I7 8700 struggles to reach full CPU frequency under maximum workload.
I7 8700 struggles to reach full CPU frequency under maximum workload.
The minimal CPU activity probably stems from hardware limitations, and there’s little you can do about it. Restart the BIOS to verify and look for any available settings, but this issue is typical on devices like this. Running lighter tasks or a single-threaded operation should increase performance.
Task Manager shows low utilization when the CPU is busy, suggesting throttling. Close Task Manager and HWiNFO, then try ThrottleStop 9.6—it helps diagnose and resolve these issues. https://www.techpowerup.com/download/tec...ottlestop/ Review the FIVR and TPL windows to understand BIOS settings. Capture a screenshot of ThrottleStop’s main screen with the Limit Reasons window active while Cinebench runs. The window will highlight power or voltage regulator throttling. Sometimes it’s just a BIOS configuration problem; your BIOS is 5 years old—check HP’s site for updates.
Clocks reach their limit per core while the PC is idle, but they don’t behave this way during heavy usage. That’s typical. I’ll follow the same approach when I have more time.
4.6ghz is just a single-core boost. 4.3ghz across all cores works well under heavy load, actually, the more demanding the workload, the slower the clocks tend to be since you need to energize more of the processor.
Your boost frequency is expected to fall to around 3.2GHz after the PL2 phase ends, which is about 28 seconds from now. Yet you’re not seeing that level of performance, and it’s dropping further to just 32W. This suggests something more is affecting your system than just power limits. Based on what I understand, the VRMs on your motherboard might be throttling due to excessive heat, limiting how much power they can safely deliver. Could you provide a photo of the internal components? That would help us assess the cooling situation.
Examine the main turbos: one core at 4.6GHz, two cores at 4.5GHz, three cores at 4.4GHz, and four or more cores at 4.3GHz. When you have eight threads or more, it will only boost up to 4.3GHz. This is typical behavior. I don’t know about the other problems you’re facing.
I misunderstood the request. The problem isn't reaching 4.3GHz—it's not even achieving higher speeds.
@frozensun ThrottleStop Limit Indicates BD PROCHOT issue. The processor only reaches 2260 MHz instead of operating more quickly. Consider removing the BD PROCHOT section from the main ThrottleStop display. Review the metrics. His CPU performance is unusually slow.
