i7 13700 kf - überladene Spannung Probleme mit der Spannungseinstellung?
You're looking to lower your CPU voltage for better performance and cooler temperatures. Based on the BIOS settings you shared, you're currently using a performance profile with P cores at 5400MHz and E cores at 4400MHz. To undervolt, you can switch to a normal Vcore mode first, then experiment with a negative dynamic voltage (DVID) value. The DVID setting should be adjusted to a positive value if you want to undervolt effectively—this helps maintain stability while reducing heat. Always refer to the Gigabyte manual for specific guidance on safe voltage adjustments.
In general, there are two approaches to undervolting an Intel CPU: adjusting the VID offset and applying a static all-core overclock. Each has advantages and disadvantages. Most often I prefer the static method because it’s more stable and simpler for thorough testing. If you choose the VID method, setting a negative offset and verifying stability with tools like XTU, OCCT, or Prime95 is the right path. A value around -0.1V tends to be too harsh and could lead to instability; smaller steps—like 0.025mV—are usually safer, depending on your CPU model. Also keep an eye on performance metrics, since clock speed can drop unexpectedly after undervolting. This technique may cause clock stretching, where speeds stay high but performance drops, so a benchmark like Cinebench is essential before and after.
For the static approach, it’s a bit more complex but similar to older OC methods. Begin by adjusting the LLC settings in the VRM configuration—usually pick a steep setting from the graph. Then change the VCore voltage mode to override, aiming for around 1.44V with an appropriate VDroop value. Finally, fine-tune the multipliers for P cores, E cores, and rings (e.g., 5.3, 4.2, 4.7GHz). Launch a stress test in Windows, use HWInfo to track VDroop during the run, and gradually reduce the offset until stability is confirmed. This method uses more power at idle, but it tends to be more dependable since it’s less reliant on the CPU’s VID handling.
I attempted to lower the voltage using the DVID technique with a -0.05 V offset, which worked initially. However, the CPU still throttles and hits 100°C during Cinebench R23 multicore testing. Should I remove the OC settings for E cores at 4400 MHz and P cores at 5400 MHz?
Which cooler are you using? Running at a high load with R23 might exceed its capacity, especially if you're not overclocking it. It shouldn't be reaching such temperatures in this setup.
Check stability with 1.2v ball speed and observe temperature changes; many users report Raptor Lake CPUs remain stable at standard clocks from 1.1 to 1.2v.
You can adjust the stable value by modifying the BIOS settings, specifically the VCore offset. This allows you to fine-tune the voltage without changing the default core voltage. The manual explains how to locate and apply this setting in your motherboard's BIOS.
Single pass ensures the process runs once without looping, similar to shorter tests. Reaching 100°C is appropriate for extended testing, but ideally it should stop near 90°C for a single attempt. The board supports static voltage modes, though you might just apply a -50mV offset if that's the only option available.
