CPU underclocking issue during reboot on MSI B350M Gaming Pro.
CPU underclocking issue during reboot on MSI B350M Gaming Pro.
Recently, I've observed that after rebooting (completely turning off and then back on each night), my overclock not only resets but also underclocks. It typically drops to around 1.55 gHz. My overclock was previously tested and stable. I'm using a Ryzen 3 1200 at 3.8 gHz with a voltage of 1.2875, running Windows in High Performance power plan. Any advice?
How did you verify your stability? It still appears unstable. Did the PC enter a boot loop upon powering it up? If not, it returns immediately to the default configuration—consider checking the CMOS battery.
I've seen some discussions about similar problems online. I'm not a specialist, just here to figure out how to boost my R3 1200's performance. It seems certain AM4 boards might struggle with specific settings, causing the BIOS to revert to slower speeds. My RAM works well at 2933MHz, but after a few shutdowns it drops back to 2133MHz—though 2800 is acceptable and my CPU performs nicely at 3.8GHz with 1.2V (it reaches 90°C). Can you try 3.7 or even 3.9?
1. How did you verify your stability? It still appears unstable. Did the PC enter a boot loop when turned on? If not, and it immediately returns to the default, check the CMOS battery.
2. Keep it running, it's better for the PC's longevity and saves energy while idle.
I tested AIDA64 for two hours and it performed flawlessly, with temperatures only hitting the high 50s. Also, it didn't start acting this way right away—it seems this issue has only recently appeared.
I've looked through some discussions on this forum about similar problems. I'm not an expert, just came here to figure out how to overclock my R3 1200. It seems some AM4 boards don't handle certain settings well—they reset the BIOS to slower speeds. My RAM works fine at 2933MHz and stable, but after a few shutdowns it drops back to 2133MHz. It's okay since it's around 2800 and my CPU runs smoothly at 3.8GHz with 1.2V (it needs 1.375V to exceed 90°C). Can you run 3.7 or even 3.9? I'll try and let you know.

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?
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.

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.

Same MB and 1600, never encounter this problem... Is your BIOS current?
