Intel Pentium 4 Processor 660 3.6GHz 775pin 2Mb FSB800 BTX BOX BX80547PG3600FT Leaflet

When running applications that demand less processor power, the Operating 

System will slow the processor clock speed down. Enabling of EIST can lead to 
power efficient systems that can run quieter and cooler

The enhancement enables the desktop processor platform to access larger amounts

of memory. With appropriate 64 bit supporting hardware and software, platforms
based on an Intel processor supporting Intel

®

EM64T can enable use of extended 

virtual and physical memory. Intel

®

EM64T provides flexibility for 32 bit now and

future software that supports 64 bit computing 

Execute Disable Bit adds an extra layer of security for safer computing. Its functionality
can prevent certain classes of malicious “buffer overflow” attacks when combined
with a supporting operating system. Execute Disable Bit allows the processor to
classify areas in memory by where application code can execute and where it cannot.
When a malicious worm attempts to insert code in the buffer, Execute Disable Bit 
can disable code execution, preventing damage or worm propagation. 

HT Technology enables one physical processor to appear and behave as two logical 
processors to the operating system.  HT Technology gives you true multitasking
capabilities by enabling two applications to run simultaneously without slowing
down the system.

Enhance Halt State  is activated when the Halt instruction is executed by the processor.
Halt is executed when the OS goes into idle mode which lowers frequency and voltage 
Dynamic Voltage Identification (Dynamic VID) to reduce power consumption.

An enhanced version of Intel

®

Thermal Monitor that lowers frequency and voltage,

Dynamic VID, to help reduce power consumption. 

Includes integrated Intel

®

High Definition Audio for theatre quality sound and

multi-streaming capability and Intel

®

Graphics Media Accelerator 900 (Intel

®

GMA900) 

for vivid colors and realistic images without the cost of a video card.

Includes a 4-pin connector for fan speed control to help minimize the acoustic noise 

levels generated from running the fan at higher speeds for thermal performance

6

The fan speed control technology is based on actual CPU temperature and power usage.

Selecting the correct chassis and verifying proper thermal management is critical for integrating a high quality boxed Pentium 4 processor-based system. For
Pentium 4 processor-based platforms in the LGA775 package a chassis based on Thermally Advantaged Chassis (TAC) version 1.1 is highly recommended to
assist in maintaining an internal chassis temperature of 38°C (or lower). See: www.intel/go/chassis

4 processor supporting HT Technology and an HT Technology enabled

chipset, BIOS and operating system. Performance will vary depending on the specific hardware and software you use. See www.intel.com/info/hyperthreading
for information

EM64T Processor will not

operate (including 32-bit operation) without an Intel EM64T-enabled BIOS. Performance will vary depending on your hardware and software
configurations. Intel

EM64T enabled OS, BIOS, device drivers and applications may not be available. Check with your vendor for more information.

Execute Disable Bit requires operating system support. See http://www.intel.com/business/bss/infrastructure/security/xdbit.htm for more information on how
to implement this feature.

925X or 915 Express Chipset (see the product

spec sheet or ask your salesperson). Performance and functionality will vary depending on (i) the specific hardware and software you use and (ii) the feature
enabling/system configuration by your system vendor. See http://www.intel.com/info/hyperthreading for information on HT Technology or consult your system
vendor for more information.
