hello.When I bought the motherboard(asrock fatality b450 gaming k4) i had problems with the memory at 3200mhz.so i update bios version directly to p3.50. I think my problem is that i didn't upgrade to p1.80 first and the to p3.50.So now im on p3.50 bios version.Ξ€here is some way to downgrade in p1.80???

Which bios version did the board use before?
What CPU and RAM are you using? Which problems do you have now? For a Zen or Zen+ CPU Version 1.80 (AMD AGESA AM_Pi_1.0.0.6.) should be the finest. Downgrade is possible, but not with the standard way... |

There is a way for a downgrade of the bios with the Asrock windows flash tool.
Watch this video (it is for another AM4 board, but just for understanding the procedure it doesn't matter): https://www.youtube.com/watch?v=ybj3XkteX9k&feature=youtu.be Without guarantee: The flash tool can update/downgrade several boards and must be configured - with changes in the ini file for your board and current bios version - and with the bios image you want to downgrade Folder structure: \AfuWin \ROM \ROM\ASRock.ROM <- must be replaced with the destination bios image ASROM.exe ASROM.ini Ini File: [ROM] Path=ROM File=ASRock.ROM [B450 Gaming K4] BiosVersion=P3.50 The tool, here for X470_Gaming K4: http://asrock.pc.cdn.bitgravity.com/BIOS/AM4/X470%20Gaming%20K4(1.90)WIN.zip Do you dare to proceed this way? If not, contact Asrock support or the user JZ (or _JZ) or here https://www.jzelectronic.de/jz2/index.php |

So again, what CPU and RAM are you using?
Setting the memory clock by just using the XMP profile isn't working properly in the most cases. And it depends on which CPU generation and which RAM you are using. Easy try: Increasing the DRAM voltage with 3200MHz from 1.35V to 1.36..1.38V may help to get stability (for example, for the RAM in my signature i must use 1.37V). More complex try: Use the Ryzen DRAM Calculator and it's documentation and howto's and get more knowledge for DRAM configuration. |

As i already posted: The video just shows the procedure which you have to understand! It's the same for all boards. I already posted the link to one flash tool. I don't know a link for your specific board and bios. The tool itself is always the same for each board, but you have to modify the ini file and the ROM image according to your board and bios version. Anyway, if this is to complicated for you, don't do it this way. Ask the Asrock support for a downgrade tool for your board. |

You also can lower the DRAM frequency. Just try it one frequency step lower.
Keep the SOC voltage on default, just increase the DRAM voltage a bit. If the DRAM calculator is too difficult, you anyway should use the Thaiphoon burner to read out the config data of your ram and post it here. |
