-a scrypt:1048576
now my line is:
cpuminer-core2.exe -a scrypt:1048576 -o stratum+tcp://verium.graymines.net:9333 -u VJbXXXXXXXe1a64 -p x
But I get err - Scrypt buffer allocation failed
I did have the same problem at one point. A reboot fixed it for me. Not all cpuminers will work with scrypt:1048576. Which one are you using?
