LTT recommended Asrock B450m Pro4 Ram Issues

[JeremiahChub]

Hey All,

I've got a problem that is driving me freaking up the wall. I have an ASRock B450M Pro4 motherboard, Ryzen 3700x, 32gb of Corsair Vengeance Ram (8gbx4), and after an uncertain number of bootups, it will power cycle itself like a failed overclock, and lose the XMP settings. I am on Bios version 4.90 (Latest revision), and I've tried versions, 4.60, 4.30, and 4.20, and it doesn't resolve the issues. I've also ran Memtestx86 on it, and let it run overnight and no errors found. Still having the issues. It keeps defaulting back to 2133mhz for the memory speed when it does this. Can anyone help? Hoping Anthony might see this since he did the video on this board, and might be able to help or at least throw in his 2 cents.

Any help is welcome as long as I can get this to quit doing this. Thank You!

Are any other settings in the BIOS changing or is it only the memory? If other settings are resetting to defaults then replace the CMOS battery.

If it's only the memory then try doing the memory speed, timings, and voltage manually instead of with XMP. Might need to run them a bit slower too. What speed is the memory kit?

only memory. it's a 3200mhz kit.

then don't use xmp (it doesn't always work) and try to tune it yourself

(or just set the xmp and then step the speed of the memory down to 3000mhz or sth like that)
