Even if the RAVENNA ASIO driver can run on any Gigabit Ethernet Adapter, including the onboard one, it is recommended to use a dedicated card.
Separate Network card is recommended for better RAVENNA ASIO performances.
Merging recommends Intel Gigabit network adapters.

For better performances, such dedicated network card can be configured, in Windows Control Panel > Network and sharing center.
Select Change Adapter settings, then right click on the card and select Properties.

Only the IP V4 protocol should be enabled on the RAVENNA card, so other Windows services will not interfere directly with the card.

 

In Windows Control Panel > Device Manager, locate the network adapters, select your card and access its Properties.
It is important to disable any power management feature.
Green Ethernet / Energy efficient Ethernet must be disabled.
It is usually in a Power Management tab, but it can depend of the NIC manufacturer - model :

  • Reduce link Speed during standby must be disabled (especially when using a switch on the RAVENNA network)
  • Wake on LAN  should be disabled also for dedicated RAVENNA network cards (not mandatory)

     

Additional Notes :

  • Jumbo packet is not supported.
  • Interrupt Moderation : can sometimes help to reduce sinks jitter when disabled (default is enabled)
  • Receive Side Scaling must be enabled (Default value).
  • Receive Side Scaling Queues must be set to 1  (Default value) (very poor performances with 2 queues)
  • Performances options : should be left to default values : Adaptive Inter-Frame Spacing Disabled / Flow Control : RX & TX / Interrupt Moderation rate : Adaptive (will have no effect if Interrupt Moderation is disabled) / Receive Buffers : 256 / Transmit Buffers : 512.
