Hysteresis
Higher numbers increase the time required to persist in state when crossing
thresholds before switching. Set to 0 for fastest reaction and increase this to require
longer times to remain said state before activation.
Configuration options: [Auto] [0] - [255]
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. You can also select various Memory Presets to load
settings suitably tuned for some memory modules.
Changing the values in this menu may cause the system to become unstable! If this
happens, revert to the default settings.
