Hi 2h4u, RelaxedCrypto, MineOrDie,
Our solver for 150,5,3 (Beam2) requires less memory than the 150,5 , but it will not fit on 3GB GPU Windows 10.
The miniZ v1.5p should be able to mine ZEL (125,4) on 3GB GPU Windows 10 (although still experimental),

According to your log miniZ is not picking the right mode, it should be loading mode 10. Try to add --mode=10 to your command line.
Cheers,
