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 2018-10-24



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.


This system comes with an 8-core AMD Opteron 4200-series CPUs installed. Available is:

  • a high 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)

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

ECC Memory

ECC Unbuffered DIMMs this system comes 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 are included, which 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.


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.
