Cuda 8 and gtx 640

[cuda9220]

Will this work with cuda 8 and gpu gtx640
If yes what will be make file command or compile command?

In fact, I made it work, but it's not worth using. GT 640 just Compute Capability: 3.0 with 384 CUDA cores, 2GB DDR3. Compute speed is lower than 10 Mkeys/s absolutely. Even P104-100 (GTX1070 Mining Edition) 8GB GDDR5X Compute Capability: 6.1 with 1920 CUDA Cores, Base Clock 1607 MHz compute speed around 325 Mkey/s only
