Blck Spread Spectrum技术用于扩展信号的频率分布。
What processor are you using and what clock speed are you observing? Are you applying the Windows High Performance power setting? Most differences in the reported BCLK readings stem from monitoring inaccuracies. Under accurate measurement, my Z490 board maintains a consistent 100.0000 MHz. Consider enabling ThrottleStop. Adjust the FID column header in the monitoring table; it will refresh the BCLK calculation each time. Are you noticing any notable changes?
It's running at 10,900kf with a 5.2ghz base. I'm using a high-end plan and haven't encountered any problems. The variations I notice are small but noticeable. Usually, I expect consistent even figures like 4500, 5000, 5200, etc. In games and monitoring tools, these often round down to 4995, 5198, etc. It's just a minor quirk. Another thing I've observed is that when the clock speed stays steady, the frequency changes by about 200MHz in games that don't use AVX. Not sure if this is typical for Intel right now.
The Task Manager and other popular monitoring tools often provide inaccurate readings, leading you to believe your CPU is performing tasks it isn’t. When BCLK is measured accurately, the variation remains minimal, typically under +/- 0.0001 MHz. This issue isn’t due to Spread Spectrum problems but rather from subpar monitoring software misrepresenting CPU speed. If your CPU is configured properly, it should maintain a consistent performance level. In BIOS, I set BCLK to 100.00 MHz, and the system runs smoothly at that frequency. At standard settings, a 10900KF adjusts its speed between 4900 MHz and 5300 MHz based on active cores. Are you using default turbo settings? For stable readings, consider overclocking all cores consistently. In BIOS, set AVX Offset to 0, disable Thermal Velocity Boost throttling, and turn off V Max Stress throttling. Your CPU should not experience speed changes. If you’re using HWiNFO, observe the Effective Clock data during full load. Still noticing fluctuations? When the CPU is fully engaged, the Effective Clock usually stabilizes. Core clocks tend to vary unpredictably around 5000.0 MHz, but these swings aren’t reliable.
