Feature Summary

(Note 1) Due to standard PC architecture, a certain amount of memory is reserved for system usage and

therefore the actual memory size is less than the stated amount.
For example, 4GB of memory size will instead be shown as 3.xxGB memory during system
startup.

(Note 2) To set up an 8 channel audio configuration, you must use Audio Combo Kit (optional device).
