Removing or Installing an Expansion Card
The computer has three standard full-height PCI expansion slots, one PCI Express x1 expansion slot,
one PCI Express x16 expansion slot, and one PCI Express x16 expansion slot that is downshifted to
a x4 slot.
NOTE:
You can install a PCI Express x1, x8, or x16 expansion card in the PCI Express x16 slots.
For dual graphics card configurations, the first (primary) card must be installed in the PCI Express
