High core vid due to overclock
High core vid due to overclock
Hi! I'm running a 6700K at around 4600mhz with temps under 70°C under load. The core voltage is between 0.846v and 1.438v, which seems really high compared to what I expect. I've been doing this for several months without any issues. I tried overclocking using the motherboard BIOS self-overclock tool (Asus Z170 Sabertooth Mark 1), but I can't reach 4.6ghz. Maybe because I don't want the voltage to spike so high? Should I skip adding extra power just to keep things stable?
Your BIOS offers multiple options to customize your CPU, so understanding the distinction between VID voltage and Core voltage is important. If you don’t plan to overclock, keep it on Auto.
VID stands for Voltage Identification Digital, which Intel defines for your CPU within a certain VID range (http://en.wikipedia.org/wiki/Voltage...cation_Digital). This indicates the maximum voltage the motherboard’s VRM should provide to the CPU, with Vcore typically ranging between 0.846v and 1.438v based on system demand and speed.
You can manually adjust Vcore in BIOS for improved overclocking, but this approach may pose risks if auto settings are used. It's also important to remember that VID readings aren’t always precise through software tools.
Avoid setting the core voltage above 1.4V to ensure longer lifespan when using manual Vcore adjustments. VID values can also change with different Cstates, which overclockers usually disable because it impacts stability and isn’t ideal for custom settings. Additionally, Vdroop should be taken into account; correctly configured LLC (Load Line Calibration) helps achieve a more consistent overclock.

Understanding the distinction between VID voltage and core voltage is important for your CPU overclocking setup. Your BIOS offers multiple options for adjusting these values, but it’s essential to know their differences.
VID voltage refers to the specific range Intel sets for your CPU, as detailed on Wikipedia (http://en.wikipedia.org/wiki/Voltage...cation_Digital). This voltage should match the VRM's capability, which varies between 0.846v and 1.438v depending on system load and frequency.
You can manually adjust Vcore in BIOS for more precise control, though this may risk unstable overclocking and could be unsafe if not done carefully. It’s also important to remember that VID readings aren’t always reliable through software.
Exceeding the core voltage limit of 1.4V is not recommended for long-term stability. VDW (Voltage Drops) can also impact performance, so setting them correctly with LLC calibration helps maintain a steadier overclock.
Yes, I uploaded a photo earlier, but it seems to have disappeared. It’s likely because the load has decreased, which affects the peak readings. If you change the VID voltage yourself, you might see higher peaks than expected since the system isn’t under maximum stress.
