clocking motu 828 and rme hdsp

Hello, I have the rme card adat connected to motu 828 for converters in and out. I know that I need a better AD/DA setup eventually. For the time being, however, should I be using word clock on such a small setup? Or is the steadyclock of the RME sufficient? Rme is clock master and Motu is slave…Thanks…Duke
