(Note 1) Whether 1200 MHz memory speed is supported depends on the CPU being used.
(Note 2) 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.
