The RIVE is geared for Liquid Nitrogen benching. It is a bencher board. Simple as that. And if you are not going to be benching, then really do not see the point of spending all that money.
🙂The Formula board is my favourite board for gamers, and the Deluxe is feature rich and just so solid.
Yes you can. It will be a very poor CPU that does not run ram at 2133MHz. The CPU determines how high or how well the memory is clocked. So I can quite confidently say if you go for a single kit of quad channel 2133MHz ram then your system will work. Important part is single kit.
