With NVIDIA’s gracious new fall driver I decided I cannot go any further without SLI.
Before the driver update, enabling SLI would disable all of the video interfaces on your SLI cards spare one.Â After the update the remaining interfaces on the master SLI card have been re-enabled.Â This is great if you want to dual-screen, but I must have triple if not quad displays!
Join me in my path to SLI and get some handy tips along the way…
Starting out the test PC has two NVIDIA 8800GTS’s installed and the majority of time SLI is disabled for multi-monitor support.Â I first installed the GeForce release 180 driver.Â The majority of your SLI questions can be answered here.
Next I installed the third video card that will not be in SLI mode.Â Because it is not SLI’ed you can use any modern NVIDIA card.Â For this example we used a GeForce 7950GT.Â Don’t forget to plug in the 3rd PCI Express power cable!Â I also made sure the left and right display’s were plugged into the 3rd card(7950GT).
On first boot with the 3rd card installed all the screens went black after booting windows.Â The solution was to power cycle and during POST press F8 for safe mode options.Â If running Vista, choose the 640×480 low resolution mode and boot.Â You can now see windows and accept the driver install.Â Reboot once the card is finished detecting.
Next you want to right click on the desktop and choose Personalize and Display Settings.Â Here you can right click on the disabled monitors and click attached to bring your side monitors back into view.
Hopefully your last step is to go into the NVIDIA controll panel and enable SLI and everything will be awesome!Â If you are as unfortunate as myself the SLI option will be hidden, probibly due to how new this feature is and you will have to use the old method.Â O.K.Â Now you can party!
