(Note 1) For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install
it in the PCIEX16 slot. The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8
slot is populated, the PCIEX16 slot will operate at up to x8 mode.
(Note 2) Simultaneous output for DVI-D and HDMI is not supported.
