amolet Posted November 20, 2005 Posted November 20, 2005 I have just purchased a NF4 SLI Infinity MB and a EVGA 7800 GT CO video card. I have installed video card into the first PCI-E x16 slot; however, when I check the card settings in the nvidia control panel it says the bus is PCI-E 8X. Anyone know who to get it to run at 16X? I have installed the lastest bios for both the motherboard and the video card as well at the latest drivers. I am using Win XP Pro SP2. Any ideas anyone? Thanks!

Guest oRiOn Posted November 20, 2005 Posted November 20, 2005 SLI jumpers? Share this post Link to post Share on other sites More sharing options...
amolet Posted November 20, 2005 Posted November 20, 2005 There are no SLI jumpers on my board. Everything is set for the factory default. Share this post Link to post Share on other sites More sharing options...
red930 Posted November 20, 2005 Posted November 20, 2005 How do you have the BIOS setup for SLI? Share this post Link to post Share on other sites More sharing options...
amolet Posted November 20, 2005 Posted November 20, 2005 I haven't set anything in the bios for SLI. under the Pnp/PCI Config screen in the BIOS I have set Init Display first as PCIEx, the other option is PCI Slot, and Max payload size is set to 4096. I know that if I was running SLI, then the video card would be running at PCIE 8X, but since I have a single card it should be running at 16X.

Brambey Posted November 20, 2005 Posted November 20, 2005 It doesnt matter anyways, your card will run at full speed at 8x. Share this post Link to post Share on other sites More sharing options...
rvr2k3 Posted November 21, 2005 Posted November 21, 2005 I have a similar problem. My eVGA 7800GT runs at 8x speed in either slot(1 or 4) when set to SLI and only the 1x slot (4) when set for non-SLI. This card does the same thing on an eVGA board. It does not work in the x16 slot but works in the 8x slots. Share this post Link to post Share on other sites More sharing options...
Impaqt Posted November 21, 2005 Posted November 21, 2005 I'd be interested to hear if ANYONES machine reports a 16x bus. 7800 and X1800 series cards (ANd all others that I know of) are only 8x. Kinda like putting an old 4x AGP card in an 8x slot. Its an 8X slot, but only runs at 4x because the card is a 4x. Share this post Link to post Share on other sites More sharing options...
Angry_Games Posted November 21, 2005 Posted November 21, 2005 this board does not allow 16x 2x on the pci-e slots it only allows 8x 8x regardless of single or dual video cards Share this post Link to post Share on other sites More sharing options...
rvr2k3 Posted November 21, 2005 Posted November 21, 2005 My point is this card is not detected as a 16x card on the 16x slot. I assume it is the card and not the board. Share this post Link to post Share on other sites More sharing options...
notepad Posted November 21, 2005 Posted November 21, 2005 It doesnt matter anyways, your card will run at full speed at 8x. Could you or anyone else elaborate of this further? Are you saying that the 7800GTs only run at 8x anyway? Are there any video cards, or other devices that fully use the 16x slots?

I find it incredibly unlikely that these new cards come anywhere close to 8x PCi-e Share this post Link to post Share on other sites More sharing options...
