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
SwifTech MCW60 + MC8800 SMC cooling Kit: G80 waterblock + passive heatsinks for memory/mosfet/NVIO
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:

ohh ok.... well the vrs that i bought look like this.... is there a major difference?

i dont really get wat u mean... um, does that mean i use pins two and three only? like pin three to ground?
No picture lol.Quote:

Using pins 2 and 3 will get you that. If you use pins 1 and 2 (you always use pin 2 which is the movable wiper in the pot) the adjustment will be backwards.

I so need to get my GTSs vmodded, I think I could just maybe get close to 18-19K on 06...........hehehe, well I can dream can't I?
Well there is normal dreamin' and then there is smoken' some REALLY good stuff and then dreamin' lol.Quote:

well I know my Qcore can do 4.2ish, and I score 16K on water @ 3.4 so I am sure its a real possibility.
If I can get 3.8 on water, MAYBE even 4...............(I can dream can't I?) I might be getting a phase unit, if I do, well..............there will be fun to be had..................
Yeah ya just need the CPU/System speed to get there.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:
