1. The Intel® Visual BIOS may not be available at time of launch of DZ77BH-55K
product and may require a BIOS update.
2. Warning: Altering clock frequency and/or voltage may (i) reduce system stability
and useful life of the system and processor; (ii) cause the processor and other
system components to fail; (iii) cause reductions in system performance; (iv) cause
additional damage; and (v) affect system data integrity. Intel has not tested,
and does not warranty, the operation of the processor beyond its specifications.
3. Responsive performance measurements performed using Intel Core Processor,
Intel Z68 Express Chipset, Intel® Solid-State Drive, and Intel® Rapid Storage
Technology driver. Performance as measured by PCMark Vantage v1.0.1 tests
on systems with Intel DZ68BC 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 DDR 3 DRAM. System performance improvement
on platforms is configuration-dependent; as measured by PCMark* Vantage tests.
Boot Times taken with Microsoft Velocity v4.3 and Microsoft PwrTest (included
in Microsoft WDK, for S4 times only).
4. BIOS Update may be required to support Rapid Start Technology features.
This Feature may not be available at initial launch of product.
5. Intel® Turbo Boost Technology requires a PC with a processor with Intel Turbo
Boost Technology capability. Intel Turbo Boost Technology performance varies
depending on hardware, software, and overall system configuration. Check with
your PC manufacturer on whether your system delivers Intel Turbo Boost Technology.
See www.intel.com/technology/turboboost for more information.
6. Intel® Hyper-Threading Technology requires a computer system with a procesor
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. For more information including details on which processors
support HT Technology, see www.intel.com/info/hyperthreading.
7. Maximum peak memory bandwidth requires four DDR 3 modules to be populated
in each of the blue memory slots. DDR 3 2400 memory support on this
motherboard requires advanced knowledge of BIOS and memory tuning; individual
results may vary. For specific supported memory for this motherboard, please
visit www.intel.com/products/motherboard/ for more details.
8. 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 www.intel.com/design/chipsets/hdaudio.html.
9. 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 configuration and operating system.
