Intel Apollo lake defines power constraints for the processor.
That's what I said originally lol. It's a hardware limitation. It's a non-K CPU so it's set in firmware. It also lacks FIVR which is required for software voltage tweaking. Unless you re-write the CPU firmware you're not going to override it.
Power PL2 is configured at zero watts, instructing the CPU to apply throttling limits. Disable all controls and boost both PL1 and PL2. The CPU multiplier maximum remains fixed, while turbo power caps stay unlocked. Power boundaries aren't configured properly; they can be increased. @Octa Lucilfer Share a screenshot of the main ThrottleStop interface. Typically, SpeedStep must be activated on these older chips to achieve full performance. The PP0 Current Limit is fixed at 31, and altering it to 1023 isn't feasible. Restore it to 31. Values locked by the BIOS cannot be modified.
You're wondering if boosting the turbo frequency by a few watts will really improve performance, maybe just a small increase of 1-2%. It does seem risky, doesn't it?
The expected performance boost is likely overstated. A N4200 operating at its minimum frequency is around 1.1 GHz. Boosting turbo power could push it up to 2.5 GHz. A 125% CPU speed improvement is a worthwhile goal. Boosting package power may also help the Intel GPU sustain higher speeds longer. Why? The CPU runs at 62°C, and throttling begins around 105°C. There’s ample room to raise power limits. Exceeding the 6W TDP with higher turbo isn’t harmful. Some users set limits up to 15W, potentially doubling iGPU performance. It remains an older processor compared to modern Intel chips, but raising limits could determine usability. Not everyone can afford the newest hardware. The forum discusses ways to extend turbo limits for devices like the EzBook 3 Pro.
I wonder if altering the BIOS can affect the PP0 limit either through a hidden option that users can set and modify using AMIBC or by tampering with the BIOS code itself if it exists. For non-OCABLE locked CPUs without voltage tweaks, this idea doesn’t hold up. You can push the system to its maximum for years without problems, which seems to be around 105°C. Surprisingly, it works out to about 100°C or higher, but it’s okay as long as you run it at full capacity for a decade or more. Even though performance might drop, it won’t be obvious until about ten years later. The real risk comes from heat, especially if the chip can be overclocked or voltage adjusted. At 1.5V at 95°C it’s better than 1.2V at 105°C, since both voltage and temperature together impact wear. Running it above 80°C is safer to prevent rapid degradation.
Thanks a lot! Thanks to you, my CPU isn't throttling at all. I ran a CPU stress test for over a minute and it kept at 8 watts with no core power limit breached. You're awesome!
Don't overlook the Pentium N4200, it actually outperformed many new Celeron chips with four cores and ran smoothly at 10 watts without any issues. During benchmarking, it reached its peak performance but briefly hit a limit for a short time. However, it can surpass those scores when conditions are right.
