That fact that it is 2133mhz is what would cause it to be slow. Ryzen platforms don't perform well with anything slower than 2933mhz, preferably 3000-3200mhz memory if you want to see the proper performance from your Ryzen chip due largely to the way the infinity fabric architecture works. Slow memory generally equals comparatively slow CPU performance.
Obviously, you CAN use slower memory, but anything below 2800mhz is going to incur a serious performance penalty on any Ryzen platform.

i dont wont to go through any hassle i just want to build it, and for it to work the first time with no complications.
That, is a very good reason to NOT go with a Ryzen platform. Ryzen is a good platform considering it's price vs performance metrics, but usually it is neither hassle free nor as fast as Intel platforms, but it's usually significantly less expensive which is why many users are willing to deal with it.
BIOS updates over the last year have improved things tremendously, but it is still often not just a plug and play affair if you want to see decent performance for the money you spent. Sometimes it IS that way, but often it is not. Buying memory that has been user verified to work at the rated speed, not just at the default speed like the manufacturer QVL lists, is the best way to ensure this.
So again I'll ask you, what is the MOST you are willing to pay for a motherboard and memory kit, in order to try to avoid hassles later.
