(The item name may differ depending on your operating system.)

• Please note the HDMI audio output only supports AC3, DTS and 2-channel-LPCM formats.

(AC3 and DTS require the use of an external decoder for decoding.)

• When removing the cable connected to a back panel connector, rst remove the cable from your

device and then remove it from the motherboard.

• When removing the cable, pull it straight out from the connector. Do not rock it side to side to prevent

an electrical short inside the cable connector.

(Note 2) Simultaneous output for DVI-D and HDMI is not supported.

Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.

1. Dual Channel mode cannot be enabled if only one memory module is installed.

2. When enabling Dual Channel mode with two or four memory modules, it is recommended that memory

of the same capacity, brand, speed, and chips be used and installed in the same colored sockets for

optimum performance.
