Here’s a revised version of your text:
Hello everyone,
Attached you’ll find a brief system overview: 12700KF Asus Prime Z690-A with 32GB G.Skill DDR5 RAM, Intel Arc A770 GPU, running Windows 11. I’ve been experimenting with overclocking to boost performance, and it seems I have a solid setup.
I managed to reach 4100MHz for the E-Cores and 5100MHz for the P-Cores without needing higher voltages. Using Intel Extreme Tuning helped keep the VCore below 1.35V during Cinebench Multi-Core tests. After converting the profile to ASUS Bios, I noticed the VCore would spike occasionally. Adjusting only the P-Core and E-Core multipliers had minimal impact; the rest stayed on Auto mode, except for the XMP settings.
To explore ASUS AI-Optimization, I overclocked the P-Core to 5100MHz and the E-Core to 3900MHz. However, during Cinebench rendering, my VCore and VID reached 1.519V—this happened only at the end of a run before restarting. Once stabilized, voltages settled around 1.282V or lower.
When I disabled ASUS AI-Optimization and manually overclocked, spikes dropped to 1.465V for VCore and 1.485V for VID. The fluctuations were noticeable when cores activated or paused. If you’re seeing similar spikes during Intel Extreme Tuning, it might be worth investigating further.
Could these brief surges be normal, or should I keep tweaking settings to minimize them? I want to ensure the CPU isn’t being stressed excessively.
Thanks!
You can significantly reduce your voltage by adjusting the clock settings in BIOS to offset mode—negative, 0.1—and it should bring you to around 1.25v load, which should work well.
It's been quite unusual. I've attempted all methods and still can't achieve a stable system with voltage under 1.4V. As mentioned earlier, with Intel Extreme Tuning, my VCore stays below 1.35V during Cinebench Multi-Core. After converting the profile to ASUS Bios, I began observing this VCore spike. Applying the offset keeps it near 1.35 or lower but causes crashes when running Cinebench. What's happening?
