Yes, that might have been it, but I'm surprised it caused such a disruption because 1) the clock speeds aren't that disparate, and 2) I even tried underclocking the fast one to match speed. Apparently the underclocking didn't work.
Seems to be okay for now.
DB, you may send me a spare watercooling setup in the mail, kthxbai.
