Chapter 7: BIOS

7-7

Execute-Disable Bit Capability (Available when supported by the OS and

the CPU)

Set to Enabled to enable the Execute Disable Bit which will allow the processor

to designate areas in the system memory where an application code can execute

and where it cannot, thus preventing a worm or a virus from ﬂ ooding illegal codes

to overwhelm the processor or damage the system during an attack. The default is

Enabled. (Refer to Intel and Microsoft Web Sites for more information.)

Simultaneous Multi-Threading (Available when supported by the CPU)

Set to Enabled to use the Simultaneous Multi-Threading Technology, which will

result in increased CPU performance. The options are Disabled and Enabled.

Active Processor Cores

Set to Enabled to use a processor's Second Core and beyond. (Please refer to

Intel's web site for more information.) The options are All, 1 and 2.

Intel® EIST Technology

EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically

adjust processor voltage and core frequency in an effort to reduce power consump-

tion and heat dissipation. Please refer to Intel’s web site for detailed information.

The options are Disable (Disable GV3) and Enable (Enable GV3).

Intel® Turbo Boost

Select Enabled to allow the processor cores to run faster than normal under special

circumstances to improve performance. The options are Disable and Enabled.

C1E Support

Select Enabled to use the feature of Enhanced Halt State. C1E signiﬁ cantly reduces

the CPU's power consumption by reducing the CPU's clock cycle and voltage during

a Halt State. The options are Disabled and Enabled.

Intel® C-State Tech

If enabled, C-State is set by the system automatically to either C2, C3 or C4 state.

The options are Disabled and Enabled.

C-State package limit setting (Available when Intel® C-State Tech is

enabled)

If set to Auto, the AMI BIOS will automatically set the limit on the C-State package

C1 Auto Demotion

When enabled, the CPU will conditionally demote C3, C6 or C7 requests to C1 based

on un-core auto-demote information. The options are Disabled and Enabled.
