Reduce clock speed by 30% for better efficiency.
Reduce clock speed by 30% for better efficiency.
I applied undervolting on my Asus x570-I BIOS, adjusting the negative voltage offset to around .0425. This helped lower temperatures by about 5°C. The Ryzen processors tend to get hot when PBO is turned on, so I kept the voltage low enough to avoid spikes above 80°C for short bursts.
He experienced significant drops in performance after doing that.
I've just completed some adjustments on my 3600. I set the voltage to 1.2 and began increasing the clock speed. A 4.3 GHz frequency seemed steady at that setting. The Cinebench R20 ran smoothly at 4.4 GHz with 1.2V, but it crashed during the second test and had to restart. I settled on 4.35 GHz, reducing the voltage to 1.25V, which gave a Cinebench score of 3966. This suggests the clocks are accurate. The temperature stayed lower than normal, around 40-50°C, with ambient around 22°C. I used the BIOS for these changes and kept the stock cooler; it performed well. I tried Ryzen Master but felt it wasn't responding properly. My cooler is decent but not great, so I opted for an affordable AIO. The 3700X should be better built and paired with a top-tier cooler. For 4.2 GHz, 1.1-1.15V might work. Experimentation is key—voltage matters, higher speeds are better, but find the right balance for stability. Adjust gradually and test until you reach a reliable setting.
I figured it out myself. Starting at 4200mhz with 1.2 volts wasn’t working well, so I increased it to 1.25 but realized that might be too high. It seems lower is better—around 80°C at 20°C max temp. At 4000mhz running at 1.175V, it’s stable for about 30-40 minutes on the blender benchmark and Prime 95. In Blender benchmarks, 3700x stays solid up to 70°C flat, while P95 hits 85°C. I’m using the stock cooler.
Prime95 demands heavy processing, making 85°C acceptable at the highest levels, while 70°C appears reasonable. How about the idle temperatures?
I attempted to lower the voltage in Ryzen Master and achieved a stable score of 4936 Cinebench at 1.1375V on your 3700X with 4.2Ghz all-core. This performance has remained consistent. Now I'm considering adjusting the BIOS offset instead, but my clock still stays at 3.6Ghz and it doesn't ramp up as it did before. Can I skip the undervolting and preserve the boost settings?
You need to revert the BIOS settings that were changed during the update. Since you disabled the undervolting, you should restore the original BIOS values for the BIOS settings to regain the previous performance behavior.
