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?
Building a reliable PC involves more than just assembling the parts. You need to be able to configure all of the BIOS settings appropriately. This can be quite involved and frustrating as it can require a lot of trial and error with stress testing. It is however often the only means to get a 100% reliable PC.
