Reduce energy use and heat generation without sacrificing speed. There are several approaches—adjusting voltage or using an offset strategy—and they can be implemented via software or BIOS settings. The main steps remain similar, though each method has its own advantages and drawbacks. Start with a reference of performance and temperature to define a stress test. Instability often appears as declining performance, so establishing a baseline is crucial. Cinebench serves the purpose well, but for more demanding tasks Y-Cruncher might offer better results.
Choosing a stress test is next. If you're lowering voltage, aim for extreme scenarios like Prime95 Small FFTs. These can trigger thermal throttling under default settings, making them less representative of real-world stability. For static voltage adjustments in BIOS, locate the VCore configuration, switch to static mode, and set it to 1.35V. Determine the CPU multiplier (53 for P cores, 42 for E cores), then configure the LLC setting to Mode 4.
If using the offset method in BIOS, change VCore to offset mode with a negative value of 0.01V. For software-based approaches, install Intel XTU and modify its voltage settings—either offset or static modes, targeting -0.01V or 1.35V respectively. In static mode, set the LLC setting to Mode 4.
After completing tests, run the benchmark and stress test for at least five minutes. Note the results to confirm stability and consistency. If performance degrades, lower the voltage incrementally and retest. For a thorough evaluation, perform a stress test lasting two hours or more. Monitor for crashes; if they occur, increase the voltage by 0.01V and continue testing.
Regarding differences between methods, software undervolting is faster since it avoids constant reboots, while BIOS undervolting works without requiring XTU to stay active all the time. It’s largely a matter of preference—static settings offer more reliability but higher idle power use, whereas offset settings provide better stability at the cost of slightly longer setup times.
Ideally, combine both strategies: handle most adjustments in software via XTU, then switch to BIOS for deeper tuning before finalizing. This hybrid approach leverages the strengths of each while minimizing their weaknesses.
The CPU system voltage and Vcore are related but not exactly the same thing. Vcore is a specific voltage value used in BIOS settings, while the system voltage can vary depending on your motherboard and configuration. I don’t see a direct match between the two in general. Regarding the LLC mode and CPU core details, those are advanced settings usually found in BIOS or through manufacturer tools—check your manual or visit the support site for step-by-step guidance.
The system agent refers to something different, like CPU core voltage. After selling my ASUS Z690 board, I can't recall the specific terms or locations. LLC settings will appear in one of the submenus. If you need help with screenshots, I can describe the menus and options, though I might not remember the exact names right now. I'll check for BIOS screenshots of similar boards to clarify the details.
You should place the CPU core values in the section labeled "vcore" or "llc" as specified in your configuration settings.
You can reduce the voltage if your setup remains steady at those current levels.
Adjust the VCore setting (VRM Core value) repeatedly until the system becomes unstable.
