Any tips on boosting the 3800x performance?
recently achieved 3800x on crosshair x570 best oc, currently I reach 4.5ghz by adjusting the multiplier to 45. changed the fan curve and use nh-u14s for cooling. tried pbo and ez tuning wizard but pbo only hits 4.3ghz and tuning wizard is unstable. any advice?
Do you have the newest BIOS for AGESA 1003 abba? The PBO should perform significantly better. You're achieving up to 4.45GHz on a dual-core and 4.375GHz on others from your 3700x, which means you're getting at least 100MHz above that. If you kept the CPU voltage set to auto, be cautious—it might exceed 1.5v during full load. Regarding testing PBO values, what tools are you using? Some benchmarks may not apply enough load to trigger full PBO frequency; CB r20 is one such option.
i received bios 1001 after the ez update. the bus speed is 100 x 45 multiplier at 1.4v, but it remains steady across all cores at 4.5. can this be so simple? is this acceptable? when i run the user benchmark, i see a 10% improvement over the average with this chip. i haven’t changed the line load or anything—just adjusted the fan curve—and it’s still quiet. i upgraded from the fx8350 at 4.5, which was very hot; now it feels like an air conditioner blowing cool air.
Not used to that MB, but it will include at least Auto PBO or related options, such as the boost level range (1-10 on my machine) and the maximum boost in MHz (0-200MHz in my BIOS), plus the highest allowed TDP.
The REV number '1001' indicates an early BIOS version, which also implies an early AGESA release. Check the ASUS website for a BIOS and verify AGESA 1003ABBA. All-core overclocking on Ryzen 3000 models is challenging to achieve stable performance without significant cooling. Without reaching the rated clock speed, you lose the performance advantages of boost clocks.
Consider your specific needs: if you're working on a gaming rig, all-core overclocking isn't recommended since high single-core speeds will quickly reach their limits in games. However, with PBO and a slight positive voltage offset, you might achieve boosts beyond the rated clock, especially for top-tier CPUs.
For heavy multitasking like encoding or rendering, manual overclocking could be advantageous, but it demands excellent cooling solutions such as a Noctua NH-D14 or a 240mm AIO. It's wise to save a BIOS profile tailored to each use case if you plan to run multiple scenarios.
PBO is activated by setting the CPU multiplier to AUTO and VCore to AUTO, then adjusting its parameters in ADVANCED CPU settings to MAX: TDC, EDC, and PPT. You can also configure PBO SCALAR manually with a range of 6x to 10x.
Note: Additional stats from Silicon Lottery (https://siliconlottery.com/pages/statistics) for the 3800X overclocking are not available.
If your score is 4.5 on your 3800X with stable performance, you've definitely achieved a good result. Your current temperatures and wattage limits during heavy use are what make this possible. When running multiple threads or games, you're maintaining around 4.325 under full load.
