I have Nvidia 940M
How to change work-mode on Nvidia 940M ?

dont take windows taskmanager to serios when it comes to opencl/cuda

see output of hahscat, lines with "SPEED # 1,2,3

you are using 3 devices, unless you dont have any other graphic-cards inside your laptop? you are using CPU, GPU integrated and GF 940

you could check output of hashcat -I and see all recognized devices

if the gf 940 is not there, you will need to install the cuda sdk
