Nvidia 550Ti Sleep / Wake / Freeze Thread

[saribe0]

I have the 550 TI paired with the mob GA-X58a-UD3R rev 2 and I'm getting lock ups whenever I use FCP X. My system boots fine here's my plist: Oh btw I'm on Yosemite.

Did you do anything else to get the card working with Yosemite??

My card turns off when graphics are supposed to load while booting up. I've tried using the plist you included but am still running into problems.

I've also tried the web drivers without luck. Though my graphics card doesn't turn off with them, I'm left at a blank grey screen before the login screen.
