Intel® Virtualization Technology requires a computer system with an enabled Intel® processor, BIOS, virtual machine monitor (VMM) and, for some uses,
certain platform software enabled for it. Functionality, performance or other benefits will vary depending on hardware and software configurations
and may require a BIOS update. Software applications may not be compatible with all operating systems. Please check with your application vendor.
3
64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications
enabled for Intel® 64 architecture. Processors will not operate (including 32-bit operation) without an Intel 64 architecture-enabled BIOS. Performance
will vary depending on your hardware and software configurations. Consult with your system vendor for more information.
4
Enabling Execute Disable Bit functionality requires a PC with a processor with Execute Disable Bit capability and a supporting operating system.
Check with your PC manufacturer on whether your system delivers Execute Disable Bit functionality.
5
The acoustic benefits of the 4-pin header are reliant on a properly designed motherboard. Contact your board manufacturer for compatibility.

Intel® 975X, P965, X38, and P35 Express Chipsets support Intel® Core™2 Quad processors. Other 3rd party chipsets may support Intel Core 2 Quad
processors. Contact your board manufacturer for compatibility.

Features and Benefits of the Intel® Core™2 Quad Processor
Features
Benefits
Quad-Core Processor
Provides four complete execution cores in a single processor with up to 12 MB of L2 cache and up to a
1333 MHz Front Side Bus. Four dedicated, physical threads help operating systems and applications deliver
additional performance, so end users can experience better multi-tasking and multi-threaded performance
across many types of applications and work loads.
Intel® Wide Dynamic
Improves execution speed and efficiency, delivering more instructions per clock cycle. Each of the four
Execution
cores can complete up to four full instructions simultaneously.
Intel® Smart Memory Access
Optimizes the use of the data bandwidth from the memory subsystem to accelerate out-of-order execution.
A newly designed prediction mechanism reduces the time in-flight instructions have to wait for data. New
pre-fetch algorithms move data from system memory into fast L2 cache in advance of execution. These
functions keep the pipeline full, improving instruction throughput and performance. 45nm versions further
improve this feature, with more efficient methods of loading and storing data in main memory.
Intel® Advanced Smart
Provides shared level 2 cache across each pair of cores that can be dynamically allocated to each processor
Cache
1
core, within the pair, based on workload. This efficient implementation increases the probability that each
core within the pair can access data from fast L2 cache, significantly reducing latency to frequently used
data and improving performance.
Intel® Advanced Digital
Accelerates the execution of Streaming SIMD Extension (SSE) instructions to significantly improve the
Media Boost
performance on a broad range of applications, including video, audio, and image processing, and multimedia,
encryption, financial, engineering, and scientific applications. The 128-bit SSE instructions are now issued
at a throughput rate of one per clock cycle effectively doubling their speed of execution on a per clock
basis over previous generation processors. 45nm versions include a new Super Shuffle Engine, which
improves existing SSE instructions while enabling significant gains on the latest SSE4 instruction set.
SSE4-optimized applications, such as video editing and encoding in high-definition resolution, will see
additional performance improvements.
Intel® Virtualization
Allows one hardware platform to function as multiple “virtual” platforms. Intel® VT improves manageability,

limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions.
Intel® 64

Architecture
Allows the processor to access larger amounts of memory. With appropriate 64-bit hardware and software,
platforms based on an Intel processor supporting Intel® 64 architecture can allow the use of extended
virtual and physical memory.
Execute Disable Bit
4
Provides extended virus defense when deployed with a supported operating system. Memory can be marked
as executable or non-executable, allowing the processor to raise an error to the operating system if malicious
code attempts to run in non-executable memory. This can prevent the code from infecting the system.
Digital Thermal Sensor (DTS)
Provides for more efficient processor and platform thermal control improving system acoustics. The DTS
continuously measures the temperature at each processing core. The ability to continuously measure and
detect variations in processor temperature enables system fans to spin only as fast as needed to cool the
system. The combination of these technologies can result in significantly lower noise emissions from the PC.
Intel Designed Thermal
Includes a 4-pin connector for fan speed control to help minimize the acoustic noise levels generated from

Multi-tasking environments can be expanded like never before.
Users can stream high-definition content while playing a high-
framerate game, or run multiple complex data bases while
developing professional content and running virus protection
software in the background. The Intel Core 2 Quad processor
is a powerful new tool for today, with the ability to grow and
expand tomorrow.
