Technical white paper | HP Z640 Workstation
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 Z640 Workstation. The Intel® C612 USB 3.0 controller provides cost-effective support for greater I/O
bandwidth than was provided by the HP Z620 solution. More information on the USB 3.0 Technology and Performance
measurements can be found in the "Resources, contacts, or additional links" section at the end of this document.
USB charging ability
The HP Z640 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 Off. It does not support charging in the ErP (Max S5 Power Savings) state. The port supports USB Battery
Charging Specification 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 at the end of this document.
Thunderbolt™ 2
The HP Z640 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 4 displays
• Each of the 4 displays can support a 1920 x 1080 resolution
• 4K video file capture and display simultaneously
• Full backward compatibility with Thunderbolt™ 2 devices.
For more information on Thunderbolt™ 2 technology, benefits 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 Z640 provides a total of five high-performance graphics and I/O slots.
• The HP Z640 provides two PCIe3 x16, one PCIe3 x8, and one PCIe2 x4.
• When in a single processor configuration an additional PCIe2 x1 dedicated electrical slot is available.
• All slots match the mechanical lengths to their electrical lengths and are open ended.
• The HP Z640 also maintains a single PCI slot that is derived from a PCIe to PCI Bridge that brings the total number of I/O
slots to six.
• The HP Z640 provides an internal 1-port USB 3.0 connector and an internal 2-port USB 2.0 header.
