DRAM Timing Control
The sub-items in this menu allow you to set the DRAM timing control features. Use the <+>
and <-> keys to adjust the value. To restore the default setting, type [auto] using the keyboard
and press the <Enter> key.
Changing the values in this menu may cause the system to become unstable! If this
happens, revert to the default settings.
