Intel® 9xx and 3 Series Express Chipsets support Intel® Quiet System Technology. Contact your board manufacturer for compatibility.
2
Intel® 9xx Express Chipsets have not been validated to support 1333 MHz Front Side Bus. Other third party chipsets may support Intel® Core™2 Duo processors. Contact your board manufacturer for compatibility.
3
Intel® Core™2 Duo processors support a 1333 MHz, 1066 MHz, or 800 MHz system bus. For information on a specific processor, see the Processor Spec Finder at processorfinder.intel.com or contact your Intel representative
for more information.

Intel® Virtualization Technology (Intel® VT), Intel® Trusted Execution Technology (Intel® TXT), and Intel® 64 architecture require a computer system with a processor, chipset, BIOS, enabling software and/or operating system, device
drivers, and applications designed for these features. Performance will vary depending on your configuration. Contact your vendor for more information.
5
Not all specified units of this processor support Intel® VT or Intel® TXT. See the Processor Spec Finder at http://processorfinder.intel.com or contact your Intel representative for more information.
6
Enabling Execute Disable Bit functionality requires a computer system with a processor with Execute Disable Bit capability and a supporting operating system. Check with your vendor on whether your system delivers Execute
Disable Bit functionality.
7
The acoustic benefits of the 4-pin header are reliant on a properly designed motherboard. Contact your board manufacturer for compatibility.

Features and Benefits of the Intel® Core™2 Duo Desktop Processor
Feature
Benefit
Dual-Core Processing
Two independent processor cores in one physical package run at the same frequency, and share up to 6 MB of
L2 cache as well as up to a 1333 MHz

Front Side Bus, for truly parallel computing.
Intel® Wide Dynamic Execution
Improves execution speed and efficiency, delivering more instructions per clock cycle. Each core can complete
up to four full instructions simultaneously.
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 Cache
The shared L2 cache is dynamically allocated to each processor core based on workload. This efficient, dual-
core optimized implementation increases the probability that each core 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
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 Technology
(Intel® VT)
4/5
Intel® VT allows one hardware platform to function as multiple “virtual” platforms. For businesses, Intel VT
offers improved manageability, limiting downtime and maintaining worker productivity by isolating computing
activities into separate partitions.

Intel® Trusted Execution
Technology (Intel® TXT)
4/5
Intel® TXT provides hardware-based mechanisms to help protect against software-based attacks and help protect
the confidentiality and integrity of data stored or created on the system. It does this by enabling a trusted
environment where applications can run within their own space, protected from all other software on the system.

Intel® 64
4
Architecture
Enables the processor to access larger amounts of memory. With appropriate 64-bit supporting 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
6
Provides enhanced virus protection when deployed with a supported operating system. The Execute Disable
Bit allows memory to 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, thereby preventing the
code from infecting the system.

Intel Designed Thermal Solution
for Boxed Processors
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.

Fan speed control technology is based on actual
CPU temperature and power usage.
Better Acoustics
Intel® Core™2 Duo processors are equipped with a Digital
Thermal Sensor (DTS) that enables efficient processor and
platform thermal control. Thermal sensors located within
the processor measure the maximum temperature on the
die at any given time. Intel® Quiet System Technology,
included in the Intel® Express Chipset families

, uses the
DTS to regulate the system and processor fan speeds.
The acoustic benefit of temperature monitoring is that
system fans spin only as fast as needed to cool the
system, and slower spinning fans generate less noise.
