Rhino crashes when rendering whit CPU

Hi, i’m new in this fórum.

I have installed “Rhino 6” and “VRay 3.6 (for Rhino)” in two computers; the first computer haves the next specifications:

AMD Phenom II x6
NVIDIA GTX 1030 (2GB GDDR5)
16 GB RAM DDR3
128 GB Crucial SSD
Windows 10 1803

The another computer haves the next configuration

AMD Threadripper 1950X
NVIDIA GTX 1080 Ti (11GB GDDR5)
16 GB RAM DDR4
521 GB Kingstoon SSD
Windows 10 1803

The first computer (AMD Phenom) runs perfectly Rhino 6 and renders with Vray 3.6 perfectly using CPU and GPU and hybrid rendering, but the second computer (AMD Threadripper 1950X) work in Rhino perfectly, but only render when i use GPU, if I try use hybrid rendering or CPU rendering the computer freezes and I need rebbot for continue working, this is a big trouble I need continue working in Windows 10 cause there is not drivers for Windows 7 (I worked perfectly with previous versions of Rhino and VRay) this computer is so expensive, and my boss it´s annoying me, because I am not working.

Moved this topic to the correct category.

@mauriciotoo make sure you report to Chaos group, the maker of V-Ray.
