Assistance with reducing voltage settings.
Assistance with reducing voltage settings.
Frank Cisco, adjust the core and cache voltage to lower levels. Begin conservatively. Perform tests at -100 mV or -75 mV for both. Execute the TS Bench 960M check. This initial assessment helps verify stability. Any errors indicate the CPU requires higher voltage.
You're following the guidance carefully. Once stability is confirmed, you'll continue reducing voltage by -5 each time or by -1 until the process stops. After reaching a stable point, you'll retain the previous value. You're following the instructions clearly, which is great since you're new to this. Thanks for your support!
During initial stability checks, I usually change the voltage in larger increments such as 25 mV. Adjusting just 1 mV at a time would take a long time. When errors appear at -100 mV, I should revert to -75 mV. If everything seems fine, I can try around -85 mV. Once stable, it’s a good idea to test in the middle, like -85 mV. There’s no strict science involved—just aim for consistent performance. Keep the voltage stable for a few days to avoid random crashes or blue screens, especially when the CPU is lightly loaded. Many users notice fewer crashes during normal use if they don’t push the system to its limits. Avoid chasing an exact voltage; small adjustments are better. If you’re not stable at -100 mV, consider adding at least 5 mV and possibly 10 mV. An offset of -90 mV could work as a middle ground. What voltage are you working with? Are you noticing any performance gains or temperature changes from undervolting? If your system runs smoothly at full speed in Cinebench with the default setting, undervolting won’t speed it up much—it might just make it cooler. 8700K processors can be overclocked, so many people prefer this approach over undervolting. What’s your main objective?
I aim for reduced temperatures while maintaining performance through voltage adjustment. My CPU is quite old, so I'm focusing on upgrading my GPU to an Asus ROG RX 3070. The goal is to lower temps, keep performance stable, and extend the CPU's life for future upgrades. I also noticed that in my area temperatures often exceed 32°C, even with a Corsair H110i AIO and a GPU that can reach 70-75°C after six hours of use. I spend my home office from 9 AM to 7 PM, working and gaming on this machine. That's why I'm trying to undervolt it.
You appreciated the guidance, I successfully used Intel XTU after adjusting what you mentioned. I ran several benchmarks and now I have my main question: how can I confirm my settings are actually working? I notice the core voltage offset is -0.170v. After playing TLOU for 30 minutes and using the PC for seven hours, there were no crashes. My power plan is now set to balanced, as I switched from max performance. Here’s a screenshot for reference. Thanks!
Thanks for the message. If you require a particular screenshot, let me know where to locate that option, and I’ll help.
Search HWiNFO for the Voltage Offsets part. Verify your XTU voltages are correctly set and activated during startup, resume from sleep or hibernate.
Yes, I notice them after starting up and resuming from sleep. However, they appear only in two out of the five highlighted sections.
