Hey , hoping someone can help me with an annoying problem.  I have an ASRock AB350M PRO4 and Corsair Vengeance LED 16GB 2x8GB DDR4 3000MHZ C15.

I am able to boot at 3000Mhz through XMP with the 2.4 Bios.  I checked with cpuz in Windows 10 and I am indeed running the ram at 3000 with no problems.  Only thing is, when I reboot, the system turns itself on and off 5 times then resets to 2133.  I  have to reboot again after escaping the bios and then it goes back to 3000Mhz.  So in other words, I must do a double reboot everytime I reset or  power up my system in order to get my 3000MHz ram speed.

I tried different ram slots but find slots 2 and 4 works best.  Any idea whats up with this?  Anything I can do aside from downclocking my ram to 2666 to avoid having to double boot?  I tried the new bios 2.5 but with that, I can not run my ram past 2133.  2.4 seems to be the best bios at the moment.  I appreciate any help.
