Hello,
I have a RIG with a RX VEGA 56 and other 7 GPU (RX470 and RX480), when I run all toghether with Cryptonigh I have jus 800 H/s on VEGA, but in other PC just with 1 GPU RX VEGA the hasrate is 1950 H/s why this different behaviour ?
To clarify what the previous poster mentioned, you will have to use 2 separate miners.
1 miner specifically for your 470/480 cards
1 miner specifically for your VEGA 56
For the 470/480 cards you can use claymore's cryptonight miner
For the VEGA 56 you can use Cast XMR
I have use two different miner Cast XMR for Vega and XMR-stak for other RX but I had the same result !
then on Radeon tool I can't set the HBCC, just enable and is not possible select the amount of memory that now is fix at 9GB while previous was 15GB.
I think is not possible use both card on same rig, anyone have this mix card RIG working correctly ?
