Meaning
This item allows your unit to enter hibernation at the request of the operating system (also
known as sleep state S4, or suspend to disk). In hibernation, all contents of a specific
region of memory are saved to a mass storage device and the Matrox Supersight
SHB-5520 board is powered off.
This item allows you to select the highest ACPI sleep state that is used when your unit
enters a sleep state, if you have not enabled hibernation (see item above).
When set to Suspend Disabled, no sleep states are available for suspend mode.
When set to S1 (CPU Stop Clock), all processor caches are flushed, and the CPU stops
executing instructions. Power to the CPU and RAM is maintained; some devices are
powered down.
When set to S3 (Suspend to RAM), power to RAM is maintained; the CPU and most other
devices are powered down. It takes more time to return from the S3 state than the S1
state.
Note that when power management options are enabled, connecting the keyboard and/or
❖
the mouse through a USB hub causes your operating system to reboot when resuming
from stand-by or hibernation. Therefore, if you are using USB devices that can force the
platform to resume (from a given power state to the S0 power state), do not connect
them through a USB hub. Otherwise, disable hibernation and suspend all power saving
options.
CPU Configuration submenu
The CPU Configuration submenu allows you to set all CPU configuration
settings.
Meaning
This item reports the name of the processors installed on the Matrox Supersight SHB-5520 board.
This item reports whether the CPUs support the Intel EMT64 architecture or not.
This item allows you to enable hyper-threading for the operating system. Hyper-threading allows a processor
core to execute two separate software streams (threads) at the same time. One Intel Xeon Quad-Core
processor can, therefore, run up to eight threads simultaneously.
Set this item to Enabled if your system is optimized for hyper-threading.
This item allows you to select the number of processor cores available to your operating system and/or
processing applications.
When set to All, all processor cores of the CPU are enabled. Since there are two CPU chips per Matrox
Supersight SHB-5520 board, a total of eight processor cores would be active on the board.
Note that the default setting of this value is optimized for the Matrox Supersight SHB-5520 board.
