This was exactly the issue. I had it set to 1450 like I did on my previous video cards. I played around and it looks like 1458 is the cutoff. Any lower and it won't down clock. Thank you very much for the tip. Sending a beer your way.

I didn't even realize there was a cutoff like that. Is there a guide you'd recommend for setting up manual timing? I'd like to make sure I know what I'm doing and there's no other nuance I'm missing.

Thank you guys! I was trying to figure out why my cards(770s) weren't at there usual idle clock speeds for awhile now. I forgot I had adjusted the pixels to 1450 to stop a few lines from popping up onscreen when I upped the refresh to 120Hz. I changed it to 1458 and my cards idle where they should now.
