Hi All, Have been CPU mining ok for a while now and just picked up a MSI 7950 Twin Frozer III GPU. Having no luck getting sgminer to work. Have tried many different versions of sgminer with settings from many other users all with no luck. I continually get HW errors with all settings I try. Win 7 x64 AMD Catalyst 13.1 Driver: 9.14.10.0945 Interestingly Windows uninstalled my onboard graphics card after installing the 7950, so currently this is my only GPU. Not sure if this is an issue? Settings (sgminer 4.1.0) Batch File: set GPU_MAX_ALLOC_PERCENT=100 set GPU_USE_SYNC_OBJECTS=1 sgminer -k darkcoin -o stratum+tcp://stratum1.suchpool.pw:3335 -u abc -p def -I 16 -w 64 --thread-concurrency 8192 Error: [22:02:15] (5s):1.513M (avg):1.513Mh/s | A:0 R:0 HW:4 WU:0.000/m [22:02:19] GPU0: invalid nonce - HW error Can anyone help with 7950 settings? Cheers in advance!
