When the ram is not stable it's not uncommon for it to lose recognition, you'll need to do some tweaking for sure.
Did those settings help at all or at least get you closer to 3600MHz? The rampage v extreme supports ram speeds up to 3300MHz and can go beyond if you have a cpu with a good IMC but 3600MHz might be pushing it.
I'm sure you're tweaking it now so give us an update. 🙂
