Front Side Bus Speed

JP12 is used to set the system (front side) bus speed for the pro- cessors. It is best to keep this jumper set to Auto. See the table on the right for jumper settings.

Spread Spectrum

J35 is used to enable or disable the Spread Spectrum feature. Spread Spectrum is a technique used to stabilize operations when a system is being affected by electromagnetic interference. The normal (default) position is open to disable Spread Spectrum. See table at right for jumper settings.

PCI 3.3V Standby Enable/ Disable (X5DL8-GG)

JP2 is used to enable or disable a 3.3V standby voltage on pin A14 of the PCI-X slots. If you have a LAN or modem add-on card in- serted into a PCI-X slot that you wish to "wake" the system up with, you should enable this jumper. Otherwise, leave this jumper on pins 1-2 (disabled). The normal (default) position is disabled. See the table on the right for jumper settings.

VGA Enable/Disable

JP56 allows you to enable or dis- able the VGA port. The default position is on pins 1 and 2 to en- able VGA. See the table on the right for jumper settings.
