Hi,

If anyone want to mine with AMD cards here is how:

1. Download Claymore's NeoScrypt AMD GPU Miner v1.2

2. Create a bat with this parameters

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

NeoScryptMiner.exe -pool stratum+tcp://eu1.arcpool.com:1121 -wal (your wallet) -psw c=BEPAY -a 2

(some cards can give more hash rate with -a 2 parameter try it, but some can crash if it crashes then remove -a 2)
