i cant get my GPU higher! :mad: only 320MHz @ 1.77V.
upping the voltage decreases stability. GPU is watercooled.

A2 or A3 core? My A3 core aircooled doesn't hit really high either :\ I max out @ 327... I was hoping for like 340 after hearing results from others. It all depends on the diff. chips I geuss.Quote:

try to change them, probably better solution ;)
Sys, you might want to update the first picture with Pin information (e.g. GPU Chip: Pin X, Mem Chip: Pin X) to help for those "at a glance" looks :)
does ANYBODY know if its possible to Vmod a PNY ti4200? us PNY owners seem to get ignored when we ask questions here.... :mad: :mad: :mad:
i just tried to solder the wires on the chips, guess what? i failed. The wire just can't stick to the leg of the chip. So i gave up.
What do you think is the problem? don't know y the damn wire just can't stick.
boys, i think to have found a very good Abit ti4200
today i'd tryed with MCW40, and it can do 365/650 without any artifact!!! the problem i that antec 400w can't manage my 1800@3ghz 1.85v & 80w pelt with this ti4200... so tomorrow i try with antec 350w for the pelt & 400 fir the system, and try to mod the ti4200 :D
I finaly made voltmod on my Leadtek, thanks for all the info in this thread
Here are two pics:

http://www2.arnes.si/~mlivak/Gf4%20d...olt%20mod2.jpg
I set volatages to 1.85 & 3.7V I can currently hit 350/670 no artifact, my deafult oc. was 320/615
You can see my cooling in liquid cooling part of the forum, a little later when I upload new pics.
ok i spent 10mins to read 4pages of this thread, and no one said anything about the ALBATRON GeForce 4 TI4200P TURBO.. im depressed :(
im going to buy this card in about a week, and id like to hit 320/720 that a few ppl have gotten. Now i dunno if the stock sinks will allow that high, but would anyone like to post a pic of this card and point out the exact spots?
im thinking of getting some pomona grabbers like the ones used on mobo vmods, incase i happen to try anything.
What kind of pot would i need? im not looking to vmod it that high.
but i just dont really wanna remove the stock cooling. at least till like 6months after the card is old. so i cant ööööö about breaking a 200 dollar card :)
Thanks
well if you want to reach 320/720 don't buy the albatron p turbo, the most of them won't reach near that, 2 guys on unreal.pt forum had only reached 300/650 that is not nothing special for a so expensive card, think twice...
Ehh, that's because the albatron 4200p turbo is totally different layout than the 4200's we're working with.... and ya know there is a whole other thread on the albatron. Go check that one.Quote:

sorry but now i've modded my Abit ti4200 but have some doubt on it's mod...
i've connected the 2 pin11 of volt regoulator to a 5k trimmer and so to ground...
set resistance for vmem to 1k, and read about 3.6-3.65v...
set resistance for vgpu to ~0.85k and read about 1.92v...
this is the maximun overvolt that card can do without problem.... if i set vmem over 3.65 i have a lot of artifact and crashes.. the same with vgpu over 1.92...
this with watercooling+plet for gpu & ramsink for mem...
isn't it strange???
Just recieved one of these Albatron Cards from NewEgg,
and I must say im quite disappointed with it.
I'm not sure what card the hardware sites are usin to write their reviews by :confused:
but I assure you it must be different then what I got.
The one I have is only clocking 290/620 without lockups
or SERIOUS artifacting at anything much above that.
My lil abit 4200 (rest in pieces) kicked this pos's ass!!!! :mad:
edit: After work today im gonna pull all the h/s's off
and clean it all up and put it back together with some
A/S and see if that improves anything. But I kinda doubt it.
I see a RMA by the end of the day :(
Peace
WannaGoFast
Dam, Wanna...that really sucks. By the sounds of it, the first shipments of those Albatrons really clocked like mofo's while the latest ones don't seem to be fairing very well :(
RMA that thing and try another Abit....save urself a few $ anyway.

Hey can u get me the numbers off the card? i got mine from newegg also, and when i ran 3dmark @ 315/625 i got Alot of arifacts. If you rma yours gimme the numbers off both cards cuz i wanna see if i should rma mine. im thinking about emailing albatron and see if theyd gimme any advice.
Thanks
ok i emailed Albatron usa (there actually local to me about 15mins away) About why the cards artifact at low overclocks. So hopefully they'll be nice enough to send me an email back w/ some advice or a fix. Cuz i didnt pay 200 for a damn card that wont do ti4600 speeds w/ modding. :(
Amen to that!!
Especially one that boasts (and i quote new egg)
"Wanna Get Ti4600 performance with Ti4200 price???"
in their sales pitch.
Most likely I will RMA it and just replace my broken
Abit ti4200 with another of the same, and save myself 50 bux!
Please post back if you hear from Albatron,
as I'd be most interested in their reply.
Also, if you can be a bit more specific about
what numbers you would like I will be glad
to post them here for you.
peace

i just did this mod to my AOpen Geforce 4 4200 128MB.....very nice
so far i'm at 325/477 (rivatuner reports 324.5/472.5)
i just finished soldering the vmem pot on however i have no way to measure the voltage (caps are not the same and there's only one cap that i can measure from and thats for vcore) so i'm kind of shooting in the dark....isn't that scary? hah
i guess i jack up the mem frequency and if i get artifacts i give the pot a turn :)
finally 375/720 & 16.8k in 3dmark :D :cool:
vgpu 1.92-3v
vmem at 3.6v
doesn't accept any highter overvoltage... soon gpu lapping ;)
Is that without heatsink on your ram?Quote:

just wanted to show off my modding work. the ramsinks with vmod netted me 53mhz over stock overclock. the vr's are glued to the pcb so as no accidents happen when working around the card
http://www.gospelforyou.com/other/MSI_ti4200.JPG
What cooling do you have on the GPU to get 340mhz?
Currently the gpu is stock cooled, want to put a larger cpu heatsink on but dont really know the best way or a good one to use.
i want an alpha 153u sink, but there like 33 dollars..
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.
http://mechlin.fm.interia.pl/msi.jpg
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:
http://digilander.libero.it/ccuratola/4200.jpg
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
