Yes
My 13 card 1070 rig showed only use of 2.61gb of ram
I took a 4GB stick out and left it with 4GB ram and its running like a champ
But yeah this CPU core saturation issue is bad.
ah thanks will unplug the other 4gb next maintanance

so the core usage is high for unknown reasons ?
not sure. i can't even edit mine in windows.
is SSH enabled? what's the default username/password?
