AMD and FirePro are trademarks of Advanced Micro Devices, Inc.

Not all features are available in all editions or versions of Windows. Systems may require upgraded and/or separately purchased hardware, drivers and/or software to take full advantage of Windows functionality. See http://www.microsoft.com External link .

NVIDIA, NIVDIA QUADRO and NVIDIA Kepler are trademarks or registered trademarks of NVIDIA Corporation in the U.S. or other countries.

*This system may require upgraded and/or separately purchased hardware and/or a DVD drive to install the Windows 7 software and take full advantage of Windows 7 functionality. See microsoft.com/windows/windows-7/ External link for details.

**Supported only in the Z420 600W power supply chassis.

***Each drive requires a PCIe x4 (minimum) slot to be available. Full performance is obtained only when using PCIe slots connected to the CPU. Non-CPU PCIe slots may see a decrease of up to 10%. Please see slot configuration recommendations at http://www8.hp.com/us/en/campaigns/workstations/z-turbo-drive.html. Note that graphics cards, Thunderbolt, and other devices will require PCIe slots.

  1. Multi-Core technologies are designed to improve performance of multithreaded software products and hardware-aware multitasking operating systems and may require appropriate operating system software for full benefits; Not all customers or software applications will necessarily benefit from use of these technologies.
  2. 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. See intel.com/info/em64t External link for more information.
  3. Intel's numbering is not a measurement of higher performance.
  4. Although the Intel Xeon E5-2600 processor family supports dual processors, the HP Z420 Workstation does not support dual processor configurations.
  5. The specifications shown in this in this column represent the following: (all core maximum turbo steps, one core maximum turbo steps). Turbo boost stepping occurs in 100MHz increments. Processors that do not have turbo functionality are denoted as N/A. 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. Please visit intel.com/technology/turboboost External link for more information. NOTE: Although the Intel® Xeon® Processor E5-2600 family supports dual processors, the HP Z420 Workstation does not support dual configurations.
  6. Each processor supports up to 4 channels of DDR3 memory. To realize full performance at least 1 DIMM must be inserted into each channel. 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.
  7. SATA hardware RAID is not supported on Linux systems. The Linux kernel, with built-in software RAID, provides excellent functionality and performance. It is a good alternative to hardware-based RAID. Please visit h20000.www2.hp.com/bc/docs/support/SupportManual/c00060684/c00060684.pdf for RAID capabilities with Linux.
  8. For hard drives, 1 GB = 1 billion bytes. TB = 1 trillion bytes. Actual formatted capacity is less.
  9. Actual speeds may vary. Does not permit copying of commercially available DVD movies or other copyright protected materials. Intended for creation and storage of your original material and other lawful uses. Note that DVD-RAM cannot read or write to 2.6 GB Single Sided/5.2 GB Double Sided – Version 1.0 media.
  10. As Blu-ray contains new technologies, certain disc, digital connection, compatibility and/or performance issues may arise, and do not constitute defects in the product. Flawless playback on all systems is not guaranteed. In order for some Blu-ray titles to play, they may require a DVI or HDMI digital connection and your display may require HDCP support. HD DVD movies cannot be played on this workstation.
  11. HP Care Pack Services extend service contracts beyond the standard warranties. Service starts from date of hardware purchase. To choose the right level of service for your HP product, use the HP Care Pack Services Lookup Tool at http://h20560.www2.hp.com/portal/site/cpc?ac.admitted=1392942166445.2043657423.1959898185 Additional HP Care Pack Services information by product is available at http://www8.hp.com/us/en/business-services/it-services.html?compURI=1077422. Service levels and response times for HP Care Packs may vary depending on your geographic location.
  12. Thunderbolt is an optional feature available as an add-in card. Install all the latest drivers for your Thunderbolt device before connecting to the Thunderbolt port. Thunderbolt cable and Thunderbolt device (sold separately) must be compatible with Windows. To determine whether your device is Thunderbolt Certified for Windows, see https://thunderbolttechnology.net/products External link .
