Yes, these are from the Gigabyte website, however, it's not up to date. I have even more up-to-date drivers than the ones listed (as below)
From the INF installation:
When I ran the Intel Driver Update Utility Tool:
It states "This version is valid" rather than "Your Driver is current"
So the Gigabyte driver page is not up to date and the Intel Utility is telling me there is a more current Chipset driver available.
