I upgraded my pc with an i7 9700k cpu and Radeon RX 590 gpu. Didnt upgrade the motherboard, that's in the plans just short on greenbacks. My motherboard now is an ASrock z370pro4 I also bought 4 sticks of Corsair Vengeance LPX 8GB DDR4 DRAM 2666MHz (PC4 21300) (CMK16GX4M2A2666C16). On Asrock website they show they tested this RAM but to the right only shows 2pcs which I believe means just 2 sticks, Idk that whole guide confused me. My question is can I use all 4 sticks of this memory in an Asrock z370pro4 motherboard? Thanks.
