1. If you're looking to get all the fps out of your card it's good. The higher you go the more fps you will get.
2. Higher power limit vbios that could help with overclocking the card higher.

Push the card until it starts to crash then back off a bit until it's stable. That would be what I would suggest. 

Sajin
If your clock is being restricted because of the power limit then yes.

Sajin
No problem.

I'm guessing you were playing an older game at the time? GPU boost knows when the full clock isn't needed. An older game could cause that because it isn't demanding enough, and gpu boost knows it, so it doesn't fully clock up.

Sajin
Other things that would limit the clock would be the cards power limit, or temperatures. GPU boost also monitors those and adjusts accordingly.

If it's because you're hitting the cards max power limit then yes.

Sajin
After looking it appears your card doesn't have a xoc bios for it as it already comes with the highest power limit bios straight out of the box.

Sajin
No problem. Yes.

An unstable oc could be the source of your issues. Go back to stock to see if your problems go away.

Yep.

If you're talking about "hardware-accelerated GPU scheduling" then that should be on.
 
Hardware-accelerated GPU scheduling helps the operating system better manage how data is transferred between the CPU and GPU, which can lead to smoother frame rates and potentially further performance gains when combined with ReBar.
