hello there,
if you have problems like : "Cuda error in func 'quark_blake512_cpu_setBlock_80' at line 701 : unspecified launch failure"
the problem is your intensity is set to high , lower intensity then try again , it will work i am playing with this miner on a MSI GTX 750 2 GB and get with algo xevan : 548.60 KH/s !
not bad for an GTX 750 2GB and its not the i version
[edit]
this error "Cuda error in func 'quark_blake512_cpu_setBlock_80' at line 701 : unspecified launch failure , has to do with your memory allocation clock on your GPU/CPU
Question >: can some one ex plain what this means in the miner > : [S/A/T]: 0/246/246, diff:
