yeah. it looks like that is the latest available version. I went and checked for an alternative version that might be slightly newer on the motherboard page as well as the page for a strix card.
Try uninstalling the software and reinstalling it.
Or try one version lower in case this is a bug that's only in the latest version.
Or perhaps it's just cuz your CPU is pegged for a hot second like that and it causes it to skip a beat for it.
I personally never had a sync issue with the Z170 board and an a Strix 1070 that I had in the past on one of the version 1.6 something or other of Aura Sync.
