So recently, I have noticed that upon reboot (turning completely off, then turning on, ei. every night) my overclock not only resets, but underclocks. It will underclock usually to 1.55 gHz. My overclock was tested and stable. I am running a Ryzen 3 1200 @ 3.8 gHz with a voltage of 1.2875. Windows it on High Performance power plan. Any help?

1. How did you test your stability? Still looks like instability. Did pc go into boot loop when you turn it on? If not and directly goes back to default setting, check CMOS battery.
2. leave it on, better for longevity of the pc and idle doesn't consume much energy.

I have read a few threads on here with similar issues. I am no expert (I only came on here to work out how to overclock my R3 1200) but it seems to me some AM4 boards just don't like certain settings that are totally stable and reset the bios to slow speeds. I have the same issue with my RAM runs fine and stable @ 2933MHz but 2-3 shutdowns later it goes back to 2133MHz, lucky for me its fine at 2800 which I can live with and my CPU runs great at 3.8GHz 1.2V (needs 1.375V to go above and hits 90C). Can you run 3.7 or even 3.9 OK?

I ran AIDA64 for a 2 hour session and it was completely stable, with my temps only reaching the high 50c range. Also, it did not start doing this right away, it is just of recently that is started to have this problem.

New update! It completely surpassed me that 1.55 is exactly half of the base clock of 3.10 gHz. Also, after the computer rebooting the computer without overclocking, it went to 1.55 gHz as expected. I then got curious, and rebooted it once more, without touching any bios settings. The cpu on this boot was clocked to 3.10 gHz. This seems to be some kind of elusive bug on MSI's part. The boot pattern seems to be OC Boot -> Half Base Boot -> Stock Base Boot. Weird, huh? At this point I think the only solution is to either wait for an update for the bios, or just buy a new motherboard, as this bug was also reported elsewhere. I think I will go with the latter, as I am not impressed with MSI's track record so far.
