• D8 Mainboard FSF RYF-Certified


Unleash new levels of work, action and intensity with powerful and libre software inside. Designed to give you the main building block for a modern computer that fully respects your freedom.


The Free Software Foundation's "Respects Your Freedom" hardware product certification


The Vikings D8 mainboard fully meets the criteria for the FSF's hardware endorsement program and was certified on 2019-02-07



Boot firmware - Libreboot & coreboot

The Vikings D8 comes with coreboot or Libreboot. Both make use of SeaBIOS and work perfectly fine. That being said, Coreboot has a more up-to-date codebase and as such we choose coreboot as the standard option.

One of the good things about having a libre-friendly system is that you can replace the boot firmware from the user-space of your operating system. This is fairly easy even for the untrained and Vikings can send instructions on how to do that. What's more, you can order a 2nd chip (2M PDIP) for swapping your boot firmware or for other testing purposes.


The D8 mainboard does not include a mini-fan for the southbridge/PCIe bridge and is required in most setups. If you're looking for a complete system that includes all parts, please check our D8 Workstation.

CPU(s) (optional)

This system is available with an 8-core AMD Opteron 4200-series CPUs installed. There are three options:

  • a highly performant (95W TDP) 8-core Opteron 4284 CPU with 3.0/3.3/3.7 GHz (base/full load turbo/half load turbo)
  • a highly power efficient (35W TDP) 8-core Opteron 4256 EE CPU with 1.6/1.9/2.8 GHz (base/full load turbo/half load turbo)
  • no CPU

You can order the Vikings D8 with a second CPU, so 16 CPU cores will be available. CPUs are subject to availability.

Heat sink/fan isn't included! If you're looking for a complete system that includes all parts required for operation, please have a look at our D8 Workstation/

ECC Memory (optional)

ECC Unbuffered DIMMs this system can come with, contain error correction code (ECC). ECC parity helps detect and correct single-bit memory errors, which can cause sudden shutdowns, file corruption or data loss. Help prevent costly (or annoying) downtimes, which also ensure a higher level of data integrity.

8GB of ECC RAM is generally a good starting point for most computing needs in the office and at home. You can upgrade RAM in 8GB increments to suit additional needs.

Graphics (optional)

An Nvidia Geforce GT 710 with 1GB DDR3 RAM, HDMI and DL-DVI-D interfaces is available for office use and the occasional game. It has a fanless heat sink and is absolutely silent.

USB3.0 - TUSB7340 (optional)

This  USB3.0 card doesn't require firmware and is, from the security standpoint, much better than other options currently available on the market that often pose security risks.

Audio (optional)

The ASUS MIO Audio 892 sound card delivers a high definition audio experience. With an enhanced signal-to-noise ratio and 7.1 surround sound, this card offers great sound quality and complements the robust video power of this workstation.

Refurbished Certificate

The D8 mainboard and the optional CPU are refurbished/used parts. Vikings does rigorous testing of all parts and also gives a comprehensive guarantee for all parts of the system.


Peace of mind - legal and commercial guarantee options

Vikings offers two service packages for the D8 Workstation:

  • 2-year E.U. legal guarantee (included): conditions see vkgs.io/eulegalguarantee
  • 3-year commercial guarantee: Extension of the E.U. legal guarantee to three years, waiver of the reversal of the burden of proof and payment of postage costs towards the customer for the entire period.
