Asrock B450m Pro4-F double boot

Hi, my current system always does a double boot, as soon as I turn on my computer, fans go super fast then super slow then fast again then slow, after like 20 seconds, the Asrock logo appears then disappears, fans go fast and slow again, a few seconds later the Asrock logo re-appears, then subsequently goes to windows.

Also, I am stuck with 2666mhz on my RAM, I tried XMP profile 2.0 then adjusting to 3200mhz but the system gets stuck and then reverts to original settings with 2666mhz, below is my hardware:

Asrock B450m Pro4-F
Ryzen 5 3600
Corsair VENGEANCE® LPX 16GB (2 x 8GB) DDR4 DRAM 3600MHz CL18
Palit GTX 1070 Super JetStream

Lastly, I also tried the Ryzen Dram calculator with the safest settings but system gets stuck as well and reverts to original settings with 2666mhz

Is this a BIOS issue? or RAM issue? my BIOS is American Megatrends Inc. P1.40 5/9/2019

How will I resolve this? What should I do?

it is already running on latest BIOS, I checked Asrock's website.

you can try manually setting to 3200 and voltage to 1.35 (not XMP profile) and everything else to auto and if that works ... try a little faster or go down to 3000. Your RAM isn't on the QVL so you are only going to get what you get.

..and I'm assuming you have the RAM in slots A2/B2?

I've had pretty good luck with Ryzen 3000 series and non-QVL RAM (3 setups all running XMP profiles or faster) .. I had to run my RAM slower on same motherboards with last gen CPU's. You could get different RAM or you might have a dud memory controller on your 3600, so try another chip if these are all new parts and can be returned/exchanged.

My other setups:
Asrock B350 Fatal1ty Gaming ITX/AC w/ 2 x 16gb 3000mhz stuff carried over from my older 7700k build and a 3600x. Would only do 2866 with 2700x.

ASRock X470 Master SLI/ac before I upgraded to the x570 Steel Legend ran the 2700x with 4 sticks of 3200mhz RGB stuff at 3000mhz until I upgraded to the 3700x .. then I could run all 4 sticks at 3200mhz. Current rig in sig.

Asus B350 Prime w/ 4 x 3200 RGB stuff and a 3400g. System would crash with 4 sticks and a 2200g no matter what the timings were... and couldn't get 2 sticks to run at 3200mhz, had to run at 3000mhz

I honestly did not understand most of what they disccused on that thread , though I tried to changing the voltages as one person said that worked for him, it did not work on mine.
