(Note 1) Whether 1066 MHz or above memory speed is supported depends on the CPU being used.
(Note 2) Simultaneous output for DVI-D and HDMI is not supported.
(Note 3) 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.
