Multi-Core is designed to improve performance of certain software products. Not all customers or software applications will necessarily benefit from use of this technology. 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. Some functionality of this technology, such as Intel Active management technology and Intel Virtualization technology, requires additional third-party software in order to run. Availability of future “virtual appliances” applications for Intel vPro technology is dependent on third-party software providers. Microsoft Windows® required.

PCMark05 performance benchmark and comparison testing performed on a similarly configured HP Compaq 8000 Elite SFF and HP Compaq 8200 Elite SFF. Performance profiles: PCMark05 done with the “as shipped” defaults. Actual results may vary based on system configuration and performance will vary over time depending on software installed. Power benchmark and comparison testing performed on a similarly configured HP Compaq dc7900 SFF and HP Compaq 8200 Elite SFF. Power profiles: power measurements were done with the “as shipped” defaults. Power measurements for idle, off and sleep/standby were conducted per ENERGY STAR guidelines. Actual results may vary based on system configuration and performance will vary over time depending on software installed.

Virtual Room plan will expire in 365 days after activation. Internet access required. Annual or month-to-month plans are available for purchase at www.hp.com/go/connectsolutions. Retain the serial number as lost serial numbers cannot be retrieved by HP.

Service levels and response times for HP Care Packs may vary depending on geographic location. Restrictions and limitations apply. Service starts at date of hardware purchase. Details are available at www.hp.com/go/carepack.

Available in North America only.

Intel Turbo Boost technology requires a PC with a processor with Intel Turbo Boost capability. Intel Turbo Boost performance varies depending on hardware, software and overall system configuration. More information is available at www.intel.com/technology/turboboost.

Intel Hyper-Threading Technology (HT) is designed to improve performance of multithreaded software products and requires a computer system with a processor supporting HT and an HT-enabled chipset, BIOS and OS. Contact software provider to determine compatibility. Not all customers or software applications will benefit from the use of HT. More information is available at www.intel.com/info/hyperthreading.

HP ProtectTools requires Microsoft Windows.

Maximum memory capacities assume Windows 64-bit operating systems or Linux. With Windows 32-bit operating systems, memory above 3 GB may not all be available due to system resource requirements.

HP Power Assistant may not be available in all regions. Use of this application is not required. Results will vary based on variables, which include information provided by the user, time PC is in different power states (on, standby, hibernate, off), time PC is on battery or AC, hardware configuration, variable electricity rates and utilities provider. HP advises customers to use information reported by HP Power Assistant for reference only and to validate impact in their environment. Environmental calculations were based on U.S. EPA eGrid 2007 data found at www.epa.gov/egrid/ . Regional results will vary. Requires Microsoft Windows.
