I currently have a 2500k and I have a question about setting the vcore in the bios. I have a MSI Z68A GD65 G3 motherboard and currently whatever voltage I set in the bios the real voltage at idle is about 0.04v less. Ex 1.46v set in bios and 1.42 seen in CPUID on idle and around 1.36 during load with 100% LLC which I know is from vdroop. My main question is, the magical 1.4v threshold for this chip, is that the voltage that should be set in the bios, the desired idle voltage, or the desired load voltage? What I want to know is if I should increase the voltage in the bios beyond my desired value to offset and achieve my intended value. My board doesn't support using offsets just manual voltage control
so I've been running some tests and last observations are with a vcore of 1.49v set in the bios i have an idle of 1.44v in windows which drops down to 1.344 during IBT and 1.360 during prime all with "Vdroop Offset Control" set to 100% (lower % = more Vdroop) I'm using a x45 mutil to set my clocks to 4.5GHz but I still cant get stable, I adjusted I/O voltage and PLL to where I now only get a x0101 BSOD. The system was stable through IBT and about 30 minutes of prime but did not last overnight. I don't know how long it lasted since I was sleeping and woke up to it off. I have a WC loop so during testing my temps never exceeded 72C. I find my Vdroop a bit extreme and feel like it's causing my instability , this is with all power saving features disabled
