How to achieve 3200g at 4GHz with all cores?
I successfully reached 4GHz on all cores in Ryzen Master under p95. Going up to 4100Mhz per core drops performance significantly, especially for the fastest core. To surpass 4GHz across all cores, would BIOS overclocking be a viable path? I have ample thermal capacity and a stable p95 performance after an hour, with a 56°C max temperature, so I’m confident the motherboard can support it—B450M-A II.
Voltage is likely the main issue here. You often encounter a wall of voltage that needs a big increase before things stabilize. It seems like you're likely facing this challenge.
I operate at 1700x with 4Ghz on 1.375V. Increase the voltage in small steps of 0.005V, then test at your desired frequency. Results might vary, as it depends on the silicon behavior.
I used 1.425 with 4100mhz and it’s not working well. 4ghz at 1.325v works consistently.
I believe 4 GHz is the maximum you'll reach. Running at 1.425V wouldn't feel good—I'd feel uneasy about that level of voltage, which could quickly wear out the CPU. The performance gap between 4.0 GHz and 4.1 GHz is probably too small to notice in everyday tasks.
the voltage is significantly lower than what pbo applies to most 7nm processors, often dropping to 1.525 or even higher at times. 1.425 works well for steady performance, especially on a 12nm chip. i understand the impact would be minimal, but i’m still aiming for it.
You're solid at 1.4v on 12nm. My 2700X runs consistently around 1.4v and higher. PBO support brings it to 4.1ghz at 1.410v. Most of the 14nm models reach near 4400–4500mhz, though hitting 1.6v was tougher. All Ryzen chips hit their limits when voltage isn't managed properly. The only guidance here is that pushing above 4ghz starts showing quarter-speed gains.
You'd start by heading into the BIOS settings, though you haven't used it before. You'll need to know how to access it from your system settings or power options.
