Setting up Quad SLI using a set of GX2’s is very easy, just place both cards in the motherboard, turn on, install the latest driver and reboot. Following this the four GPUs are shown in device manager and a Quad SLI option appears in the Nvidia control panel. Obviously there is a hardware requirement for two 8pin PCIe and two six pin PCIe connectors but providing you have them on an 850w+ PSU the system should be ready to go.
As we noted in our original GX2 article there are various light up sections on the GX2’s which help show the status of each card. Shown below are the illuminations in action. Beside the DVI ports we have two LED’s, the green signifies normal operation with blue identifying the primary card in an SLI setup. At the back of the card are the power sockets which light up green when connected correctly and red when not.
Configuring the 3-way SLI setup was near identical to Quad SLI with only the option available in the control panel appearing slightly different. Again, just click the option for SLI and hit apply to enable the technology. For those interested, the power requirement for a 3-way setup is 1100w with six 6pin PCIe power connectors available.
