Set Sync ID on MASTER server layer 1 to Sync D 1

Set playmode on SLAVE server to Sync ID 1

Both files 'should' play in sync.

However - The file is quite large - so you should also ensure that both servers are identical to get best results and the file is encoded in a sensible codec (AIC)
ie same spec / OS / SSD / Graphics Card

Does the file playback normally on each Mac without dropping frames?
What is the data rate?

Can you describe your setup in more detail?

SSD raid dont usually make much difference. It would be worth testing with and without RAID to see if there is a difference in your cofiguration.
