Configure advanced CPU settings

Mobile version - 13.xx_______________________

Manufacture

: Intel

Brand String

: Intel® Pentium® M processor 1.40GHz

Frequency

: 1.40GHz

FSB Speed

: 400MHz

Cache L1

: 32kB

Cached L2

: 2048kB

Execute Disable Bit – [Disabled] or [Enabled]

This feature is only appears for Celeron CPUs that support it.

If [Disabled] is selected, it forces the XD feature flag to always return to 0.

On Demand Clock Modulation – [Disabled], [25%], [50%], or [75%]

This feature uses on demand clock throttling or modulation to reduce the performance of Celeron-M CPUs and is only supported by the Celeron-M CPUs. The % value indicates the CLOCK ON to CLOCK OFF interval ratio. If 75% is selected, the CPU performance is decreased by about 25%.

Intel® SpeedStep™ Technology – [Maximum Speed], [Minimum Speed], [Automatic], or [Disabled]

This feature only appears for the Pentium CPUs that support it.

Intel® Mobile Pentium® Processors with Intel® SpeedStep™ technology let you customize high performance computing on your XTX 820 design project. Automatic allows the operating system (OS) to control CPU speed and Disabled uses the default speed of the CPU. If the OS has the control of the CPU speed, it can allow the processor to drop to a lower frequency (by changing the bus ratios) and voltage, conserving battery life while maintaining a high level of performance, when powered by a battery. This allows you to customize performance for the XTX 820 CPU.

Max. CPU Frequency – [1800 MHz], [1600 MHz], [1400 MHz], [1300 MHz], [1200 MHz], [1100 MHz], [1000 MHz], [900 MHz], [800 MHz], or [600 MHz]

This feature is only available for the Pentium CPUs and the default settings are based on the frequency of the CPU (1800 MHz or 1400 MHz).

>Chipset Configuration

Memory Hole – [Disabled] or [15MB-16MB]

IOAPIC – [Disabled] or [Enabled]

This field sets the IOAPIC function on the I/O Hub (82801FBM) used on the XTX 820.

APIC ACPI SCI IRQ – [Disabled] or [Enabled]

C4 On C3 – [Disabled] or [Enabled]

If this field is set to [Enabled], the CPU is put into C4 state when the ACPI OS initiates a transition to C3 state. This results in an additional power savings when in desktop idle mode.
