HP Z640 Workstation

    The HP Z640 supports two Intel Xeon E5-2600v3 and E5-2600v4 series processors. The Hyper-Threading support allows two threads to run simultaneously on each core -- Windows recognizes 44 total cores on the Z640, 22 real and 44 virtual. It also supports "Turbo Boost" which automatically boosts the processor speed based on workload - so if an application is only using one of the 44 cores it will automatically increase the speed of the core in use and turn off the unused cores.

    The TDP wattage is the power supply consumption from each processor. Some of the higher performance processors consume up to 150w each. We recommend only one high performance processor in the Z640 considering the total power supply output. If you prefer to have two high performance processors, we recommend the HP Z840 since it comes with a higher wattage power supply and supplementary ventilation to support the heat.


    The single processor Z640 has 4 DIMM Slots supporting up to 512GB DDR4 ECC Memory.
    The dual processor Z640 has 8 DIMM Slots supporting up to 1TB DDR4 ECC Memory.
    Choose more memory to improve overall system performance.

    Footage / Project Files / Sessions / Scatch Disk

    For each industry, a dedicated fast drive to work from is recommended.

    • Video editing - footage / scratch disk
    • Photo editing - photo files
    • 3D Modeling / Eningeering / CAD - project files
    • Audio - sessions

    Choose the SSD to run light to moderate computations, audio sessions, 2D modeling, or edit 1080P footage.
    Choose the HP Z Turbo Drive to run large computations, 3D modeling, or edit 4K footage.
    Choose the NVMe RAID to run extreme computations, or edit 6K or 8K footage.

    Drive Bay 1

    The Z640 has two internal 3.5" SATA3 (6GB/s) bays. You can arrange any combination of hard drives or solid-state drives. ZWorkstations stocks only new condition and latest model Western Digital hard drives and Samsung solid-state drives.

    Optional: Adapter to split two 3.5" bays to four 2.5" bays allowing up to eight 2.5" SAS drives or SSDs. Manufacturer Product Page. Contact us to inquire.

    This section will be disabled if a solid-state drive in the Primary or Secondary Drive section is selected. Select an additional drive in Drive Bay 2 below.

    Hard Drive

    Optical Drive (Default)

    The Z640 chassis comes with a built in DVD Burner drive.

    Optical Bay (Upper)

    The Z640 chassis has two 5.25" bays to be used for optical drives, hard drives, or solid-state drives. One DVD Burner drive that burns and plays both CDs and DVDs comes standard.

    Since hard drives are 3.5" and solid-state drives are 2.5", the drive adapters are included in the listed price.

    Graphics Card (Primary)

    The Z640 mainboard has two PCIe Gen3 x16 slots available for the highest performing graphics cards and/or accelerators.

    NVIDIA Quadro Maxwell (2016 Release)

    NVIDIA Quadro Pascal (2017 Release)

    NVIDIA Quadro Turing (2018 Release)

    NVIDIA GeForce Ampere (2020 Release)

    Graphics Card (Secondary)

    Choose an optional second graphics card. Note that graphics cards work independently of each other. The benefit of a second graphics card is to support more displays or if you plan to perform multiple rendering or performance tasks at the same time.
