If I install 2 m.2 nvme drives will it disable any sata ports? I had an older maximus board and it disabled sata ports 5 and 6. Read the manual but it states will only disable port 2 if im using a sata m.2 drive. Thanks for any help!

When I play games now with g-sync on my games will flicker pretty bad. Some games are worse than others. Then there are some games like Fallout 4 that don't flicker at all. Any ideas? Thinking my g-sync module might be going bad.
