Meaning
This item allows you to set the thermal constant TC2 for the ACPI Passive Cooling (CPU Throttle On)
formula.
This item allows you to set how often the operating system will read the temperature when Passive
Cooling is on, in tenths of a second. Passive cooling is activated when the unit's temperature increases
to the temperature set with Throttle On Temperature.
This item allows you to affect DIMM temperature-based memory throttling. DIMM memory must
support thermal sensors. When DIMM temperature-based memory throttling occurs, the memory
bandwidth (the number of transactions) is reduced. This, in turn, gives the DIMM a chance to cool
down.
This item allows you to set the memory bandwidth limit (number of transactions) when performing
DIMM temperature-based memory throttling.
This item only appears when Memory Throttling is set to Enabled.
This item allows you to set the temperature, in Celsius, at which DIMM temperature-based memory
throttling will start.
This item only appears when Memory Throttling is set to Enabled.
CPU Thermal Configuration sub-submenu
The CPU Thermal Configuration sub-submenu allows you to enable or disable
clock throttling.
Meaning
This item allows you to enable or disable the Advanced Configuration and Power Interface (ACPI) 3.0 t-states
(clock throttle states).
This item should be set to Disabled (default).
