| Post subject: | Help - NVIDIA SLI option is not showing up |
I am running an ASUS P6X58 motherboard with 12G of RAM, a Thermaltake 1200 power supply. I have been running crossfire 5870s with no problem with 3 LCDs for surround. However I just bought 2 EVGA GTX480s to run in SLI to try NVIDIA surround. I have done a fresh install of Windows 7 64 bit. I install the new NVIDIA beta drivers (258.96 beta drivers). I have a SLI bridge installed - cards are in SLOT 1 and the last SLOT (it is a tight fit on this card due to the USB connectors sitting up). When I goto the NVIDIA control panel I have no option to enable SLI? It just shows physics etc. I can run three monitors no problem however since I cannot enable SLI I cannot do surround). I am pulling my hair our. I have read about realtek drivers casuing problems so I disabled the NICS in the BIOS however still no SLI option. Thanks Brad |

I actually have 2 different versions of those drivers, one labled beta and one not. The beta one is 151 mb and the other is 121 mb. It could be one is compressed but they both have the nvidia icon. I would try redownloading the driver and reinstalling. Also I think the bridge needs to be installed in the slot closest to the rear of the computer (I believe mine had two positions where it would connect). In the Nvidia Control Panel, under 3D Settings you should have a listing for Configure SLI, PhysX, Surround. Widerron |

go to your device manager and see if your machines registers both cards... if not, try flipping the order of the cards and see if anything changes.. if all else fails, clean the .96 drivers out and then install the older beta surround drivers, .69 version... these .96s are a little fussy... I think the .69s are better personally.. but ymmv. |

Hope this guy didn't end up pulling all of his hair out. Nvidia has done a really terrible job (read: none) publicizing the massive SLI/Realtek issue, but basically Windows Update installs some drivers on any motherboard with the gigabyte Realtec NIC that mess with SLI. You need to roll back these Realtek drivers to 2009 or 2008 and then reinstall your Nvidia drivers. |
