Well, I got a love affair going on with my Z390 Dark, with bios updates I was able to oc my Gskill Royal Silver b-die kit from 2018 to 4500Mhz CL17 on air which was really good for 2019 and for the 8086K's IMC which was not as good as the 9900Ks or Comet Lake's IMC.
I just believe if EVGA is listing 5333Mhz (and a plus sign after it) in the Z590 Dark specs, it should happen if not now then with the next bios update.
Kinda will make my mind up for Z790 and Raptor Lake next year - either Apex XV OR Z790 Dark.
Already running 5866Mhz "in total amazement" easy and stable on air so feel like I can skip Alder Lake and early DDR5.
Has anyone asked Jacob if 5333, 5600, 5866 are going to happen for the Dark?
My Z390 Dark wants a Z790 Dark big brother next year. lol
