I don't think so?
775 seems to be harder on RP and RAS limits than Z97, but I don't have much experience with hypers tbh.
I tried to run PSC on phase yesterday for this. It was a total disaster. Couldn't boot C5 or PL5 @2000MHz, 21333C6 needed ~1.7V NB and didn't seem to want to tighten timings much.
