10. JP29 Memory Voltage Jumper
This motherboard supports all DDR200/266/333 DDR SDRAM on market, therefore you
don't need to adjust this JP29 memory voltage jumper from its default setting. However, if
you wish to use DDR400 SDRAM which requires higher voltage on this motherboard, you
may have to adjust the jumper to pin1-2 for a higher voltage supply up to 2.7V.

If the housing has been designed with an audio port on the front panel, you'll be able to
connect onboard audio to front panel through this connector. By the way, please remove the
jumper cap from the Front Audio Connector before you connect the cable. Do not remove
this yellow jumper cap if your housing doesn't have an audio port on the front panel.

somewhere on the chassis. So, whenever the sensor is triggered by lights or by the opening of
the chassis, the system will beep to inform you. Please be informed that this useful function
only applies to advanced chassis, you may purchase an extra sensor, attach it on your chassis,
and make a good use of this function.
