Over .50 efficiency on hiveos, all invalid shares on Hiveon?

Set up 2 3070s using hiveos on Phoenix miner. Ran like a champ, zero invalid shares and over .50 efficiency.
Switched over to hiveon miner using pheonix miner, ALL invalid shares using same overclock settings.
Re-overclocked on hiveon and same thing. Shit wont find shares at all.
What gives.?
