good afternoon.
On the first versions when I first started using this miner, I could install on the cards Sapphire RX552 "multi_hash": 464 and the cards were given out at 520 h/s, but now I can not install more "multi_hash": 432 everything above the card is not keep the memory frequency and reset again and as a result the speed is from 0 to 60 h/s. The system did not change anything, tried to reduce the frequency to indecent 1800 MHz, the result was not given. Tell me what it can depend on, because it's on the forum guys use 464 on similar cards and I like everything hangs on the line
