GeForce 7950 GX2 on pci-e 1.0 socket

post #1 of 9
Thread Starter 
Hi all


I have a Dell computer with an Intel D915GAV motherboard.... I'm trying to mount my GeForce 7950 GX2 gfx card but it won't recognice it in the BIOS.

The D915GAV only has PCI-E 1.0 and the gfx card is PCI-E 2.0..... I have read several places on the internet that it shouldn't be a problem.... it should only slow it down......

I only get a black screen... And when I use the on-board VGA I can't see it in the BIOS...


Any Ideas why on how to get it to work??


Regards
Jonas

did you plug in the power cords to the Graphics card?

if it is a pre built Dell computer, the PSU will probably be bad and even not have any plugs for a graphics card that did not come with the PC

The 7950 GX2 shouldnt be 1.0, shouldn't it..? You sure the monitor is plugged into the graphics card and not the inboard video?

If it is a PCI-E 2.0 card, then it is compatible with PCI-E 1.0

@pangeltveit:
I replaced the standard PSU with a 750 Watts.... so that shouldn't be a problem. I also attached the powerconnector to the gfx card.....

@kaivorth:
Monitor is plugged into the gfx card..... result=black screen. When I then moves the cable to the onboard VGA, then I get a picture.... so it still runs on the onboard .

Try disabling the onboard video all together in the BIOS. If that doesn't work either, try to run the card in a different setup to see if it's maybe a problem with the card..

In bios, change the video output from Onboard to PCI-Express or Expansion Card. Dell's will usually have the PCI-E option.
There will be no compatibility issues using that card in your system.

Sounds like your card might be dead. Do you have another card you could throw in to try? The GeForce 7 series are all PCIe 1.0, 16x cards. But any PCIe card will work in any PCIe slot. You could hypothetically throw a GTX590 into that Dell and it should theoretically work (would likely be bottlenecked by the CPU, but thats not the point).
