Disclaimers
Intel's numbering is not a measurement of higher performance. Processor numbers differentiate features
within each processor family, not across different processor families. See:
http://www.intel.com/products/processor_number/
for details.
64-bit computing on Intel® 64 architecture requires a computer system with a processor, chipset, BIOS,
operating system, device drivers and applications enabled for Intel 64 architecture. Processor 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:
http://www.intel.com/info/em64t
for more
information.
Quad-Core, Six-Core, and Eight-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. Check with software provider to determine suitability. Not all
customers or software applications will necessarily benefit from use of these technologies.

SATA hardware RAID is supported on Linux systems that have support for the Intel RSTe technology. The
Linux kernel, with built-in software RAID, provides excellent functionality and performance. It is a good
alternative to hardware-based RAID. Please visit
http://www.hp.com/support/linux_hardware_matrix
for
RAID capabilities with Linux.
All drives must be identical in type and capacity.
RAID arrays greater than 2 TB are fully supported.
NOTE 1:
Requires hard drives with identical speed, capacity, and interface. Specific user-configured
hardware SAS RAID configurations are supported on this Linux system. For details, please visit
http://www.hp.com/support/linux_hardware_matrix

For details on the supported memory configurations on the HP Z420 Workstation, please refer to the
System Technical Specifications - System Board section of this document.
Each processor supports up to 4 channels of DDR3 memory. To realize full performance at least 1 DIMM
must be inserted into each channel.
The CPUs determine the speed at which the memory is clocked. If a 1066MHz capable CPU is used in the
system, the maximum speed the memory will run at is 1066MHz regardless of the specified speed of the
memory.

Double Layer discs can store more data than single layer discs. However, double-layer discs burned with
this drive may not be compatible with many existing single-layer DVD drives and players.
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
