Disclaimers
When ordering two processors, the second processor must be the same as the first. Intel processor
numbers are 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.
Multicore is designed to improve performance of certain software products. Not all customers or
software applications will necessarily benefit from use of this technology. Performance and clock
frequency will vary depending on application workload and your hardware and software
configurations. Intel’s numbering, branding and/or naming is not a measurement of higher
performance.

Weight
Exact weights depend upon configuration (System weight only).
Minimum: 22.4kg (49.4lbs.)
Typical: 23.7kg (52.2lbs.)
Maximum: 31.7kg (70lbs.)
Temperature
Operating: 5° to 35°C (40° to 95°F)
Non-operating: -40° to 60°C (-40° to 140°F)
Humidity
Operating: Operating: 10% to 85% RH, non-condensing, 35° C maximum wet bulb
Non-operating: 10% to 90%, non-condensing, 35° C maximum wet bulb
Maximum Altitude (non-
pressurized)
Operating: 3,048m (10,000ft)
Non-operating: 9,144m (30,000ft)
Note: Above 1524 m (5,000 feet) altitude, maximum operating temperature is reduced by 1° C (1.8° F)
per 305 m (1,000 feet) elevation increase
Power Supply
Choice of:
1125W/100V/15A 90% Efficient wide-ranging, active Power Factor Correction
The power delivery system includes four 6+2-pin graphics power cables.
1450W/100V/15A 90% Efficient wide-ranging, active Power Factor Correction
The power delivery system includes four 6+2-pin graphics power cables.
1700W/200V/10A 90% Efficient wide-ranging, active Power Factor Correction
The power delivery system includes four 6+2-pin graphics power cables.
Notes: The 1125W/100V/15A (1450W at 200V Input Voltage) power supply can also supply 1275W of
output power when the input voltage is greater than 105V. If the input voltage is less than 105V, but
greater than 90V for any reason, the maximum power that can be drawn is 1125W. An uninterruptible
power supply (UPS) is highly recommended if 1275W output power is desired.
The 1125W Power Supply can also supply 1450W of output power when the input voltage is greater
than 200V under all conditions.
The 1450W/100V/15A (1700W at 200V Input Voltage) power supply can also supply 1550W of output
power when the input voltage is greater than 105V. If the input voltage is less than 105V, but greater
than 90V for any reason, the maximum power that can be drawn is 1450W. An uninterruptible power
supply (UPS) is highly recommended if 1550W output power is desired.
The 1450W Power Supply can also supply 1700W of output power when the input voltage is greater
than 200V under all conditions.

NOTES:
For details on the supported memory configurations on the HP Z8 G4 Workstation, please refer to the System
Technical Specifications - System Board section of this document.
Sleep (S3 state) support:
- Sleep (S3 state) may not be supported with non-HP validated and qualified 64 GB LR DIMMs.
- Sleep (S3 state) not supported with 128 GB LR DIMMs
DIMMs should be equally distributed across all six memory channels for optimal performance.
Each processor supports up to 6 channels of DDR4 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 2400MT/s capable CPU is used in the
system, the maximum speed the memory will run at is 2400MT/s, regardless of the specified speed of the
memory.
MT/s = Million Transfers per second
You cannot intermix LR DIMMs with Registered DIMMs. The system will not work.
The Z8 G4 is designed to work ONLY with DDR4 memory. The system will not work with DDR3 memory.

With Blu-ray, 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.
