CPU exceeds base frequency briefly for one second.
CPU exceeds base frequency briefly for one second.
My processor is an i3-1005g1 from a CRATOP. It’s causing overheating lately, so I tried lowering the voltage on ThrottleStop. Curiously, I ended up pushing it beyond its safe limits. Its top speed is 3.40 GHz, but it sometimes hits 3.43 or briefly reaches 3.5 before dropping back to 3.40. The jumps are unpredictable. Keeping an eye on performance isn’t easy since I can’t always check Task Manager and taking screenshots is tricky. Do you think this is due to a lucky silicon draw? What’s really going on here?
It's a locked CPU, the only way to exceed its max frequency is by increasing the BCLK. Most laptops typically run between 99.5 and 99.8 BCLK. Likely the issue is that your laptop jumps to 101 or 102 BCLK, which causes the frequency spikes. If the multiplier is 34 and you see a jump to 3.5, it probably means BCLK also jumps to 103. Download and install CPU-Z, then verify if BCLK exceeds 100. If not, the CPU might be jumping to 3.5 for another reason.
Sure, I'll take a look. If boosting the BCLK is possible, should I set a permanent BLACK setting? That would be awesome—especially for overclocking a locked CPU. Thermal performance shouldn't be an issue.
Share a screenshot of ThrottleStop displaying your CPU speed. The TaskManager isn't reliable. Processors relying heavily on turbo boost tend to show more issues.
