Ok some update from me ;)
Vga with water and done vgpu with 1k VR Start testing for max vgpu and hmm not bad 1.55V is ok. More V = kick from OVP :p:
Already hit 620FPS in nature 01 with clocks 675/999MHz and cpu @ 3850MHz
Temp not good 65C stress :mad:

I'm using 1.35V idle (1.31V load) 24/7. Card is watercooled.
I think that totally safe values are ~1.35Vgpu and ~1.95V to memory.
Of course you can use higher volts, but there is no way to estimate is it safe.
Any new ideas on the "wall" at 700MHz core? Is it temperature related, or is there more to it than that? My card is loading at 36-38 degrees and I think I should be able to do better than 685-690Core.
My VCore reading is still weird...DMM(s) measure VDDR accurately, and probes show that my core Vmod works so i`m in the right place, but still reads about 0.1V higher than everyone else...weird.
Yesterday i was finally able to fire up my modded 8800gts.
default:
1.26VGPU (load)
1.90Vmem (load)
648/1000 max. stable for 24/7 gaming
modded:
1.40VGPU
2.02Vmem
720/1035 max. 24/7 stable =)
mem oc improved only a little bit but its fine, i can go even higher for benches and still raise vmem a little.

Stock:
idle 1,305 V

€: its a Sparkle GTS
I have tryed the mod but it dont works, I must try it another time
I will test my GTS with dry ice soon. So then we will know is it only temperature related problem.Quote:

*what my DMM says...might actually be 1.32-1.36V?
What kind of gpu temperature did you got with dry ice? (with bad contact)
My lowest temp has been with chilled water (17 celsius idle ~25 load)
ROFL 0 to +15 degrees...when I say bad I really mean ******* awful :D
Under the chiller i`m loading at 34-36 degrees. I can take it lower, but none of my gears insulated at the mo.
Your major HWBot competition wont be coming from me at the mo, put it that way ;)
EDIT: pushed a bit harder and can bench 3D03 at 735MHz core, at 36 ish degrees with my DMM showing 1.52V load....that might be 1.42-.146V compared to everyone elses, which seems more in line?
Users with 320MB versions of GTS, please post idle/load voltages here and tell us how Vmod's are working. Thanks!
will do,they just came forsale yesterday in states .getting two and i will help you help me. thursday they will be here.
thanks for all the info

I havent tried vmodding before and there is something i dont understand.
When i compare the pics of the mod done on your card and the picture of how to do the mod then the wires are not soldered to the same places, Why is that?
Where excactly do i solder the wires to?

Gonna give the core vMod a shot here soon.. Do you guys think I may get some pretty decent results? My core is 24/7 stable at 684 under water, and I can bench at 702 as is. I was thinking that an extra .1V may get me into the low to mid 700's for benching.

Oh yea, I took some reading's before I started messing around.

For the core mod in the article i linked. how can I calculate the vcore it will give me with a given resistance? reason i ask is the 500ohms VR i got is reading only 425ohms when testing with a multimeter. (Yes its turned all the way). i need to know if I stick this 425ohms on it what vcore I'll be at?
cheers
Anymore vMem pencil mod success cases ?
Memory temps after the mod are mutch higher ? (don't think if there is an easy way to know that but ... :D )
FYI, in my case, I upped the voltage to 2V and only got another 17MHZ of usable clocks.Quote:

I am going to stick with 1.96v on the mem, and teh 1107MHZ.. treating me good.:D
I am about to order the trimming pot for the core voltage soon. Pretty excited to see how it does..:banana:

Dinos22, what we do here is use conductive paint as a 'solder'. So I mask out the area with insulation tape, in this case the one side of the resistor, tape a single core wire (if possible, not necessary) up to the resistor so that it just touches, think put a tiny blob of the conductive paint (must be the adhesive kind). And that takes the place of soldering. When you are done clean up with acetone. I can post an image if you like?Quote:

I use an earbud, dip into acetone & clean specific area, normally only a few pinheads big. Am I about to get a lesson in why not to use acetone on a PCB? :pQuote:

acetone eats through PCB and exposes traces lol but i guess if small amount maybe it ain't an issue donno

The windscreen repair kit type paint will bleed under the insulation & cause problems. Not sure about the pen, have never tried one before... So test it first.
Hope that helps :D
pls confirm that you are basically connecting the two poles of that resistor that's insulated with conductive material right?
you could also use a 2B pencil for that i reckon hey
No, I'm not explaining myself well...Quote:

The image does not show the masking.
http://i60.photobucket.com/albums/h10/TraXzor/wire.png
oh i see now
instead of soldering you are simply "gluing" the wire to resistor so to speak :)
looks like a lot of work mate :D
Yes, not as quick as I would have hoped for. It took me around an hour to do vgpu, vddr & a read point for each. Not sure how long soldering takes, I don't have a soldering iron & have no soldering skills. So this method is great for me :) ...and as you asked, it is not permanent ;)Quote:

Between this red spot and ground I measure 469 ohms. I tried with 2 different multimeters, so it has to be accurate.
So if I wan't to vmod it I'll need a 5k or 10k trimmer ?
Card is Gainward 8800GTS 640MB
try a 500ohm 15-18 turn vr or a 1kvr set at 490-500ish to start.
just for heads up on my evga 88gts320sc 240ohms is about 1.40 at load
may be differant on different cards depending on stock core volts thuo.
Any chance of a vgpu pencil mod ?
Soldered a 10k multiturn VR, works flawless. :)Quote:

Yes, there is indeed a large voltage drop on the GPU core power regulator.
Dinos, the MCW-60 rocks on GTS cards, I'm able to beat my GTS stock cooling with more then 30°C on load (fan auto) :D
There is no other VGA waterblock who can touch this kind of performance ;)
What temp are you getting @ load?
My EK fullcover keeps it at 46 max :)
Beneath 40's, even with pump at 7V.
In the Madshrimps link you showed above we can read this on last page:
Guess we'll find out very soon what is hot and what is not :DQuote:

Danger Den NV-88GTS-PC & NV-88GTX-PC: full cover waterblock

Keep an eye on our website as Madshrimps is about to review each of those 8800 compatible heatsinks.
Am I correct in thinking that for the vgpu mod in the madshrimps article. You just connect the VR between the red point to any ground? This point looks easier to solder than the one in this thread. :)
By any ground I mean, can I use a pin on the power conector as ground and not the pink spot. As the pint spot looks alot harder to solder (more chance of a short).??
EDIT: or is it the red point that is the ground? :(
It's well explained in the picture:
VGPU mod for reference 8800GTS. Pencil resistor marked in blue or solder a VR between red and pink. The pink point is the one you always have to use, red is ground meaning that you can connect your VR to a black PSU power cable instead of the red point.
OK thanks for clearing that up.
hey guys i want to ask a question bout the vr... which pin do i solder to ground? the middle one or the sides? or it doesnt matter?
Don't think it matters as long as you use the middle for one and either one of the outside ones for the other point.Quote:

Just done the GPU mod on both my GTS's cards.
Resistances are fine. Voltages are up to 1.35 without turning the resitor down and the cards still boot.
GREAT!
Waiting for glue to dry to stick the resistor to the board before i play with it to much (so i don't accidently move the resistor and pull the solder).
Next up is a pencil mod on the memory.
should i be worried about the left over flux on the board or is it harmless?
Thanks
Richard
Sorry to ask such a n00b question, but every other vmod i've done I've used non variable resistors (which i would still prefer to do). But after I do the Vmod i crank the resistance all the way to the highest value before powering the card up, correct?
Yeah put it to max.Quote:

I'm already doing 660/2100 stock cooler/voltage on my Leadtek 8800gts. What gains could I expect from the vmod providing I'm cooling the card well. I haven't soldered before and I would like to learn more and get a soldering kit but I dont really know where to start. If anyone can help me I would appreciate it.
You might want to try your soldering skills on lower-end (and cheaper) hardware. 20W soldering iron should be ok, make shure you get one with a fine tip. The vmod on the GTS won't get you much further because of the safety precautions in the voltage regulator.Quote:

So i removed the wires to read point, installed stock cooling and all seems fine now. Very wierd.
It is a shame to as it took me forever to get my hand steady enough to make the Vgpu solder. I really don't know how you people can do it. That point is way to small.
I see on that madshrimp site it shows a pencil mode for Vgpu, anyone try it out?
Just did this mod on my 320mb today .
Where does the OVP kick in @ .
What Vgpu and Vmem are most ppl Using
Right now im @ 1.5v gpu and 1.96v mem
675/1060
680 or 1065 wil cause it to lock up
Im on stock cooling BTW next friday I will be getting a WB for the card .
ovp kicks in for me anyway after @1.429 read in 3d mode,good for 700 ish
stock cooling,reseated the heatsink with as 5 and ghetto mod to fan.
same 1.4289 with some dry ice to cool ambient temps 730 ish
for stock heatsink 1.35 @load is hot to say the least,well depends if its summer or winter where you are.
but for benches i turn volts up,gamein or desktop i just turn it down.
How can you tell if ovp kicks in or not?
Is there a way to disable ovp on these cards?
SAD
did you use 1kohm vr?even a 1k "set" to 800ohms only gave me 1.31 at load if i remember correctlyQuote:

I can't go much higher on my card than before. I don't have a multimeter on me so I can't really see how much extra voltage I have tho.
Before pencil mod I could do 690 on the core and now I can do 700. As for the ram....
well the ram could do 1700 before the mod and is still completely stuck at 1700.
I also have recently changed from stock cooling to a HR-03 PLUS and it hasn't made any difference on the OC but its obviously helped the temps.
I'm considering doing the solder mod next weekend.

1st thing should I measure the stock vgpu?
then I'm suppose to measure the resistance of the pink and red points with the card unplugged.
Then not enough resistance so start soldering?
I'm nervous. :\
how do you guys stick the vr to the corner of the pcb so neatly? Is that a glue gun? Any good place to order extra vr's online if you live in US? Thanks :)
Quote:
For the GPU core voltage mod we must search for the Primarion PX3540 PWM IC. The resistor marked in blue is the one you need to shade with your B2 pencil. Strike it a few times and measure how the resistance changed, you can check resistance by holding the red wire of your multimeter to the red point and the black wire of your multimeter to the pink point.
The stock resistance measures around 35 Ohm, this is very low and this will make it very hard to pencil mod the GPU core voltage, we recommend doing the soldered modification. For the solder mod we used a 1kOhm adjustable resistor (often called VR) and soldered it between the red and pink point. This changed our stock voltage from 1.3V to 1.33V. To further increase voltage we must lower the resistance of the variable resistor, before you power on your system always make sure that your VR is set to highest value. For 1,4V we adjusted the stock resistance of 35 Ohm to 29 Ohm.
I used 20k VR for both the Vmem and Vgpu . I should have used a smaller VR for the Vgpu But I just turn it very slow and i can still dial in what im looking for .
So other ppl over 1.45ish get a black screen from OVP ? i have had mine upto 1.65v and it was still working .
Im hoping to get into the 700mhz range when I get it on water

Really ? you can run @ 700 on air with only 1.42v ! the best i can do is 676 and that is with a 92mm Tornado on the HSF .
yes @1.428 120mm fan bolted on stock heatsink 700 @65f room temp
and Lord RTKK(really great job bro) runs 890 @1.59 it shows that its in the cooling i think

more volts is not always better...... nah nevermind it is lol
i Have 1.23 IDLE and it goes to 1.21v load on my EVGA. Max clock is 636 Core any more it crashes on STOCK cooling.

hey guys, im contemplating doing a vmem pencil mod, but im not exactly sure how to do this.. Ive never done a pencil mod before but I'd like to give this a go as I can only reach ~870 stable on mem whereas im reaching 685 so far on the core stock volts. I read the madshrimps vmod guide and they say to just strike the resistor a few times... So i just run a few lines across the resistor and then measure using the 2 points listed? Does the card need to be in the system when I measure these points or not? Sorry for such a noob question.
wow! 685 gpu is pretty sweet with no mods. very nice core on that card..
I agree your mem clock needs some work.
hey guys, which voltage is safe for 24/7 use?
i tried 1.38v vGPU (Load / idle ~1.42v)
