Im using two cards atm on my Asus p5w dh delux,
1st gpu RX 470 4gb
2nd gpu RX 480 4gb
when I run miner with settings like this:
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
ethminer.exe -F
http://us-west1.nanopool.org:8888/0x2081E2AC5f5ea9823D71DF26cC98969aFeE468C9 -G --farm-recheck 200 --cl-local-work 256 --cl-global-work 8192
I got only 40Mhs, with only rx 470 i had 24Mh/s. Should I install different drivers for each card or change miner settings.
Thank you for any advice
