Hi all
I purchased a Gigibyte Z390 Aorus Master, Samsung 970 EVO Plus, will be getting 9900k, haven't decided on CPU cooler yet, will be using a Seasonic 1000w
that I have aside. But I am confused about the RAM. I am looking to purchase G.Skill Trident Z Series but have no idea which frequency (MHZ)to buy. 3600mhz, 3866mhz, 4000mhz? Any help would be greatly appreciated. Thank you

9900k and the Z390 motherboard will both high RAM speeds. The difference between 3600mhz and 3866mhz is not worth it (corrent me if I'm wrong but it would be worth the higher speeds especially with an AMD cpu) with a Ryzen series cpu though it might be worth it. With your cpu I'd probably reccomend if your going all out and don't care about price to peformance 4000mhz is what you want but 3200mhz - 3600mhz would probably be th best match. The official ram speed for the 9900k is 2666mhz but the motherboard and cpu can both support higher speeds.

Or alternatively, you could save $400 and go with a Ryzen 2700x, little or no difference at 4k. It will also be zen3/zen4 compatible when those come out down the line, who doesn't like cheap upgrades?
 
Go for 3200mhz. Any speed above 3200 costs much more and generally performs only slightly faster since the faster kits have looser cas latency.
If you use memory intensive workloads, buy 3600 but for gaming a 3200 kit with like c16 timings is all you need.
