Gainward Ti200 VMod

[Ragnarok]

I been looking all over the web for a Gainward Ti200 vmod and since the gainward card dont follow the reference design, I am kinda stuck.

Has anyone here successfully vmodded a gainward ti200? or have any resources on it? (tried the search button already but to no avail)

[Micutzu]

Yeah , i need one too , for a XpertVision Ti200 , it doesn't have the SC1175 chips for regulators . Anyone ?

PS : APW7036 and APW7016 , those seem to be the regulators on this one , not sure though ...

[Chong345]

DDTUNG might know. I have no idea really. Sorry guys. Where's the spec sheet?

OK , thanx Chong , let's see if DDTUNG has some goodie for me :D .

If you got your Ti200 a while ago, like last year, then you can use the volt mod here. (http://www.maximumoc.com/guides/gf3voltmod.html)

The newer ones have new voltage chips, so will require something different but I've DONE the volt mod on the Gainward Ti200..... *points below*

Your a champ sysfailur thanks for that :)

Nice results too :D

I only hope he has that version. There are two versions and each has it's own set of chips. If he doesn't have what I have though, then well, I geuss we're gonna need good ol' DDTUNG :)

We will check it out later thanks Sys :)

Cool, glad I could help!

[Micutzu]

Too bad this vidcard has completely another layout than those , and none of those chips on it . I'll post some pics later today .

[Micutzu]

Ok here it is , it's taken with a crappy webcam , sorry for the quality :

[Micutzu]

And here's the back of the card . As you see , no IC's here ... :(

[Micutzu]

Nevermind , i've discovered myself :toast:

DDTUNG told me where to get the data sheets for the IC's , i've downloaded them and done the vmods myself . Here's a brief description :

APW 7016 is the volt regulator for the GPU . You need to solder 2 resistors here :
- pin 1 is the overvolt protection pin , you need to put a 100 ohms resistor from here to ground ;
- pin 8 is the feedback pin of the error amplifier , put a 20k resistor from here to GND to get 1.75V instead of 1.5V .

APW 7036 is the dual volt regulator for the memory (it requires 3.3V and 2.5V) . Another 2 resistors on this one :
- pin 16 is the overvolt protection pin for the first voltage (2.5V) , soldering a 470 ohms resistor from here to GND gives you 2.85V instead of the 2.5V , because it also affects the feedback circuit (pin 15) ;
- pin 7 is the feedback pin of the error amplifier for the second voltage (3.3V) , you need to solder a 510 ohms resistor from here to GND to get 3.7V instead of 3.3V .

This is pretty much all , maybe it'll help you too , Ragnarok . For any other info PM me .

[Ragnarok]

Thanx mate, was acutally looking for it for a mate :)

Will try it when we have some spare time

Cheers again

Hey, your XpertVision Ti200 looks just like my Palit Daytona GF3 Ti200 :)

I guess the volt mod, you described above, would work for my card too.

BTW have you noticed some printing on the PCB stating something about an Overdrive setting? Take a look here (http://www.xtremesystems.org/forums/showthread.php?s=&threadid=3470) and see if it looks familiar.

EDIT: I just found out, they are in fact the same!

Please take a look at the thread I mentioned and tell me what you think.

Was your volt mod successfull? How much did it increase your OC (please post b4 and after)?

Thanks. :toast:

[eva2000]

my Gainward GF3 Ti200 does 10,162 3dmark2001SE with default 1.5v http://service.madonion.com/compare?2k1=4656106

Yes , Daytona and Xpertvision are both Palit , so it's basically the same card . I don't know what's the deal with the overvolt jumpers , this particular card had the markings and the traces on the PCB for them , but they were not soldered there .
The results were not that great , because the card already had a great oc without the vmods (175/400 to 250/544) and the memory cooling was not that good (stock HS) . I only got the GPU from 250 to 262 and the memory from 544 to 552 . I'm sure that with better cooling i could've achieved more . Here's a score (it can do better , it's actually a friend's rig) : http://service.madonion.com/compare?2k1=4579143

[Cthulhu]

Damn, that's a helluva card you got there, mine won't go above 230/430 and that's not even stable. :(

Maybe I should gather up the courage and solder the jumper on there and give it a go.

[Micutzu]

I got myself another Xpertvision TI200 and it goes to 250/550 with no mods . Can't wait to put a good copper cooler on it :D .

[fraguzz]

:toast: I love you all, :D Not that way.... you know what i meen;)
I have a palit daytona geforce 3 ti200 64mbDDR!! and have looking for the volt mod for over 30days!!! FINALY
but oces already good 175.250mhz / 400.545mhz.

About cooling HAHA i have a modified Thermal take Volcano 9 on my gpu about 38C on the bagside of the card!! FULL LOAD, i have pictures if you want to see!! :cool:

I HAVE A VOLT MOD I HAVE A VOLT MOD I HAVE A VOLT MOD I HAVE A VOLT MOD I HAVE A VOLT MOD

tHANKS YOU RULL!!!

Ill get bag with results

[Micutzu]

Good job man , let's see some results :D .

[perco]

How do i check if my ti200 is the old version or the new?

[fraguzz]

:mad: oh ever sinse i made the volt mod my card does not work!!
maby i burned the volt regulater because it gets hot!!
but has not tried to fix it!! bought a gf4 ti4200 128ddr 8xagp

Do you have any photo of this v mod ?

[Buzzy]

Do you possess some picture vmoda to Palit Daytona maybe ? On my card I have different volt regulators on Gainward and XpertVision . On card I have volt regulatora which only 8 pins. I have TL431C, IWR229C, this volt regulators is near memory.. Can someone help me to design vmoda ? To my card ? My English is bad :( Please help me ;] My Palit Daytona overclock to 281/595 but i want more :) Anyone can help me ?

[marius7]

You are lucky. Mine want go over 500 @ memoryin 3dmark. The core works @ 240 but the memory is limited.

She looks like this (except mine is 64 MB and no TV-out), the same strange TL413C and I don't know how to vmod her
