Issue with ASRock - Fatal1ty B450 Gaming-ITX/ac, Ryzen 3700x and Ram G.SKILL F4-3200C14D-16GVR Bios is updated to 3.30. At first CPU didn't start at all. But after some RAM juggling and BIOS reflashing I've managed to boot once. So my boot sequence is following: I power on the PC wait until MB bootloops for 3 times and then start after 1 minute delay. The RAM frequency auto-sets to 2400mhz/1.2v If I set any other option it then resets back to auto after some bootlooping. Is there anything can be done? Are there any BIOS updates in future for more RAM support? |

| On mine it posts after countless boot loops if ram is anything beyond 2133Mhz (my sticks run at 2400 by default). But somehow today after some complete power-off (unplugged) time, it begins to boot loop even with 2133Mhz. Guess we all have to deal with it for now... At least I can get it to boot with patience everyday in the morning, use it for a day, then do it again the next morning... |

| I think someone on Reddit r/amd just received a new beta bios from ASRock that supposedly fixed this. Maybe it's soon... |

I tried this L3.33 bios. No success as well. RAM resets to 2133mhz/1.2v when trying to apply anything higher than that. Setting FCLK to 1433mhz don't work out. |

So I had to roll back to 3.30 bios. Set FCLK=1066, MCLK=2133, VRAM=1.35 It?™s the only option II can post without issues right now. Anything higher causes bootloops. RAM gskill ripjaws v 3200c14 |

i know zen2 have higher ram compatibility but i guess its best to use RDC to set those sub timings since your kits arent ryzen certified. unless you are lazy then set everything to auto and let the bios decide instead of forcing it to run xmp btw my initial results with agesa 1003 on a zen+ i'm bootable in 3533 i didnt tinker with it that much because the volts required is over my comfort zone -------------
