OMG, this was too easy. I even did it while my computer is running, and i can see the vcore increasing until it got so close .

I used this pencil for the mod:



I drew a line between the blue dots as you can see, and each time i make a line the vcore in CPUZ increases until i reached what i want.
PS: if your voltage went higher than want you want just rub it with your finger one time only.



Here are some pictures

Before Load

After Load

Happy OverClocking

VERY NICE.

I find it crazy how u said you did it with the computer running.
Can be dangerous. But w/e Nice Work!

GRRR I am using the same pencil, but I can't get it to work lol. something is wrong.

I am gonna have to do this mod and find out a way cause my vdroop is bad lol. got it set at 1.5 in bios, drops down to 1.47 idle than 1.45v under load :\

I dont get it >.>

GTT

try to make more than one line.
you didn't get what ?

Yeap tried lol it won't budge lol. It's like sitting there laughing at me and messing with my PSU lol.

I read the article from Intel and most of it flew right over my head, but from what i picked up, it sounds as though vDroop is designed to keep Voltages lower during idle? Probably not? :P

when i didnt do the pencile mod my Vcore would drop during load and cause it to not be stabe. i had to run at 1.3875 vcore just to be stable at 3.0 but after vdroop mod i can run at 1.375 vcore. all the vdroop does is keep your voltage from fluxuation (and in my case that is all it did)

Here's a quick and very rough explanation of how vDroop works (and why it does):

V = P / I, where V = voltage, P = power (in watts), and I = current.

Under normal operation, the powersupply and motherboard work together to keep the power delivery (wattage) the same.

Idle: 3 = 6/2
Load: 2 = 6/3

As you can see, the voltage drops because the current goes up (processor requests more current do to work under load). The vDroop mod is designed to reduce resistance on a particular resistor that delivers power. Less resistance, more power (in theory).

Idle: 3 = 6/2
Load: 3 = 9/3 (current goes up, but because of the vDroop mod, the power also increases due to less resistance).

That makes me wonder if CPU-Z reads the correct Voltage in the first place. My nVidia Monitor always reads the correct voltage that i have set in the bios. Example: My vCore at the moment is 1.35 in bios. nVidia monitor reads 1.35 but CPU-Z reads it a bit lower at 1.32. In my opinion not a huge difference, but hey, im new to this. I guess i might not fully comprehend if my motherboard is infact fluctuating or not. This could be the case x.o.

Maybe it's just one of those days.
