NAMD2.12b1 and CUDA

From: Jeff Comer (

NAMD2.12b1 runs on my GeForce GTX 960 GPUs but not on my GeForce GTX
770 GPUs. I tried adding "useCuda2 no" and "usePmeCuda no", but I
continue to get this error:

Charm++ fatal error:
FATAL ERROR: CUDA error Error executing CUDA kernel
read_CUDA_ARCH_kernel in file src/
Error string: invalid device function
Possible cause: Device compute capability is less than the compute
capability the code was compiled for.
 on Pe 4 (conejo device 0)

Is there a solution to this?
