Hello
I have one msi gaming x rx 470 8 gb and one sapphire rx 470 4 gb on my system.

When I try to start  the miner both cards are identified as Ellesmere 3072 mb and then it quits after saying POLO/SOLO version but when I start it through nicehash gui both cards are identfied correctly one 8192 mb and the other 4096 mb and it starts mining without a problem. Ive attached a screenshot for both cases.

This is the command line Im using

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

EthDcrMiner64.exe -epool eu1.ethermine.org:4444 -ewal <Your_Ethereum_Address>.<RigName> -epsw x

Could anyone help me figuring out what im doing wrong. Thanks
