Power management and temperature control
ACPI technology
Matrox 4Sight EV6 is compliant with advanced configuration and power
interface (ACPI) technology. This technology monitors how the UEFI, operating
system, and peripheral devices communicate with each other about power usage.
ACPI allows the Matrox 4Sight EV6 unit to conserve energy by transitioning
unused devices into lower power states. ACPI components gather information
about power consumption from the unit and pass this information onto the
operating system. The operating system then manages power to the unit’s different
components on an as-needed basis.
The ACPI features implemented in the Matrox 4Sight EV6 unit include:
• The ability for the unit to perform a complete shut-down, in which it will be
powered off automatically.
• Support for an S4 sleeping state, for which the operating system can be enabled
or disabled to automatically wake the unit from hibernation mode.
• Support for processor power management.
• Support for temperature management using passive cooling techniques.
Enhanced Intel
SpeedStep
technology
The Intel Core i5 processor uses Enhanced Intel SpeedStep technology (EIST) to
enable very high performance, while also meeting the power-conservation needs
of the Matrox 4Sight EV6 unit. The operating system dynamically adjusts
processor voltage and core frequency (CPU speed) based on the CPU’s demand
for processing power. This results in decreased average power consumption and
decreased average heat production.
