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....Quote:

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...
dude it's been said in the thread
read it :p :D
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 oneQuote:

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 beforeQuote:

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.
I'm sorry but are you certain of this? T_M has it in his post on the resistor just below yours found here, please explain, thanks...Quote:

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?Quote:

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.
OK, so I did this pencil mod and OMG its fooking awesome! Like, wow who would have thought something so simple could do so much?
before mod
1.5v set in bios. PC health in bios showed 1.44 CPU-Z showed 1.42 Under load 1.39v
after mod
1.5v set in bios. PC health in bios showed 1.48 CPU-Z showed 1.486 Under load 1.496
Holy crap!
Pic of it done on my 780i, may be a crappy pic, old camera, new one coming for xmas :D

Its amazing what a difference it makes. I just redid mine a day ago to play with my new e8400, stroked it about 4-5 times with #2 and mine overvolts a slight amount. Im not complaining though.
Worked on my 780i to an extent, bios set to 1.275 only showing 1.26 under load. Penciled the vdroop heavily, even tried to pencil both, but nothing changed so I erased the seond one.
OR is there something I need to do with the vcore? Do I pencil that too?>
I just read thru that, I am suppose to shade the vcore, arent I?
Anyone, lil help here, lol
Did you shade the whole thing?Quote:

Sorry to bump this old thread, but I have an XFX 780i and the Vcore drops by 0.088V under load. Will dins22's pencil mod do the trick for me? I am a bit confused by the Vcore mod, since it only shows one indicator and says "to ground", which I don't fully understand.
Also, can I use conductive ink instead of a pencil?
the point of using a pencil (graphite) is to be able to vary the resistance - conductive ink would be bad then since it would be a straight trace then (correct term?) so don't ever use trace ink when it calls for penciling to vary resistance
Thanks for the heads up. I guess I'll have to wait until tomorrow, since I only have HB pencils in the house.
I also found this article on Anandtech stating how bad modding the vdroop is... http://www.anandtech.com/cpuchipsets...spx?i=3184&p=5
What's about that?
It's quite simple:Quote:

If you try to eliminate the droop voltage in a circuit that was designed with droop in mind, odds are that the overall decoupling capacitance is too low to smoothen the voltage over-/undershoots on fast load changes. That means that you'll probably make your CPU suffer from these spikes (positive or negative), which again means that it probably won't live very long.
Yeah I understood that. I am using the CPU at Intels max specced voltage (1.36250V) with the pencil mod and have noticed that CPU-Z can go up to 1.368V when under load.
But as I have also stress tested the CPU at 1.5V, I'm pretty sure that minimal upwards tolerances like this are in a non critical area.
Yep the extra stress will most likely only show in the long run. But you never know. The best thing is to leave the droop function untouched unless one plans to do some additional modifications. Some of the newer boards might have more headroom and supposedly were designed so that one can "disable" the droop function. But that depends on the very board you're using. I dare to say that that all 680i based boards were probably still relying on the droop function in the design stage.Quote:

I'm still sitting with the issue of a 1.4V VTT max, as I cannot clock higher than 450mhz because of it. My goal was 500 at least... Is it possible that I need to re-flash the BIOS with the P08 CD from XFX again? Or even try P07?
I would be careful with statements like the one above. As long as you didn't design the board, who told you they were the same? Is the layer count the same? Are all voltage regulators, transistors, opamps and even the capacitance and inductance values the same? I highly doubt it.Quote:

You always need to double-/triple-/quadruple-check when it comes to hardware-mods.
Anyway, if you got the bios option, why not use it. I just saw that you actually had a 780i board and not a 680i, as I had thought first when looking at the threads topic.
thank you so much guys this very easy 2 sec pencil mod my qq600 evga 680i stable at 3600 ghz
