Discussion on Vcore and LLC for my 8700k
Discussion on Vcore and LLC for my 8700k
As per the title, you're seeking advice about your Vcore and LLC settings. Your specifications include an i7 8700k with Thermal Grizzly Conductonaut, a Gigabyte Aorus Z390 Ultra, a Cyrorig A40 Ultimate 240mmX38mm radiator, and other components with copper heatsinks. You're experiencing stability issues at 5ghz overclocking and are concerned about Vcore and LLC voltages.
I don't believe you fully grasp how or what HOW LLC operates.
LLC or Load-Line-Calibration aims to enhance voltage stability during sudden changes in CPU load.
For instance, without LLC, if your CPU runs at 1.35v while you execute a program like prime95, the vcore might drop sharply—potentially to around 1.22v—which could lead to system crashes.
With LLC, it corrects this problem. When properly configured, it keeps the vcore steady near 1.35v with minimal fluctuation.
However, if you raise the LLC settings excessively, you risk triggering vBoost, where the voltage is overcompensated beyond need.
Therefore, you should reduce the LLC setting until...
I don't believe you fully grasp how or what HOW LLC operates.
LLC or Load-Line-Calibration aims to fine-tune voltage during sudden changes in CPU load.
For instance, without LLC, if your CPU is running at 1.35v and you execute a program like prime95, the vcore might drop sharply to around 1.22v, potentially leading to a crash.
With LLC, it resolves this problem when properly configured, keeping the vcore stable with minimal variation.
However, if you set the LLC too high, it can cause overcompensation known as vBoost, making the voltage application excessive.
Therefore, adjust your LLC settings so that you consistently maintain 1.3v or very near it under all conditions.
EDIT: I didn't notice you're stable at 1.3v, are you? Try 1.35v with a lower LLC and check if it functions.
