No it's not a CPU issue it's typically a mobo/BIOS issue. Numerous people have reported this same problem to ASUS on this specific model mobo (and others), but Asus doesn't want to admit their mobos are extremely RAM sensitive. If you badger Asus enough they will release a BIOS update to allow your RAM to function properly all the time.
You should also contact Corsair as they are probably aware of the issue but the ICs they are using might vary slightly from one batch to another, thus causing a conflict on the Asus mobos, which IME have always been RAM sensitive over the past 20+ years.
In addition Asus uses multiple companies to manufacture their mobos so it's possible one of them has some mobo production issues also?
Technical ignorance is NOT a destiny it is a choice. Do your homework so that you can make technically informed decisions and not be duped by advertising hype or mis-information stated as fact when its not.
