Disabling SLI solves the issue, but keeps my frigging SLI disabled.
Contacted NH on Facebook and they don't seem to be responsive or attentive at all.
they are really big and simply don't care about the issue. you use your pc as a gamer you have 1 rig so you are small.
See if there is an easy way to toggle SLI on and off.
I have 4 rigs. One is at home and I want to use it too. I happily pay the fee for the service, and they did get back to me. There will be an update soon.
