Intel® USB 3.0
The Intel® C612 PCH has an integrated USB 3.0 controller which provides the four rear, one internal, and four front USB
3.0 ports on the HP Z840 Workstation. The Intel® C612 USB 3.0 controller provides cost-eective support for greater I/O
bandwidth than was provided by the HP Z820 solution. More information on the USB 3.0 Technology and Performance
measurements can be found in the “Resources, contacts, or additional links” section below.
USB charging ability
The HP Z840 Workstation equips the top-most of the front USB 3.0 ports with power charging ability. The port is able to
provide fast charge (up to 1.5A) to a portable device in the following states: System On, System Sleep, System Hibernate
and System O. It does not support charging in the ErP (Max S5 Power Savings) state. The port supports USB Battery
Charging Specication 1.2. The port is marked by the battery charging icon shown here. More information on USB
Charging technology can be found in the “Resources, contacts, or additional links” section below.
Thunderbolt™ 2

technology
The HP Z840 Workstation provides Thunderbolt™ 2 technology via the optional HP Thunderbolt™ 2 PCIe 1-port I/O card.
The HP Thunderbolt™ 2 PCIe 1-port I/O Card uses the Intel DSL5520 Thunderbolt™ 2 controller and provides a single
Thunderbolt™ 2 port.
Each Thunderbolt™ 2 port provides:
• 20 Gb/s data in each direction
• 12 W of power (2 W for cable, 10 W for bus-powered device)
• DisplayPort 1.2 capability with Multi Stream Transport (MST) support that enables the transport of multiple A/V streams
over a single connector
– Maximum 4096 x 2160 resolution at 60 Hz (8-bit display) or at 30 Hz (10-bit display) to a single display
– Maximum 3840 x 2160 resolution at 60 Hz (8-bit display) or at 30 Hz (10-bit display) across four displays
• Each of the four displays can support a 1920 x 1080 resolution
• 4K video le capture and display simultaneously
• Full backward compatibility with Thunderbolt™ 2 devices
For more information on Thunderbolt™ 2 technology, benets and installation, please refer to the “Resources, contacts,
or additional links” section at the end of this document.
I/O and storage
Internal I/O
The HP Z840 provides a total of seven high-performance graphics and I/O slots. An additional bulkhead allows for an
eighth mechanical-only I/O card (e.g. SDI card).
In a single processor conguration the HP Z840 provides two PCIe3 x16 and one PCIe3 x4, and one PCIe2 x1 dedicated
electrical slots. In a dual processor conguration, the HP Z840 provides an additional PCIe3 x16 and PCIe3 x8 electrical
slot. In addition to the dedicated slots there is another slot which serves as a PCIe2 x4 in a single processor conguration,
but is automatically upgraded to a PCIe3 x8 slot when a 2nd processor is present.
The HP Z840 provides an internal 1-port USB 3.0 connector and an internal 2-port USB 2.0 header.
