| PCI Express 2.0 x16 | 2 x PCI Express x16 slots, running at x16 (PCIEX16_1 and PCIEX16_2)* 1 x PCI Express x16 slot, running at x8 (PCIEX8)**
* For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16_1 slot; if you are installing two PCI Express graphics cards, it is recommended that you install them in the PCIEX16_1 and PCIEX16_2 slots.
**The PCIEX8 slot shares bandwidth with the PCIEX16_2 slot. When PCIEX8 is populated with a PCI Express graphics card, the PCIEX16_2 slot will operate at up to x8 mode. |
