Description

Within the Z Series, the Z840 Series Rackable Minitower Workstation from HP delivers extreme performance in a rackable 5U minitower form factor. This model of the HP Z840 series of workstations does not come with a graphics card, which allows you to customize it with your own. Once a dedicated GPU is installed, the Z840 is designed for professionals who require high reliability and is well suited for tasks such as intensive graphics, 3D rendering, multimedia, and gaming, as well as science and engineering applications. The system is powered by two 2.6 GHz Intel Xeon E5-2690 v3 processors, each of which is armed with 12 cores 24 threads, and 30MB of Smart Cache, all of which will allow you to run multiple applications simultaneously and provide significant performance gains when running multi-threaded tasks. If you need more power, the CPU can deliver extra performance by increasing the clock speed up to 3.5 GHz utilizing Intel's Turbo Boost 2.0 technology.

The 64GB of 2400 MHz DDR4 ECC Registered RAM allows the computer to run multiple applications simultaneously and also to quickly access frequently used files and programs. This Z840 is able to support eight 288-pin DIMM slots per processor, for a total of 16 slots. The current 128GB memory configuration is made up of 16 x 8GB modules, which can be upgraded to up to 128GB per slot for a total memory configuration of 2TB. As this RAM features ECC technology, it is able to help detect and correct the most common kinds of internal data corruption. This RAM is also registered and registered memory modules, also known as buffered memory modules, place less electrical loads on the memory controller and allow single systems to remain stable with more memory modules than they would have otherwise.

For long-term storage of your files, a 512GB SATA SSD offers quick access to your data. If you want to add external storage drives or other peripherals, the Z840 features eight USB 3.0 ports, two USB 2.0 ports, one serial port, and a PS/2 keyboard and mouse port. For users who wish to add additional components to the drive bays, the Z840 features four internal 3.5" drive bays and two external 5.25" drive bays. Whether you are listening to music, watching a movie, or playing a game, the integrated IDT 92HD94 audio controller outputs high definition audio and delivers higher fidelity than standard audio controllers. The Z840 Rackable Minitower Workstation is powered by an 1125W power supply.

Frequently asked questions

What does the warranty cover?

Our warranty covers all hardware faults, but please note it doesn’t cover accidental damage or software issues. However, we’re here to help with technical support for those matters!

At Reboot IT, we adhere to strict quality guidelines, ensuring that our refurbished products are not the same as used or secondhand items. We meticulously clean, test, and assess each device, replacing worn parts with high-quality components.
