Your 3900X overclocked to 4.0 GHz with only a voltage tweak, keeping other settings at stock. The results show the CB R15 score stayed around 3110, but the CPU voltage dropped from 1.478 to 1.304 and temperature fell from 45°C to 37°C. If you undervolt it manually, performance drops noticeably (score 2885). You're using the latest BIOS (AGESA 1.0.0.4). The issue might be related to the BIOS update or voltage calibration—consider checking the official documentation or reaching out to support for guidance. Thanks in advance.
I wouldn't consider 4.0ghz an overclock since your all-core turbo boost is probably similar, maybe just a bit higher. My 3700x with all-core turbo runs around 4.1ghz, and I can adjust it to 4.2ghz at 1.35v if needed.
It was boosted to 4.6 GHz from 3.8 GHz, but you reduced the clock speed, not increased it. Consider an all-core 4.4 GHz option, which should bring it back to the desired frequencies.
AMD configures the stock voltages to be elevated during idle, providing capacity for increased performance when needed. Applying a load causes the voltage to typically drop into the low 1.0 to 1.1 range.
Review your output voltages during idle or sleep modes using tools such as HWMonitor or CPU-Z. If you notice irregular spikes reaching up to 1.5V instead of the expected 1.325V (or your current setting), consider using Ryzen Master and keep it running in a minimized state while overclocking. This could indicate an issue that isn’t universal, but it’s worth investigating. I experienced spikes after applying overclock via BIOS or Ryzen Master; shutting down temporarily resolved the problem. Although default settings may show minor fluctuations around 1.45V, avoiding 1.5V spikes is important for stability. Running at 1.325V with a higher core count (e.g., 4175 ccx0 4225 ccx1) on my 3600 model reduced temps by about 3-4°C under load while boosting benchmarks by 6-8%. HWMonitor’s power draw remained consistent compared to the original specs. If your BIOS is outdated, you might still achieve lower temperatures with speeds above 4000, but older boards could benefit from a BIOS update to 1.0.0.4 for optimal performance and stability. Keep an eye on these details when planning your overclocking strategy.
