Plug the graphics card into the Primary PCI Express x16 slot on your
motherboard. This is often the slot closest to the CPU but may be the
second or third slot. Look for the slot labeled ×16. It will likely be the
only PCI Express slot with a retention lever on the end of the slot or
the one closest to the CPU.
Note: It is recommended that you install the graphics card
into the primary PCI Express x16 slot. If you install the graphics
card into the secondary slot, your system may not recognize the
graphics card and there will be nothing displayed on the monitor.
Also note that on some motherboard SbIOS, the physical
location of the primary slot can be configured when there are
more than one PCI Express x16 slots.
If you are installing an additional GeForce GTX 550 Ti graphics cards
for an SLI configuration, continue with step 6 (2-way SLI) .
Note: All of the graphics cards in an SLI configuration must
be identical.
