I'm building a new rig with ASRock's Creator x299 motherboard. This will be for video processing. Currently I have G.SKILL Ripjaws V Series 64GB (4 x 16GB) 288-Pin DDR4 SDRAM DDR4 2133 (PC4 17000). I want to update to 128GB. Should I purchase a second set of these, or is there something else I should be looking at or recommended?
