You might be right. I havent had the time to play with my MSI board yet, only testing boot time, but I can confirm that my 3200-16 Ripjaws V isnt stable using XMP settings on the ASUS Z170 Deluxe board. I have two sets, and I use the system for playing League of Legends. Benchmarking seems fine, but when play, it occasionally crash. So Ripjaws 3200 isnt plugn play on Deluxe. My Kingston works fine.
