Intel® Turbo Boost Technology—maximum single-core turbo frequency (GHz). Intel
Turbo Boost Technology requires a PC with a processor with Intel Turbo Boost
Technology capability. Intel Turbo Boost Technology performance varies depend-
ing on hardware, software, and overall system conguration. Check with your PC
manufacturer on whether your system delivers Intel Turbo Boost Technology. See
www.intel.com/technology/turboboost for more information.
2
Intel® Hyper-Threading Technology requires a computer system with a processor
supporting HT Technology and an HT Technologyenabled chipset, BIOS, and oper-
ating system. Performance will vary depending on the specic hardware and
software you use. See www.intel.com/info/hyperthreading for more information.
3
Intel does not warrant against use of its processors and desktop boards outside
of specication. Intel recommends users to ensure sufcient airow and cooling
of the system when enabling the processor and memory frequency tuning feature.
4
System resources and hardware (such as PCI and PCI Express*) require physical
memory address locations that can reduce available addressable system memory.
This could result in a reduction of as much as 1 GB or more of physical addressable
memory being available to the operating system and applications, depending on
the system conguration and operating system.
5
Intel® High Denition Audio requires a system with an appropriate Intel® chipset
and a motherboard with an appropriate codec and the necessary drivers installed.
System sound quality will vary depending on actual implementation, controller,
codec, drivers, and speakers. For more information about Intel® HD Audio, refer to
www.intel.com/design/chipsets/hdaudio.htm
6
The Intel® Core Utilities Bundle includes Intel® Integrator Assistant, Intel® Integrator
Toolkit, Intel® Express Installer, and Intel® Express BIOS Update.
7
64-bit computing on Intel® architecture requires a computer system with a proces-
sor, 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 congurations. See http://developer.intel.com/
technology/intel64/index.htm for more information.

Responsive performance measurements performed using Intel Core Processor,
Intel Z68 Express Chipset, Intel® Solid-State Drive, and Intel® Rapid Storage Tech-
nology driver. Performance as measured by PCMark Vantage v1.0.1 tests on sys-
tems with Intel DZ68PL motherboard, Intel Core processor, Intel 6 Series chipset,
Microsoft Windows* 7 Ultimate 64-bit, SATA 2 for both SSD and HDD, Hitachi 7200
RPM 320 GB HDD, Intel 20/40/80 GB Solid-State Drives, Integrated Graphics,
4 GB 1066 MHz DDR3 DRAM. System performance improvement on platforms
is conguration-dependent; as measured by PCMark* Vantage.
