Improve performance by boosting CPU speed on AMD systems.
Improve performance by boosting CPU speed on AMD systems.
On all 3000 series units, enabling EDC 1 increases performance for light tasks. The process involves: - Ensuring adequate cooling, which causes overheating. - Switching to manual PBO and setting EDC 1 while leaving the rest on auto. - Adjusting scaling to 10× and setting maximum clocks to 500 MHz within the PBO settings. Save the exit and open hwinfo64 to verify clock performance. You can increase clock usage beyond 100, but be mindful it may impact other devices. With this configuration on my 3900x, I can handle up to 4650 MHz across six cores and 4450 MHz on the remaining six. Setting the clock to 102 allows around 4750 MHz.
I never considered adjusting the base clock to achieve maximum performance on my 5900X. Normally it runs smoothly at 4.6GHz with a 1.4V supply. Pushing it higher caused thermal issues and crashes, even when submerged. I managed around 4.65GHz at 1.45V without breaking the limits. That was pushing thermal boundaries safely. I’ll revisit this technique at lower voltages and explore CCD OC options. For regular use, PBO/CO tuning will be key—though I’m still figuring out how to apply it to Zen 2.
Hello, please note the EDC 1 issue applies only to 3000 series models. If you increase the clock speed even slightly, crashes can occur and RAM performance may drop by 100 MHz. However, achieving solid results is possible. The 5800X3D can be fine-tuned via the clock settings and delivers strong outcomes. My 3900X runs in a continuous loop with specific pulse adjustments and additional cooling stages to maintain efficiency.
