Also, MSI withdrew official support on all their boards for Kaby chips despite them being in the supported CPU list. If you check under specifications they aren't mentioning 7th gen CPU's. It'll work, but there may be some bugs is my thinking.
Check it out. All went a bit weird for a moment. Should be fine now tho
