High idle clocks and voltage readings
High idle clocks and voltage readings
Hi everyone, I'm facing a challenge with my BIOS configuration and need some guidance. The settings are set as follows: Multicore Enhancement - Auto Ratio: Sync All Cores (48 for 4.8GHz CPU), VCore: 1.250. I've checked Intel Speedstep in BIOS, tried the balanced Windows power plan, adjusted the minimum processor power state to 10% under High Performance, and even reset all CPU settings back to defaults. Despite these attempts, my CPU remains at 4800MHz with VCore at 1.249, and none of the cores are reducing their frequency while idle. I've also tried switching Ratio to AUTO, but it didn't help. Firefox is open, using only 4% CPU, and CPU-Z confirms everything looks normal. Any suggestions or advice would be greatly appreciated. Thanks!
Disable multicore boost from auto to truly off and recheck the same configuration. You may need to adjust the AUTO ratio instead of using a fixed value. Keeping MCE on Auto lets the motherboard decide, but since they aim for top performance, it’s likely still set to auto.
Motherboards managing stock configurations can be frustrating. Without being able to inspect your BIOS directly, I can't give precise guidance. You've likely adjusted most settings already—perhaps a full motherboard reset would help restore things to normal. Once reset, you can review options such as C1E and power-saving features again. Could you share your motherboard model? That way someone with a similar setup can offer better advice.
On auto startup, an i9 10900k without AVX offset can execute Cinebench at 4.9GHz across all cores. When the ratio is set to auto, each core will independently increase to 5.1GHz, while 2 cores will reach 5.3GHz if the CPU is under 70°C. I believe you'll perform better with stock settings and XMP enabled rather than the current configuration.
The optimal method for lowering power use or idle load is activating C states. When core C7 is turned on, the overall performance of the rest of the CPU remains largely unaffected. In a recent test I adjusted the clock speed considerably; wall power usage fell from 52W to 50W. This shows little impact from slowing down a desktop processor. There was no notable change in power draw or idle temperatures. A swift CPU doesn’t need to run hot when it’s not active. What tools are you using to track this? The initial sections of Task Manager display CPU Utilization, which differs from actual usage. The 10900K consumes a large share of turbo boost relative to its base speed, making Task Manager’s utilization numbers unreliable. Check the Details tab for more accurate insights. The chip offers 20 threads; if one thread runs at full capacity (100%), it represents just 5% CPU load. Even a modest 4% load can keep a single core nearly busy, ensuring the processor stays active most of the time. All cores operate under the same scaling factor, so the CPU maintains near-maximum speed at least 80% of the time. Intel builds CPUs to run at peak efficiency whenever possible. This approach yields better performance per watt than running at lower speeds. For deeper understanding, refer to the paper “Power Optimization – a Reality Check.” If you wish for precise monitoring, try ThrottleStop, which employs high-performance timers and Intel’s recommended tracking method. It accurately reflects CPU scaling behavior. CPU-Z also shows consistent speeds regardless of whether cores are locked near 800 MHz or not, unlike some other tools.
