ASUS H87-PRO Motherboard
Slots
Contents
Unlike the Z87, the H87 chipset does not allow the bandwidth of the PCI Express 3.0 x16 slot to be shared with a second slot.
The H87-PRO comes with one PCI Express 3.0 x16 slot, one PCI Express 2.0 x16 slot (that always works at x4 speed), two PCI Express 2.0 x1 slots, and three PCI slot.
The motherboard supports CrossFireX, but not SLI technology.
