Glad, atleast someone replied
So can u tell me that, if i set a custom vcore, then will it stick to that voltage under all load conditions.....? Actually I own this system from 2 years, and i bought it mainly for OC, but due to too high ambient temperature of my city, the system runs hot, so since then i am actually hunting away to get only 4.0ghz stable OC. So long story short, Im a type of noob, and whenever I share this prob, everyone just throws loads of links to tutorials which always disappoint me.....
That setting for VCore voltage, it can be "Auto", "Normal" or an actual voltage number. If you type in a number for vcore voltage, it will always run at that voltage. That's called "fixed voltage" usually.
What you will want to use is "Normal" for vcore. You go to the vcore voltage setting and type "n" and hit Enter. The setting will then show "Normal". This is the voltage the CPU thinks it wants. It can message that number to the outside. This voltage will change all the time for power saving. In monitoring programs, it is called "VID".
To get stability when overclocking, there is a separate offset voltage you can set. This offset voltage will get added to the normal voltage. This is why that style of overclocking is called "offset voltage" usually.
The offset voltage setting is directly beneath the vcore setting in the menu. It is grayed out by default. It will light up when you set vcore to "Normal". The setting is named "DVID" on Gigabyte boards.
About "LLC" and why you have to change it: the board will drop the voltage somewhat under heavy CPU use by default, as that's how it's supposed to work according to Intel's specification. You should disable or reduce that voltage drop to avoid headaches regarding stability when overclocking. To do this, you go into the "3d power" menu and look for the "vcore load line calibration" entry. Put this on "Turbo" for zero drop of voltage under load.
If you use fixed voltage, you should use LLC on "Turbo". If you use offset voltage, you can also try Low, Medium or High. LLC changes the voltage depending on power use. That's exactly when the CPU is the hottest. So if you can't find stability without increasing offset voltage, you can try to reduce max temperatures through going down from "Turbo".
