Received the 2133 speed ram... Makes no difference.   

What is the model of the 2133? Also, is this a replacement board? Mine works fine with my replacement board now and DDR4 2133 RipJaws. It could be your BIOS maybe? Im sure someone here knows what it could be or you can just call Gigabyte. I call them anytime I don't understand something

I was hoping to avoid a mobo replacement, and that different RAM would be enough, but that will be my next course of action.  My RAM is 2133 RipJaws V 2x8GB.  It's listed on the approved memory for this mobo.  I've tried flashing version F5, F6, and F7g of the BIOS and it's the same scenario with all of them.  Currently it's running fine on a single stick of 8GB ram, but I can't be satisfied with that.

Good luck getting your other issues sorted too.

Here's what I hadn't tried (until just now): Running both 8GB sticks in the same channel.  It works. 

So at least I have 16GB of total ram now, running in a single channel configuration.  I think I can live with this and hopefully a) the fact that dual channel doesn't work isn't indicative of a more serious underlying problem, and/or, b) Gigabyte will release a fix for this in the future.
