Jumper Settings for 5DLX

Jumper Settings for 5DLX


5DLX provides two modes for Jumper Settings: (1) Auto Jumper Mode; (2) Manual mode.

Auto Jumper Mode
An advanced technology eliminates the necessity for the user to be bored by jumper settings on the mainboard. It is capable of detecting the CPU brand, and setting the appropriate CPU core voltage and speed according to instructions from the user through CMOS setup menu.

To enable Auto Jumper Mode, short JP6 to position (1-2).

Manual Mode
To enable Manual Mode, short JP6 to position (2-3) and follow the jumper table below for necessary jumper settings for CPU installed.
