  • Depending on the server configuration or specific orders, the riser card can be a Gen 4 or Gen 5 card.

  • This section only breaks down how to match the cards with the brackets as the appearance and the installation methods are the same for the Gen 4 and Gen 5 BF cards.

This card can be:

  • A Gen 4 riser 1 card

  • A Gen 5 BF riser 1 card with one slot removed
