How do i use Gigabyte's DVID to lock onto a certain voltage?

Hey guys, how are you? Need some help. After finding out what Gigabyte's DVID is, I wanted to make sure i'm doing this right so I don''t mess up and overvolt my CPU to it's untimley death. My i5 2500k can sit at 4.5GHz with a Vcore of 1.3v. The stock VCore is about 1.2v-1.212v. If i want to increase it to 1.3v, i'd input a DVID of 0.080v correct? Do I need to enable LLC whilst doing this, or will LLC be unavailable. I just want to know what other vcore options i can use, as LLC is undervolting and over volting waay to much, leading to system instabiility and un-needed voltage. Thank you!

Setting a manual Vcore is the only way I know to "lock" a certain voltage. DVID is used as an offset from the "NORMAL" voltage. This however sets an adaptive voltage instead of a fixed voltage.

I recommend setting LLC to HIGH, set CPU Vcore to NORMAL, and leave DVID at +0.000V to see what you get for a Vcore in CPU-Z or HWMonitor. I did this on my mobo I got a vocre of 1.308v , so I went back in an set DVID to -0.010V which gives me an ideal vcore of 1.284/1.296 in CPU-Z.

Oh - and after you make these changes and "save and exit" it will boot to windows. When windows loads - I recommend shutting down. Once shut down - boot up into windows. For what ever reason going from a fixed Vcore to NORMAL didn't work for me until the PC shut all the way down.

I have 1-10 levels of LLC, so it's just not descriptive or helpful in what each level effectively does unfortunately..

What motherboard? I would try a fixed 1.300V vcore and see what CPU-Z or HWMonitor reports for an actual Vcore both at idle and under stress testing. Then use progressively greater levels of LLC until you see the voltage maintaining (within 0.010V) between idle and stress testing. The purpose is to limit Vdroop without creating Vboost with LLC.

Once you know the best level of LLC, change your CPU vcore from 1.300V to NORMAL and leave DVID at +0.000 to see how vcore behaves. If you see that in NORMAL that Vcore is 1.280 but you need a Vcore of 1.300 for stability then set DVID to +0.020V. Again - monitor Vcore during stability testing.
