what is this error ?
GPU 0, GpuMiner k1a failed -55 ?
thanks
Show me your bat file or config you use than we can help!!!!
GPU 0 = you use one Card right ?
Try to set at least 16 GB of Virtual Memory
see OP FAQ:
Catalyst 13.12 is required for best performance and compatibility. Catalyst 14.x and 15.x are supported as well (usually 14.x/15.x are about 1% slower than 13.12), use appropriate version.
Set "GPU_MAX_ALLOC_PERCENT" environment variable as "100".
For multi-GPU systems, set Virtual Memory size in Windows at least 16 GB:
"Computer Properties / Advanced System Settings / Performance / Advanced / Virtual Memory".
I use one gup unit HD5450/2Gb
virtual memory on windows 8.1 set to 20000MB
Catalyst 14.10 was selected by AMD as bet fit
and of course i did set GPU_MAX_ALLOC_PERCENT to 100
my command line is NsGpuCNMiner -o stratum+tcp://xmr.pool.minergate.com:45560 -u muemail -p x -a 3
Use this in your command line NsGpuCNMiner -o stratum+tcp://xmr.pool.minergate.com:45560 -u muemail -p x -li 1 --add-priority-node this is a old card or ?
