5 Special Features
5.1 S5 Eco
Kontron‘s new high-efficient power-off state S5 Eco enables lowest power-consumption in soft-off state – less than 1
mA compared to the regular S5 state this means a reduction by at least factor 200!
In the "normal" S5 mode the board is supplied by 5V_Stb and needs usually up to 300mA just to stay off. This mode
allows to be switched on by power button, RTC event and WakeOnLan, even when it is not necessary. The new S5 Eco
mode reduces the current tremendously.
The S5 Eco Mode can be enabled in BIOS Setup
Following prerequesites and consequences occur when S5 Eco Mode is enabled
» The power button must be pressed at least for 200ms to switch on.
» Wake via Powerbutton only.
» "Power On After Power Fail": only "stay off" is possible
» In 12V only mode the S5 Eco Mode must be switched off to enable the board to start immediatelly
5.2 Hyper Threading
Hyper Threading (officially termed Hyper Threading Technology or HTT) is an Intel®-proprietary technology used to
improve parallelization of computations performed on PC´s. Hyper-Threading works by duplicating certain sections of
the processor—those that store the architectural state but not duplicating the main execution resources. This allows a
Hyper-Threading equipped processor to pretend to be two "logical" processors to the host operating system, allowing
the operating system to schedule two threads or processes simultaneously. HTT support always relies on the Operating
System.
Note: HTT is only supported on the Z530 (1.6 GHz) version of the COMe-cSP2. Operating system images from the
1.1GHz (Z510) and 1.6GHz (Z530) module may not be fully compatible. It‘s recommended to use separate
images on hyperthreading and non-hyperthreading variant.
