GPU GTX 1080 + Intel Xeon CPUs

I searched in the forum an google but I cannot found a solution.
I try to give a little bit more speed to hashcat by adding CPUs support.
I use hashcat-5.1.0, windows 10, and my hw:

2xIntel Xeon(R) Gold 6130, 2.10GHz,64KB,1MB,22MB,128GB DDR3-2666,Windows 10  64-bit,
1xGeForce GTX 1080 Ti,1.72GHz,448KB,2.8MB,0KB,11GB GDDR5-5505,Driver 431.36,

By using only GTX with nvidia drivers hashcat run ok, but after installing Intel CPUs OpenCL Runtime for Intel Core and Intel Xeon Processors 18.1_x64 the GPU will be unavailable, only CPU is available.

My question is if it's possible to use both CPUs and GPU and if yes how install correctly the drivers.

Thank you
Try reinstalling the gpu driver.

It run ok, thank you.
But the speed go down, initially 710 kH/s and  after 10 min to 600 kH/s
