Intel
®
Hyper-Threading Technology requires a computer system with a processor supporting Intel
®
HT Technology and an Intel
®
HT Technology-
enabled chipset, BIOS and operating system. Performance will vary depending on the specific hardware and software you use. For more information
including details on which processors support Intel
®
HT Technology, see
http://www.intel.com/products/ht/hyperthreading_more.htm.
β
Intel
®
High Definition 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
http://www.intel.com/.
χ
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. Performance will vary depending on your hardware and software configurations. Consult with your system vendor for
more information.
δ
Intel
®
Virtualization Technology requires a computer system with an enabled Intel
®
processor, BIOS, virtual machine monitor (VMM) and, for some
uses, certain computer system 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.
ε
The original equipment manufacturer must provide Intel
®
Trusted Platform Module (Intel
®
TPM) functionality, which requires an Intel
®
TPM-supported
BIOS. Intel
®
TPM functionality must be initialized and may not be available in all countries.
θ
For Enhanced Intel SpeedStep
®
Technology, see the
http://processorfinder.intel.com/
or contact your Intel representative for more information.
