MysteryMachine Posted December 22, 2007 Posted December 22, 2007 I just got a DFI LANParty nF4 SLI-DR to replace my dead gigabyte board. Its working great except my 8800GTS is only running in x8 mode. Is there something I am missing in BIOS or jumpers? I have it in the top slot & I have the jumpers set for non-SLI. Any ideas? I realize it doesn't make very much difference to run in x8 vs x16 but still I'd like to know what I am doing wrong with the setup.

Sharp Posted December 23, 2007 Posted December 23, 2007 Hello, Are all six jumper blocks on pins 1-2 or 2-3? (all up or all down). Quote Share this post Link to post Share on other sites More sharing options...
MysteryMachine Posted December 27, 2007 Posted December 27, 2007 They are all on 1-2 which is label as 'Normal' on the motherboard. How I am verifying is looking in CPU-Z (or Riva tuner) and it is showing "Link Width 8x Max Supported 16x" Quote Share this post Link to post Share on other sites More sharing options...
Sharp Posted December 27, 2007 Posted December 27, 2007 With the PC off. Clear the CMOS for 10 minutes by moving the CMOS jumper to the clear position. After the 10 minutes, move the jumper back to the save position. Power the PC. Just after you see it saying veriyfying DMI... Press F8. This should bring up the windows boot menu option screen. Choose enable VGA mode. Then boot into windows. Uninstall your old drivers and restart the pc. Now when you get into windows install the drivers again. Does this do anything? Important question. Did you reinstall windows + quick format the hard drive when you changed the motherboard? If not that is probably the reason why you are having issues. Note: Once windows has been installed you must install the chipset drivers first. Quote Share this post Link to post Share on other sites More sharing options...
lucky1 Posted December 27, 2007 Posted December 27, 2007 Even if the PCI-E slot is only running x8, your video card will never use all the bandwidth. Video cards couldn't even saturate AGP 8x Quote Share this post Link to post Share on other sites More sharing options...

Note: Once windows has been installed you must install the chipset drivers first. No I did not... I figured going from one NF4-SLI board with an identical setup to another this was not needed. I am using the newest NF4 SLI chipset drivers from Nvidia (as I was doing before the new motherboard) as well as the newest video card driver from nvidia. If I really have reformat I will say "no thanks" and live with x8. Quote Share this post Link to post Share on other sites More sharing options...
AnUnknownSource Posted December 28, 2007 Posted December 28, 2007 sometimes you'll get away with not re-installing windows, but it's good practice to anyway. It could even seem ok for a while, then have you pulling your hair out later... Do a re-install and see if you're having the same issue. Saying that, there's really no issue, you'd be fine at 8x...

radodrill Posted December 28, 2007 Posted December 28, 2007 How I am verifying is looking in CPU-Z (or Riva tuner) and it is showing "Link Width 8x Max Supported 16x" IIRC the 7900GT showed the same. It's basically telling you that the slot will support 16x but the card is only operating at 8x; if the board were jumpered for SLI then the max supported would be 8x.
