I7 7700K OC issues Need help with overheating or performance problems?
I've got your setup with an RTX 3070, i7 7700k, H115i cooler and 1440p display. You're looking to fine-tune your CPU voltage to potentially avoid bottlenecks. Currently you're using Asus MCE with a 1.25V setting for turbo boost at 4.5GHz. You're considering adjusting it to 1.25V for a target of 4.8GHz and wondering if manual voltage control is more reliable than Asus's automatic approach, which might push higher voltages. Regarding Load Line Calibration, it's best to keep it on auto unless you're certain about your needs.
Generally, setting vcore to 1.25v achieves the desired performance. Adjusting the load line calibration helps avoid voltage drops when using a CPU load, which can lead to instability. Auto mode is usually acceptable. For my 6600k at 4.7GHz with 1.3v, raising the calibration improved stability (though this could depend on higher voltage settings). If unsure, stick with auto and aim for 4.8GHz. If instability persists, boost voltage or increase load line calibration.
It's important to adjust the offset so it reduces during idle mode.
Temperatures rise regardless of voltage levels, but they'll be greater than when running at lower voltages during idle. Overall power usage will increase too. For each CPU I've adjusted overclocking settings (like Ryzen 3000 and above), I simply fix the voltage and skip managing offsets.
To achieve low temperatures during idle, activate the core C states in the BIOS. Once a core reaches the C7 state, its voltage drops to zero. That’s impressive. During idle, you can enjoy a swift CPU operating at high voltage while maintaining minimal power use and stable temperatures. Intel’s C states are exceptional. Those worried about voltage or heat should definitely enable them. The screenshot illustrates that most cores remain in the low-power C7 state over 99% of their time. No concerns about power draw or idle temps, even with 10 cores running at 5000 MHz.
Yes, it’s typically found under the Intel power management settings in the BIOS. It’s usually configured to auto, meaning it should be active by default.
