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?

[Micutzu]

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

If you got your Ti200 a while ago, like last year, then you can use the volt mod here.

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

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

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 .

Thanx mate, was acutally looking for it for a mate

Will try it when we have some spare time

Cheers again

Micutzu20:
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 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.

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 .

[fraguzz]

I love you all, 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!!

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 .

[perco]

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

[fraguzz]

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 ?
