Here is the scenario. Im running a Ryzen 3 1200 on a MSI B350M Gaming Pro Motherboard with a stock cooler. Ive seen multiple people say they have been able to hit 3.9ghz at 1.29v, so I tried it myself. Wont even boot into windows. So i worked my way down from 3.9 to 3.8, and it booted into windows, but crashed as soon as i started up cinebench. From 3.8 i went to 3.7, which booted into windows, and ran perfectly. So i called it a night and went to bed. The next morning i turned my pc back on, ran cinebench and checked hwmonitor just to be safe, and it underclocked itself to 1.55ghz. Why? No clue. I restarted it multiple times, i even went back to deafults on core clock and voltage and it was perfectly fine. So any ideas? Is 1.29 too much for 3.7ghz? Thanks beforehand.
