939 What power cable do I need for the Avid HDX card for the Echo Express III-D, III-R, or xMac Pro Server?Feb-16-18
The 3-card cable for the Mac Pro that Avid includes with HDX card also works in the Sonnet's Echo Express III-D, III-R and xMac Pro Server. Just replace the cable that is inside the chassis with the Avid cable. If you need a replacement cable, Sonnet has made a power cable for a single Avid HDX card that is compatible with these chassis. The part number is TCB-HDXB and is available from Sonnet or Sonnet-authorized resellers. (Note that the Sonnet cable supports only one HDX card.) If you need to power two or three HDX cards, you need the Avid replacement cable: ASY.CBL.POWER.MACPRO XD_CORE.TRIPLE REV.A, Part Number: 9180-60004-00.

1066 Matrox Cards do not support Windows 10 Fast Startup option.Sep-09-19
When using Matrox Cards in Thunderbolt Expansion chassis, you need to disable Fast Startup under Windows 10.

To disable Fast Startup, first, open your power options by hitting Windows+X or right-clicking your Start menu and selecting Power Options. In the Power Options window, click "Choose what the power buttons do."

If this is the first time you've messed with these settings, you'll need click "Change settings that are currently unavailable" to make the Fast Startup option available for configuration.

Scroll to the bottom of the window and you should see "Turn on fast startup (recommended)", along with other shutdown settings. Just uncheck this box to disable Fast Startup. Save your changes and shut down your system.
