MSI RX 6600 XT MECH 2X only getting 28 Mhs


Just wondering what I’m doing wrong with these Msi rx6600xt mech 2x cards, I’m only getting 28.7 MHs on each card. I see that most rx6600xt can get up to at least 30-32 Mhs. Can anyone help me with which better OC setting to see if that helps? I’m using phoenix miner.

Use NB miner v39.7
