6. SLI/CFX switch (SLI/CFX)
This switch allows you to determine the slots for 2-WAY or 3-WAY graphics card
installation. When enabled, the PCIE LEDs near the slots light up, telling you to install
the graphics cards to the specic slots.
• We recommend that you insert your graphics cards into PCIEX16_1 and PCIEX16_5
when 2-WAY SLI/Crossre is enabled.
• We recommend that you insert your graphics cards into PCIEX16_1, PCIEX16_3, and
PCIEX16_5 when 3-WAY SLI/Crossre is enabled.
• The LEDs below the SLI/CFX switch and near the PCIE slots light up when the SLI/
CFX switch is enabled. Refer to section 1.2.8 Onboard LEDs for the exact location of
the SLI/CFX and PCIE LEDs.
• After adjusting PCIE bandwidth in the BIOS, shut down the system for the PCIE LEDs
to update the lighting effect.
