desktop memory

USA Southwest Region. My ASRock B450m Steel Legend / Ryzen 5 3600 apparently doesn't support 2166Mhz memory. This is what I have: https://www.newegg.com/hyperx-64gb-288-pin-ddr4-sdram/p/N82E16820104678 It is brand new, in the unbroken wrappers. I'd like to sell it outright for $170.00 shipped...
