* This system may require upgraded and/or separately purchased hardware to take full advantage of Windows 7 functionality. Not all features are available in all editions of Windows 7.
See microsoft.com/windows/windows-7/ for details.
** Not all features are available in all editions of Windows 8 and 8.1. Systems may require upgraded and/or separately purchased hardware, drivers and/or software to take full advantage of
Windows 8 and 8.1 functionality. See www.microsoft.com.
*** Each drive requires a PCIe x4 (minimum)
† This system is preinstalled with Windows 7 Pro software and also comes with a license and media for Windows 8.1 Pro software. You may only use one version of the Windows software
at a time. Switching between versions will require you to uninstall one version and install the other version. You must back up all data (les, photos, etc.) before uninstalling and installing
operating systems to avoid loss of your data.
†† Supported only in the Z420 600W power supply chassis.
1. Sold as an optional or add on feature.
2. Multi-Core is designed to improve performance of certain software products. Not all customers or software applications will necessarily benet 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 oper-
ate (including 32-bit operation) without an Intel® 64 architecture-enabled BIOS. Performance will vary depending on your hardware and software congurations.
3. Up to 86% increase in available memory bandwidth can be achieved on the Z420 over the Z400 on optimized congurations with memory distributed across all channels using 1,333 MHz
memory speed on the Z400 and 1,866 MHz memory speed on the Z420. This does not imply an 86% increase in performance.
4. 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.
5. Thunderbolt™ 2 is available via an optional add-in card. Thunderbolt is new technology. Thunderbolt cable and Thunderbolt device (sold separately) must be compatible with Windows. To
determine whether your device is Thunderbolt Certied for Windows, see thunderbolttechnology.net/products.
6. HP Remote Graphics Software requires Windows and an internet connection.
7. Support for external displays as a standard feature through integrated processor-based graphics is dependent upon the particular workstation conguration; the actual number of displays
supported will vary. An optional graphics solution will be required for the support of additional displays. Additional cables required. HD (high-denition) content required to view HD images.
8. 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 congurations.
See intel.com/info/em64t for more information.
9. Intel’s numbering is not a measurement of higher performance.
10. Although the Intel Xeon E5-2600 processor family supports dual processors, the HP Z420 Workstation does not support dual processor congurations.
11. The specications shown 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 conguration. Please visit intel.com/technology/turboboost for more information.
12. Each processor supports up to 4 channels of DDR3 memory. To realize full performance at least 1 DIMM must be inserted into each channel.
13. 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.
14. For hard drives and solid state drives, GB=1 billion bytes. TB= 1 trillion bytes. Actual formatted capacity is less. Up to 36 GB is reserved for system recovery software.
15. 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.
16. As Blu-ray is a new format containing 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.
