Supports PCI Express GEN1 frequency of 1.25 GHz resulting in 2.5 Gb/s each
direction (250 MB/s) per lane. Maximum theoretical bandwidth on interface is 4GB/s
in each direction, simultaneously, when operating in x16 mode.
Audio Subsystem
The motherboard supports Intel High Definition Audio through a Realtek ACL887 audio
codec.
These audio connectors are used for audio devices. It is easy to differentiate between
audio effects according to the colour of audio jacks.
