btw guys

i tried it on 780i and it works properly

1.8v in bios >> 1.8v in windows load and idle with a quad core yorkfield :D

So the way you have your red Line drawn in that pic is the way the pencil is suppose done....

Please if someone could confirm the pic and the redline..I would greatly appreciate...Getting my MM case and all my W/C and my 9650 today. Would like to do this mod now...Thanks

that's correct

Could someone take a pic of the internet of the 780i board and circle where the mod is suppose to go..Because the area that needs to be done is different than the 680i...Sorry but I dont want to do the wrong place...Iam already nervous going W/C...

So noone has a pic of thier board that has already done the mod and circle where iam suppose to do it at..

Ok if someone will take the time out of thier busy schedule and take a pic of thier board with the mod done on a 780i evga or xfx and circle where the mark is suppose to be i will give you a 2g ddr2 800 Supertalent stick of memory...

There has been no pics posted with the mod done on the 780i mobo. only the 680i And from what I can tell they are not positioned exactly the same. So I just what be double sure iam doing the right one

thanks anyway..After looking at the pics..Blown up on the 680i and the xfx 780i the scratch places are in the exact same place..not sure what I was looking at before

I just did this mod and it works great for evga 680i sli!! Thanks!!!

Where do you pencil for the vCore mod? Across the resistor? It shows one side of the resistor going to ground, is this only a hard mod??

Tried Dinos22 mod on my Evga 780i

Works like a charm :D

Before mod

Bios 1.4750v
idle 1.42v
load 1.40v

After mod

Bios 1.4000v
idle 1.38v
load 1.39v

Cpu is still 46 idle and 70 under load

System

Evga 780i SLI A1
Intel C2D E8400
4x1GB OCZ SOE PC7200

I think I may have to try this :)

what are the vcore and vdimm voltage read points on the 680i motherboards?

bookmarked for use when i get home

thanks.

Ruckus, I just did the vdroop on the same XFX board with good results. With Core set to 1.5v in BIOS:
IDLE LOAD
Before: 1.464 1.440
After: 1.480 1.480

It got the voltage closer to what its set to, and completely stabilized it under load. I'm about to start working up an overclock. With a Q6600 on a 680i board I know that I'll likely be limited, but going to do the best that I can.

they both do the job

i just found the other one more reliable in my testing :up:

Sorry, newcomer here. I tried this mod, but I set 1.3 in BIOS, but it reads 1.264 in Windows on load. Did I do something wrong? I used a 2B pencil and did a couple passes over the resistors.

I thought you could put electrical tape over a pencil mod so it wouldn't wear off too... anyone got an answer to this?

hmm... the p-mod only raises Vcore a bit, but then still drops .03 under load.

worked on my XFX 780i. gunna take some 5-min epoxy home to make it permanant.

My board's voltage would normally drop about 0.05v from where I set it and 0.675 when under load. I did the pencil mod on the blue points very heavily because it wasn't showing at all after about 10 traces.

I'm now at the point where if I set the voltage to 1.25v it reads at 1.23 in the BIOS and 1.232 in CPU-Z at idle and under load. It's still below the BIOS setting but doesn't variate at all anymore. Basically what I'm asking is will it be safe to take the resistance all the way up to where if I set it to 1.4 in the BIOS it stays at 1.4 at idle and under load?

I just wonder if it's safe for there to be no variation in the voltages when under load. Thanks.
