Block Diagram
(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 PCIEX8 is populated with a PCI
Express graphics card, the PCIEX16 slot will operate at up to x8 mode.
(Note 2) To reach DDR3 1866 MHz or above, you must install two memory modules and install them in the DDR3_3 and
DDR3_4 memory sockets.
