Makes sense, I figured it was a ground but wasn't 100%.
It is definately covered, card is a BFG OC. I'll just run it to another ground for the time being

aicjofs,
My card looks exactly like the one pictured here
You can see the white dots there pretty clearly. Where would be another "easy" ground location...without scraping off a "dot"...is there one?
Can I just run the wire to the back of the slot (were the DVI connectors mount), or maybe even the waterblock bolts comming through the card

instead of a conductive pen, is it possible to use a pencil instead? like a HB or 6B
Ok, just finished the mod, worked like a charm! 1.40v right on the dot. Currently working to find the max clocksOriginally Posted by Codeman05
Edit/Update
Wow! At stock 1.2v I maxed the core at about 550mhz...at 1.4v, I am stable a 675mhz @ 42c Load
Picked up about another 2,000 points in 3dmark03. I'll run 05 & 06 tomorrow, time to call it a night hehe

OMG insanity! Where can I find some of this conductive paint. Also is their some kind of solution to remove the conductive paint if we needed to or is it a permanent thing? Also, does the paint pen work kind of like a ink fountain pen that you press down to make the ink come out?

alcohol or acetone will remove it.. havent tried alcohol, but I think it works.
Conductive ink can be found at "car accessory shops".. It's commonly used to repair the heat-wires in the rearwindows of cars.
"Also, does the paint pen work kind of like a ink fountain pen that you press down to make the ink come out?" Does not compute. You mean the white stuff for correcting errors, then no.

I was meaning like the caligraphy pen's that have the paint inside.....sorry for bad grammar.

That might also be at sweet mod

pencil is not reliable , not easy to put down, and doesnt hold in place. Look around at all the solder pads areound the area.. a little bit of graphite accidentally left behind and you can easily short-circuit something.Originally Posted by kite7
If you cant solder, conductive paint, like defrost kit, is definetely MUCH better.. at very least you can see exactly where it went, and it will stick in place. You've already bought a $300 card.. you dont want to come back here complaining its broken because you were too lazy to spend another $3-5.

If you look even I went overboard with too much paint. It doesn't get much simpler but I can't stress enough how little paint is required. Don't dip the needle just a barely visible amount on the tip.

7900GT 1.4V Vgpu.

Difficulty: easy <- confused?.. this one is for you.
Tools: Car defrost kit, tape (to mask out where the ink goes)

Done by: cronic, aicjofs
Difficulty: medium
Tools: Car defrost kit, needle, (and very steady hand)
*aicjof has 7900GTX, and since this mod does +0.15V, that brings it up to 1.55V.

7900GT/7900GTX 1.2V - 1.55V / 1.4V - 1.7V variable Vgpu
Done by: SF3D
Difficulty: hard
Tools: very fine tip soldering iron, wire, DIP switch, connect it to points A, B, C (or use D508 and D511 as shown above) and ground.
Picture of dip switch->Attachment 45187
NOTE: do only one of these mods. For 7900GTX owners, point A (pin 21) is already grounded... the first listed variation (7900GT 1.4V) wont do anything.
EDIT: please stop asking questions when all the answers are there.

off topic. does your bfg-oc come with a special aftermarket cooler or just the normal one?Originally Posted by Codeman05
Farking awesome work Guys , thanks to all who worked it out , ill be doing both my cards when they arrive

according to this pic http://resources.vr-zone.com/Shamino/79mmod2.jpg Pin 30 = "B" in the pictures = D508 right padOriginally Posted by aicjofs
which one is correct?

Someone break out the DMM and check continuity...
The "right" pad. Picture is correct. Sorry for the confusion. I was trying to say just look at the connections in the picture, I should have not said a left or right at all. I was meaning the next pad to the left of d511 "in the picture" didn't come out sounding good at all. I typed that wording really bad.
It's why a picture is worth a 1,000 words. Always look at the pictures, words can be easily mistyped, misinterupted, etc

So could you do both the d508 to ground and the d511 to ground and get 1.5v without changing any resistors or anything?

Here´s my 7900GT with 1.55V mod
it´s modded with conductive paint that i got laying around since the old athlon xp unlocking days
well i let the pictures do the talking
+0.2V

So nobody found where pin 31 is located at the edge of the card among D511 and D508? I'll hopefully be getting my eVGA 7900GT this week and will be watercooling it... and I will also find a dipswitch to hook everything up to... Very nice solution, so getting 1.55v this very easy way would be very nice (and of course with the dipswitch from 1.3 to 1.55 in 0.05 increments ;-)
Pin 21 = "A" in the pictures = D511 left pad in the pictures
Pin 30 = "B" in the pictures = D508 left pad in the pictures
Pin 31 = "C" in the pictures = ??? (didn't look)
Yes, with D511 (pin 21) and D508 (pin 30) to ground you get 1.50V. Check the tables.Originally Posted by Fhqwhgads6680

usually, added voltage has diminishing returns. Since you are quite high at 1.5V, perhaps you are also hitting overcurrent protection.. For most people (those using air or water), I think 1.35-1.45V is the sweet spot.
Ofcourse if you have dry ice or phase-change, go ahead and try to beat LardArse with 1.7V+.

Trying to get a clear idea of how I should apply this mod. I would like a simple 1.4v for my GPU. Is there a way of applying the .2v mod without permanent implications?
