Hey!
i'm looking for a way to voltagemod my old pov gf2ti just for fun.

It use's this voltage regulator for gpu and ddr..

I want help figuring out what to do. I can probably measure things if needed.

Well, I am not Macci or DDTUNG, but I am always curious of any pin/wire that is blatantly labeled VSEN1 & VSEN2.

Ya should remove the card and check the resistence from those pins. Place red probe on pin and black on a ground. Use either pin11 or something metallic not carrying a current to ground with.

Ya, i was thinking about vsen1 also but i need to shut of this computer to measure and i havn't got to it yet but i will in a minut or to i will post when i have measure it....
But you could see what resistors should be used on the grafic card on the datasheet. I though that was enough thats why i havn't measure yet.

I measured 65 Ohm at VSEN2 and 205 Ohm at VSEN1

So what do y'all think?
I guess lowering the resistance would give me higher voltage?
So should i try connecting a 1kOhm VR to VSEN1 or 2?

Typically the voltage to mem is higher than core..so if ya gonna do anything..keep that in mind.

Be careful with that 1k VR as it will raise the voltage quickly per turn.

Guess it cant hurt to give her a try..be sure it is set to max resistence b4 you solder it on.

I know basic electronics(i've read some in school, some electronics and direct current classes..) so ofcourse did i keep that in mind ;)

But i already tried it now (Vsen1 = gpu) and it didn't make any difference at all :/
The voltage staid at 2.05 no change.

Are you sure that you did the vmod correctly?

2.05 is higher than most to begin with from what I have seen. It is generally somewhere around 1.6-1.7v.

No its a god damn geforce 2 titanium it uses 2.05 to begin with.

Yes, I solder it to the VSEN1 lowered the resistance to about 160 Ohm (200Ohm before) it made no change at all. It simply has to be the wrong way. Maybe i have to try the fb and comp pins....

Good luck.
