I have just purchased a 9900kf and an asus prime z390-p. Now I want to discuss memory. I do not intend to rev this new build past 4.5ghz so can someone advise me as to what would be adequate for my needs. I run dcs world and 3 other flight simulators. The graphics card is a gtx1080 8 gig. I am an absolute noob when it comes to memory clock speeds. What do you consider would good ram for this build?
