Replacing older computers with Execute Disable Bit-enabled systems can halt worm attacks,
reducing the need for virus-related repairs. By combining Execute Disable Bit with anti-virus,
firewall, spyware removal, e-mail filtering software, and other network security measures, IT
managers can free IT resources for other initiatives.
► Core Multi-Processing
It is used to enable or disable the feature and will be displayed only if your CPU is supporting
this feature.
► PECI
PECI stands for Platform Environment Control Interface. The PECI bus, allowing access to
this data from chipset components, is a proprietary single-wire interface with a variable data
transfer speed (from 2 kbit/s to 2 Mbit/s).
From a control standpoint, the main difference between PECI and the previously used thermal
monitoring methods is that PECI reports a negative value expressing the difference between
the current temperature and the thermal throttle point (at which the CPU reduces speed or
shuts down to prevent damage due to overheating) instead of the absolute temperature. For
example, for a CPU with maximal temperature of 85 °C and a current temperature reading of
35 °C, the value reported by PECI would be -50 °C.
► EIST Function
You can select the EIST (Processor Power Management, PPM) through this item.
Enhanced Intel SpeedStep® technology (EIST) allows the system to dynamically adjust
processor voltage and core frequency, which can result in decreased average power
consumption and decreased average heat production. There are some system require-
ments must be met, including CPU, chipset, motherboard, BIOS and operation system.
