(Note 1) For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the
PCIEX16_1 slot. The PCIEX8_1 slot shares bandwidth with the PCIEX16_1 slot. When PCIEX8_1 is populated
with a PCI Express graphics card, the PCIEX16_1 slot will operate at up to x8 mode.
(Note 2) Simultaneous output for DVI-D and HDMI is not supported.
