What miner and driver are you using? I have a Galax 1660 non super non TI with hynix* gddr5 and I can’t get more than 22.57 mhs on T-REX with N460.67 drivers.
*I think its a hynix mem, it appeared one time “Hynix GDDR5” and now it only appears “GDDR5”
another strange thing is that it shows 5942MB not 5944MB.
