Can't really help ya w/ the mod, but out of curiosity...which 4200 do you have? I've currently got the Gainward, and its not a very good oc'r @ 310/570. The Abit is set to arrive at my house tonight...hope it oc's better :)
I've got an Abit and it hits 305/600.
was hoping for more than that but either way, its better than this gainward...btw it took a CPU cooler on the GPU to get over 300MHz. I'll report back tonight what I get out of the Abit.
Thx for the info. And if you find a vmod, plz post it back here ;)
This is stock cooling, your welcome, and I'm gonna continue to ask and look for that volt mod ;)Quote:

Cool, nice to see that the Abit roxx, looks like I will be getting one as soon as I go to Italy, I can get it for 200$ there.
I will need the Voltmod too, and I hope we get some info in this forum..
all i got to say about this abit is WOW. I got her tonight and right out of the box after working my way up i've hit 325/614! :)
330 locks, 615 gives a couple artifacts....amazing card...easily smokes the gainward. gonna mod the gpu cooler a little then and see if the core goes up any higher...but damn, great performance right out of the box.
edit: room temp about 73F.
Damn! My ti4600 hits 325 only! These little ti4200's certainly have lots of muscle behind them!Quote:

Ur tellin me :)
Pretty sure what I'm gonna try next as far as GPU cooler mods...but undecided on ramsinks or not as of yet. Don't have any experience w/ ramsinks, so not sure what to expect out of them.
Gainward 64MB 4200 w/ VIVO max clock: 300/570 (CRORB on GPU)
Gainward 64MB 4200 w/o VIVO max clock: 310/580 (CPU cooler on GPU)
Abit 64MB 4200 w/ VIVO max clock: 325/614 (stock cooling so far)
That's w/ 3.5ns EtronTech chips on the Gainward, and 4ns Hynix on the Abit. Either those EtronTech's suck, or Gainward has some crappy circuitry on these boards....
Very happy w/ the Abit...I'd recommend it to others looking at the 4200's.
You guys made me quite happy that I am getting this card, but the RAM doesnt look top, if it were only 3.6ns.Quote:

Do we have a Voltmod yet? Maybe in some other forum?
I am looking forward to Sysfailures coldplates too:D
I'm drawing out the ti4200 dimesions as I speak, and the 4600/gf3 plates will be done next Friday.Quote:

What in the fsck!? Look at this review of a Visiontek ti4200...
http://www.beyond3d.com/reviews/visi...200/index2.php
Look at the oc!! That is ludicrous.
WTF? well I cant change my mind, cant get any other GF4 for 200$Quote:

oh edit I found this: " The Ti4200 was overclocked to 325/535MHz core/mem for the 1600x1200 + 4xAA + 8xAniso test to see how much more can be gained from overclocking :"
So... still a healthy GPU OC but the mem is realy not stunning.
Yea, I saw this this morning and knew that memory oc had to be a typo, lol. Then I also saw what Malecky caught...and confirmed my assumption :)
Well I still am hoping for 700DDR with serious chillin and a voltmod.Quote:

I did 520mhz Easy with the same RAM no HS on it with a R8500 if it were cooled it had been 540 which is a lot with just some Al on it.
I've spoken to a fella on the ORB w/ the Abit @ 668MHz memory w/ merely ramsinks so I don't see your goal being out of reach ;)
Talking to this guy is one of the reasons I decided to go for the abit :)
oh.. come on..
i need a ti4200 volt mod too ;P
bump :D
Can someone give me the PCB layout or the chip that controlls the voltage numbers? we can figure it out aurselves or just write to Abit:DQuote:

Sys can you tell me is it a controller or is there a PCB design involved like the Radeons. If its a chip it is simple like pie.
This pic of the back of the board might help:Quote:

I see something interesting in the upper left corner of the card, might be a vital voltage regulator.
And the bigger chip over the Siluro print... but I dont know anythin maybe write down the markings on that chip and search the net, if you insert the chip name in google for instance you never know what comes up.
Gimme a top shot if you have time Sys.
Looks like the Ti4200 uses two SC1102 controllers, one for the Vgpu and one for the Vmem. From the picture alone it is difficult to tell which is which. Can someone measure the resistance between pin 11 and ground for both ICs with the card unplugged?
Also need someone to find the caps to measure the voltages from(one leg of the cap is ground, the other is the voltage you want to measure).
Be careful, don't fry anything.:)

From the looks of it, i'd say the IC closest to the VGA connector regulates Memory Voltage, while the IC on the opposite end of the card regulates GPU Voltage.
Got a 64mb Siluro Ti4200 on the way guys :)Quote:

Jup looks easy but I'm not 100% so till DDtung says so I am not gonna do anything.
whi hasent anyone modded this card before?
Who knows! It's gonna be really good when it's OC'ed ;)Quote:

As long as were on the subject of volt mods, does anyone happen to have the pictures or a descent write up on how to do the vmods on the ti4600. There were some pics over at icrontic from macci on this but it seems like those pics are unavail on the server now...
i would be just pleased as punch if someone could post those pics or let me know where this info is avail..
Thanks.!
You can possibly Private Message Macci and have him post the pictures here. ;)Quote:

You da man sys!!:cool: Those were exactly what I was lookin for.. uhhh, perhaps my search wasn't quite 'exhaustive' as it could of. :o Now all i need is one of your coldplates..:D
DDTUNG,
I have this card but this Auto-Ranging Tester is all I have for taking measurements. I also must admit that I'm not too familiar with it nor am I very knowledgable when it comes to working with electronics, lol.
If noone else has already given u what u need and I can do it with this meter, please let me know how. :)
That's work just fine.
Let's get you started with measuring the resistances. First make sure to unplug the card from the mobo. Look for pin 11 by starting with pin 1 next to the dot and counting anti-clockwise. Set your meter to read ohms. Put the red lead on pin 11, and the black lead on the mounting plate of the card. Your meter should give you the correct reading. Repeat with the other IC, then postt the readings here. I will then you detailed instructions for reading the voltages.:)
DDTUNG:cool:
Mwaha me to the rescue. I borrowed my neighbors ;)
Ok the top right one gives me a Ohmage of 105.
The top left one gives me a Ohmage of 124.
Lemme know what I have to do next and I shall oh master :)
i also got 124 for the top left however got 102 for the top right :)
seems close enough!
sry would have replied earlier but I've been benching ;)
I just rechecked the top right and now I'm getting 104. Heh.
Thanks guys. Now get yourself two 5k VR. Solder one VR between pin 11 of each SC1102 and ground(any point that reads 0 ohm between it and the mounting bracket). Adjust the VR to 20 times the resistance you measured before(20x124 and 20x104). Assuming that you have found the capacitors where you can measure the Vgpu and Vmem, you will now measure slightly higher voltages at those same capacitors. Turn the VRs slowly decreasing the resistances and watch the voltages go up. Your maximum voltage depends on your cooling on the core and memory.
Take your time and go slowly. Don't fry anything. When in doubt, stop and ask for clarification.
DDTUNG:cool:
Thanx DDTUNG Yu Rulllleee:banana:
Just have to get the card now:banana:
edit: Anyone have a spare Tec and how big should it be power wise.I can get one 156W used for 50$ but I think its a bit of a overkill Tec;)
is it possible to find the mod for a Gainward Gef 4 4200 pleaze?
or have i to sell it and got me a Abit siluro? :D
Thanks!
(searching for photos)
had 2 of them gainwards b4 i got the abit. do urself a favor, sell it and get the abit, lol :)
Weee, alright Imma order some right away!Quote:

yep i'm just trying to sell it ;):D
but i thinks with a mod i can do a good oc on this?
you oc with gainwards?
332/627 is w/o mod...stock cooling w/ a low cfm 80mm blowing up on the card and one blowing down on the card....no ramsinks. i wanna measure some temps and stuff before i even think about vmod :) been busy!
good ;)
here i've got a 32°C ambient :(
i'm gonna put a WB on the gef ;)
thanks
N8, you've got one killer Abit. A volt mod on it is going to OWN!
sysfailur,
thx :) I just have to think up what I want to do as far as cooling the core. I have an idea, and it will be only air-cooled btw.
Anyway, I'm doing alot of other testing right now, not video card related, so it might be till next week till I get to messing with it. I'm prolly gonna ask someone like cabojoe to mod it for me if i do so, cuz I'm not too handy w/ the solder and he's a good bud :)
Hi guys. I have an Innovision Tornadoe Geforce 4 Ti4200 128 mb, using Samsung 4ns rams. Havent gotten around to overclocking it yet, but have done some preparation for voltage mod with help from this thread.
My card is very similar to the Abit's. With reference to Sysfailur's pic, it has the same SC1102CS chip at the right hand side. And like you guys, I get around 104 ohmage from pin 11. However, it is lacking the SC1102Cs chip at the left hand side. Where the chip should have been, there are metal contact point traces like someone forgot to solder on the chip. Of course, I don't think someone actually forgot. Now I think I've found where to measure the voltages from and I think its the same with the Abit.
This measures the memory voltage I think, and it gives me ~ 3.25 - 3.27v
http://bravo.ausgamers.com/lardarse/lard/back.jpg
And this measures core I think, it gives me 1.66v.
http://bravo.ausgamers.com/lardarse/lard/front.jpg
I'll be getting a VR to solder to pin 11 to see if it increases voltages. I think this right hand one controls memory voltage. Now with regards to core voltage, I dunno how this board controls it since I'm lacking one SC1102CS chip. Could the memory and core be sharing the same chip? Can't seem to find any other chips. There's one SC3.3 chip infront near the core but the Abit board seems to have it as well. Any ideas?
Good info! I'm not sure about your missing chip dilema... I hope someone here can help ya! Perhaps a high res pic of your card might help us identify a chip?Quote:

Found a 100k ohm VR lying around. Set it to around 2000 ohms and soldered it to pin 11 and ground.
Turns out the right hand chip controls the GPU voltage, and it raised my default 1.66v to 1.74v. I'm not gonna turn it higher until I get better cooling. (peltier/watercool :) )
So now where's my memory voltage regulator?? I don't have a digicam ATM, but the place where you have your second SC1102 chip is bare for me, but has metal contact points just set nicely almost as if someone forgot to solder on the chip. Do you think soldering a VR to the point which would coincide with pin 11 would help up my memory voltage?
Also, do you think my Samsung 4ns rams would overclock better with a voltage higher than the 3.25v I'm measuring? What voltage are they supposed to run anyways?
DDTUNG i need help :);)

Well your card looks exactly the same as the Abit board... you have both voltage chips. So do what has been previously mentioned. (You still might want to check the Ohmage of the 2 pins mentioned before.)Quote:

Thanks in advice
Sysfailur, does your Abit come with 4ns rams? How high could you get them with stock cooling w/o ramsinks?
Myine only goes up to 510 without artifacting :(
It does come w/ just 4ns, and I got mine to 600 before it locked up. With more cooling I think I could get it higher as I didn't get any artifacts.. it just locked up.
k i've to measure the ohmage between pin 11 of each SC1102 and ground ?
but i don't understand where to measure the Vgpu e Vmem :/
(it's a bit difficult to me to understand technical english)
10x!
Hi. If your card is similar to mine then here should be the points to measure, + end of meter to + of cap and - ground.
http://bravo.ausgamers.com/lardarse/lard/fronter.jpg
There should also be pins from the same cap behind the card so you can measure from there as well.
My Inno3d card is good for its price, but definitely not overclocking friendly.
It lacks the SC1102 controller and some other chips that regulate memory voltage, so I can't even tweak the voltage. I even soldered a variable resistor to the bare metal contact point where the pin11 of the chip is supposed to be but it didn't do anything. Many parts that are present on other boards are missing on this one, probably to cut cost. I can only change the core voltage with this card. And my stupid memory produces artifacts above 520 mhz, without any ramsinks on.
Well, at least I have an A3 core which is supposed to be better than an A2.
I like to play games at high resolutions. How badly will this bad memory overclock affect me?
anybody has done the mod yet? :)
it's going to be my first mod on a vga card..
is it risky to measure the vgpu and vmem?
Anybody could tell me which fixed resistence to put instead of the pot?
i'm gonna have a wb on the chip ,not peltier..and ramsinks !so.. not much voltage :D
:)
:(
Hi Space.
If you've read my post, I've done the measuring without any problems and the mod to the core which is the right hand chip without any problems as well.
Hi lord :)
yep i've read but i don't feel so confident :/
if i sold a 2k resistor on pin 11 on the Sc1102 i've 1.66@1.74v
Should be right if cooled by a normal WB ,no chilled water?or is better 1.8v ?..
the vmem... to me seems not so easy
i've read here some problems http://www.xbitlabs.com/video/visiontek-gf4ti4400/
with the vmem.. the layout is so different the this one is enough?
my friend told me that measure the V it's quite risky.. and i'don't wanna fry the 4200 so early :D
was it wrong?
a mod like this how it works? http://www.xbitlabs.com/video/vision...em-volt3-f.jpg
all i need is some who has done the mod and give some advice
thanks ;)
I haven't had the time yet to do the mod. I'm working on it. Just rearranged my computer area.
I'm sorry, the memory voltage measurement isn't where I said but here.
http://bravo.ausgamers.com/lardarse/lard/fronting.jpg
I've soldered a VR to the left hand chip and it gives me 3.31v at maximum resistance and slowly upped the voltage as I reduced the resistance. Had it up to 4.06v, but it seems voltage doesn't affect the ram overclock that much.
Be careful now. I just fried my rams with too much voltage at an artifacting overclock. I was running at 3.95v, and then decided to up it a bit more, but over tweaked the pot and system shut down. A boot up gave me a totally crapped screen. Thats with Samsung 4ns. So watch your memory voltage! 3.6-3.7v is the max I would want to go from now on.
Good advice, thanks. I'll be sure to be careful when doin that ;)
What cooling was on that memory when u fried it, lardarse? :)
They were ramsinked before I fried it. I think it must have gone up to perhaps 4.5v when I fried it. It was an accident that I overtweaked the pot.
Anyways, changed it for a new card and now I'm running just 3.31v memory voltage, default's around 3.26v. I dont know why tweaking the pot doesn't change the voltage for this card. Its the same pot I was using on the fried rams. Perhaps it got damaged when the ram fried. Anyways, this just gets me around 610 mhz artifact free. For the core voltage, I tweaked with another pot from 1.66v to 1.85v. Now I'm cooling the core with a watercooled 80 watt peltier. This gets me around 333 mhz core without locking up in 3D. Think this core is rather old. Its a 0152 A2 NV25 core. Think its built in 2001 week 52. I have had a better core once that was A3, but I sold the card.
My SUMA card uses these SC1102CS chips also, and they're placed in the samed position as on the Abit, so I guess I've found what I've been looking for so long. Only have been here one day, but I already love this forum :p
I'll be measuring the resistance in a few minutes, and if I get the same readings as on the Abit, I'm off to get me some VR's :)
This SUMA card owns btw, it does 310/655 out of the box, carrying 3.3ns Hynix chips.
Watercooling is due by next month, so we'll be seeing a frying SUMA pretty soon ;)
3.3 ns!
I'd be happy just to settle for 3.6 ns!
OK, measured out the resistance, and I'm getting 111 for the top right one (or was it left? :)) and 102 for the other.
Didn't have anymore time to get to the electronicsstore, so them VR's will be something for tomorrow I hope.
Grrreat :)
Low folks,
by tuesday I should have my new SUMA GF4, and off course I'm going to Vmod it.
My previous attempt having killed my GF4 wont stop me :)
But, I want some explanation, basic explanation actually.
See, I really suck at electronics, and I mean that I don't even really know the basic stuff.
So, the card I'm getting is a 128MB SUMA Ti4200, it's on 8-layer PCB and carries 3.3ns BGA ram, according to the guy from the store I got it from, these cards do 690~700Mhz memclock on average. So I won't be touching the Vmem for now.
But what I wanna know is how to connect everything for the coremod in exact words.
What I assume is that I solder on a wire to the pin needed on the regulator (don't know which regulator it uses yet, but I think the SC1175), that wire goes to the middle leg of the potmeter (I use 4.7k pots), then another wire from the leg you measured out to ground. The pots set to 0 ohm, but I know now that I have to set them to max resistance, so 4.7K :D
Is it correct this way, or not?
Don't wanna fry another GF4, really don't :)
where did you get that card, and how much?

313e to my doorstep.
Noone that wants to answer my question(s)? :(
sorry for the annoyance, but how much is it in $$$?
and do you know if they ship to the US?
The wire msut be soldered to the correct leg of the chip and the other end to your resistor. You must also have a wire from the other free leg of your resistor that runs to ground. Thats it basically.
one Euro is 0.99$, so it's 315$ :rolleyes: (lotta money for a Ti4200 huh? :))Quote:

Can you guys help me with my volt/mod. Ok I have a Ti4400 and it uses the sc1175 for GPU/volt. and it is at 123 ohms my question is that before you stated that start your 5k pot at 20x that number why is this like turning the resistance off totally untill you turn the pot to where you want it? also if I connect a 5k pot set it at 5k will it affect my 1.66v alot or not at all..thanx
Just set the 5k resistor at ~ 5k and after soldering, slowly decrease the resistance and check the voltage consecutively.
LardArse , what resistance do you use for the VMem ???
I think I started with around 2k, and that gave around 3.34v and then slowly went down. But for 4ns rams I have, it doesn't help much at all.
if i have a SC1102CS chip why don't do this mod?

soldered a 1kOhm resistor to pins 11 and 14 of the SC1102CS chip:So, the R8/R7 ratio (in the typical application circuit scheme) changed and the regulator's output voltage grew from 1.66V to 1.81V.
and this for sc1175csw

Vout1 was increased with the help of R14 720Ohm resistor, which was soldered to pins 18 and 20 of the controller chip.
The graphics memory voltage increased up to 3.09V
Might wanna use VR's though, not just resistors ;)
k but instead of solder a Vr to the pin and ground..Quote:

ins't better to solder to pin from pin lke these?
can i fry the card if i test the vgpu with the pc on? :(
Well I wouldn't directly solder the VR on.... use some wire. ;P
I have a Msi ti4200 and te pcb seems to be the same as abit siluro ti4200
but the regulators have the same size but are
sc2602s
0219
g28995-2
an i cant seem to find the pdf for these at semtech maybe they are just too new :(
does anyone know where to find these?
thankz for the reply
so i guess it´s the same pin11 :)
what was your gain from 1.66v to 1.81v ?
and the gain from the crappy stock cooler to peltier ?
:)
No idea. Went straight to pelt before overclocking the core. :)
Went up to 2.1v and the max I could manage was 345mhz core that seemed stable but didn't test it that long cos my mobo/PSU can't keep up the high voltage and shut off. Right now its 340 Mhz at 1.96v.
Tell me how much yours overclock, especially interested to find out about your memory overclock. 600 memory works fine for a while but turn up the resolutions + FSAA and stuff and artifacts start appearing. Only 580 artifactless for all situations. Be careful with the memory voltage because I fried my previous GF4's ram with too much voltage.
it does 625 without a single artifact
hynix -3.6
the gpu is crap 297 for 24/7 usage
Well you have better luck, mine's 4ns Samsung :(

did you do the mods Skatan?
Well, I just received my GF4 Ti4200 today, and it seems to be performing very well.
Brand: "Xelo" (Cheapest I could get in EU: 150$)
Core seems to go up to 330 with stock cooling. 3D marks craps out after a while though: cooling is utter crap and GPU get's really hot. I'm going to slap op my DD WB on in a few minutes. Keep you guys posted. :)
Mem seems to be average: 4ns Hynix, does 580 without artifacts and run hot.

nope :)
i´m thinking if it´s worth the risk :)
i moded my previous gf3 (non ti) and the gains where great
20 mhz on gpu and ram
the ti´s dont seem to gain that much with vmod , only extreme cooling
I just wish that there was a good vmod to the gf4 ti4200 ram as there was for my EX gf3
and the gf4 gpu gets very hot without the mod , and vmod needs very good cooling
if i was convinced that it would give me 20+ mhz on the gpu setting the voltage to 1.74v i´d do it without thinking just for benching :)
(i have pretty good soldering skills :) )
