make a search on the same site for SLI, have some good info.

Thanks mate, you were right. At least it works, even on reduced bandwidth. However, i am sure that the ultra motherboard should work as two 8x pci express slots. That is why they call it Dual Xpress Graphics. I was under the impression this is what separated the ultra from the sli mode. I was interested in operating two graphics card but not in sli mode.

 

Is anyone else in this forum using two graphics card on the ultra board. I would be very much interested to know there config.

 

Travis/Rgone, do you think you can confirm from DFI if two cards can indeed run on x8 mode.

 

Many thanks again.

Also, just another quick point, why do ultra-d motherboards of sli jumpers if there is no use of using them.

I have just finished reading a neoseeker review. If you see page 2 at the bottom, it says that the jumpers can be re-configured to sli mode to give you two 8x pci express lanes. Hardcoreware.net ( page 1 ) says the same thing. I quote : "8 lanes to the first graphics slot, 8 lanes to the second graphics slot, 4 lanes to the x4 slot, and disabling the x1 slot. This would be the preferred config for dual video card usage."

Well in your case it wont matter. Those 6200s arn't filling the PCI-e anyway if Im correct so I dont think U will have any performance hit whichever way.

Have you tried some of the older vid drivers? I'm wondering if you are being inhibited by NVIDIA through drivers. My reference for this idea comes from here:

 

anandtech's review

 

Not completely sure if it really applies to exactly what you're attempting to do :cool:

All reviews taking about the SLI mod Ultra.

If u mod ur chip, may have the 8X mode to both of the cards.

 

I asked these questions to DFI support before buy the board, cause i need to do exactly what u want to do.

I like to have a 2-3 monitor configuration but hell i m not gonna buy a $$$ second card to run it at 2X!!

Their answer was that with Ultra u have to run it 16X-2X.

Obviously nVidia has blame them not to allow 8X-8X cause that was a "semi" SLI configuration. That is, lets say, OK in order to prevent ppl to run dual 8X "semi SLI"on Ultra boards, but the question is what happen when u have 2 "not SLI" cards like yours?? Or an nvidia and ATI card?

Why not to allow users to use the dual 8X videos with "non SLI" cards?

I think DFI (bios) and nVidia (chipset-drivers) do their best to prevent that.

 

If u want to use the dual 8X u have to mod the chip to SLI. I think its pretty easy and u can find some info and pics to anandtech.

 

Another question to all SLI users out their is what happen when they run their cards without SLI bridge?

 

1. Do they have problem to run them like that?

2. Do they have shared bandwidth (8X-8X) and performance without issues?
