Compatibility

To support maximum performance when using two bandwidth-hungry PCIe cards, Echo II DV T5 Rackmount requires the following:

• Two connections between the Echo II DV T5 module and the host computer(s) with two Thunderbolt 5 ports with independent PCIe bandwidth.
  
• For example:
  Mac (M4 Pro, M4 Max, M3 Ultra series)
  Some pro Windows laptops with two Thunderbolt 5 ports
  Connecting each card to a different Thunderbolt 5 computer

--------------------------------------------------------------------------

• Mac with Thunderbolt 5 ports
• Mac with Thunderbolt 4 ports
• Mac with Thunderbolt 3 ports
• Windows computer with Thunderbolt 5 ports
• Windows computer with Thunderbolt 4 ports
• Windows computer with Thunderbolt 3 ports

Technical Notes
1. Intel Macs with Thunderbolt 3 ports require macOS 15+.
2. USB4 support requires that your computer have a “USB4 Host Router (Microsoft)”. Navigate to Device Manager and expand the Universal Serial Bus controllers category to confirm.
