i'm thinking about doing it on my leadtek.. only one prob... stock cooling probably wont be enuf do you think?... I want to hit at least the 11K in 3DMark, and my Leadtek only goes to 310/570 at the moment... looking at getting some copper ram sinks made up and a 120mm 108CFM sunon blowing over it....
Hi.
PLEASE help me!
In which points i can read voltage of memory and GPU?
There are few post in this forum but anyone is different.

or maybe:

or... ???
Lots of "OR"...
SORRY 4 MY ENGLISH:confused:
I have PixelView GF4 Ti4200 - 128mb, the VGA has two SC2602S IC regulators and Samsung TC40 modules. OK ... I did the mod to pin11 with 1Kohm for both IC. Cooling is no problem here, Big Ram Sink are employed.
Now my question: How come I see NO BIG performance difference in DDR speed after the mod? The memory speed stuck at 550MHz (default) and at 570MHz (with 1Kohm). Even some artifacts can be seen at 570MHz (with 1Kohm).
Can someone give me some tips?
Hi you guys..
4st of all, great post..
2'nd... I have a Leadtek A280 LE TD MYVIVO (Gforce Ti4200) with 4ns samsung ram.. with stock cooling it goes at a max 295/535.. and i think thats a low score...
has anyone modded this card or do any of you know if it will help me in my OC'ing..
I plan to make a cooling mod 4 it anyway, i just wanted to know in advance, before i start the big heatfan race.. :O)
my 3dmark

hey all
my MSI TI4200 runs stable @ 325/629 with artifacts somtimes and 325/625 rockstable and no artifacts
but i also really wanted to know how to voltmod my 4200 thx up front
People.... please help me. I want to volt mod VGA's memory, but mine is little bit different than the first generation of GF4 - 4200(NV25).
Mine is GF4 with AGP 8X (NV28), look at the pic and help me how to volt mod the memory. The IC for memory voltage regulator is ACOA 0236.
Lastly... I use 1K ohm for CS2602S, and the screen go blank instantly. So I removed the resistor and the VGA is okay. Should I use bigger resistor such as 2K ohm ?

What about this? It's a PNY Verto Ti 4200 64MB:

It is completely different from any other 4200 I know...:confused:
On the chip with 7 pins by side in the bottom right (the one marked as U816) it is written: P22SL - 74ACT08.
Julian if you run a search there is a PNY 4200 specific thread, but I don't know if they found a solution. :(
Looking at your card though, you do have 2 of the same SIZE voltage regulators as on the reference design, but they're in a different spot..
Now I'm not sure if there are any more, if those are the right ones or whatever, but I would say take measurements on pin 6 w/ a multimeter and post up in here. Maybe we can get somewhere from there.
Also can you give the numbers are on those two chips on the top left? ( U815 and U813 on the PCB ).
That may help us figure something out! :)
Unlikely nobody found a solution for this pny card in the specific 3d...:(Quote:

However, I can write here the number of the 2 chips U813 and U815:
- U813: 51031 - 72Ai
- U815: TL431C - 26M - C2Y2
I don't have a multimeter, so I can't read out the measurements on those chips...:(:(
Actually I'm looking for infos, but someone else will do the mod one day! :)
Nevermind my rantings... that's not the same votlage regulator as what's on mine :P I'm so dense :P It's the same size as the one on my A7N8X's memory... god I'm stupid :PQuote:

So it's impossible to mod this pny? :eek: :(
I'm sure it's possible, but I certainly dunno how to :(Quote:

anyone knows whats the lowest resistance value for vmem and vcore? what i mean is, i know that over 2/2.1 on the core the gains are more heat than Mhz but i don't know what resistance value to get that voltage...also anyone knows how much is too much on the mem?
i'm going to waterchill the core and put some tt ramsinks on the mems...
I've done 1.95v (which was optimal) on my 4200's core but that was cus I was aircooling it. The memory on the other hand I found 4.05V I believe to be the best. Anything 4.00V + though and you risk possibly frying something.... So be careful!Quote:

i have the pny vertigo ti4200 and it does 318/678 out the box (it came with heat sinks already) im trying to v-mod it so i can come for mr.icee (i wish) but the problem is every guide i find on how to is talking about the SC1102 controllers being on the back and there arnt any chips on the back does any one know what i should do?????
btw i have the same exact pny 64mb vertigo as julian and im having the same problems....some one please help if ya can
heres my ti4200 ....theres no memory chips at all on the back:confused: :confused: http://www2.freepichosting.com/Images/52828/0.jpg
