i traded for it. its a XFX Alpha Dog Extreme Edition 640m (PV-T88P-YDE4)

i found the ovp mod :p i removed one resistor that was conected to the ovp pin and it had 114k when it was soldered and i replaced it with a 500k Vr and i set it @ 140k now she has ovp from 1.3 to 1.45 Volt i will post photos later today if someone has the same card the strange thing is that the resistor was from the side of the card where the voltera is :/
anyway now i can bench the core @ 870 @ 1.4 volts it's seems a litle crappy but what can i do :p
i need to find caps now :/ anyone know what caps do i need :p ? 1600 μF 6.3V are the ok ?
if anyone needs this
this is the Ovp for the axle 8800gt
remove the second resistor and solder one 500k Vr trim it to ~200k when it is soldered and you will get ovp @ ~1.45 V trim it to a higher resistor and the ovp kick will raise more

and this is the Vcore mod 50 K Vr to Ground

and these are the measuring points

and this is the Vmem Mod ( that i haven't test yet so until i will i take no responsibility if anyone burn his card )

Great job Panos (Vatos_locos) :up: :clap:
You sure went through these data sheets really carefully :D
i just done with the mems mod and it works fine :)
@ Quake6 :
What were your final results? I have been waiting patiently for some better info on this alpha dog vmod. Previous posts were a little unclear on were the solder points are for the VR.
has vMEM pencilmod for ECS 8800GT 256mb?

anyone?
post o a good pic of the voltera chip ;)
the square one in the middle end of the card
not sure about pencil mod but mem chip is on other side of the card at the rear

ecs 8800gt has been cover'd in thread :)

Hi Guys !
I am looking for pencil or bios vmod for my Palit 8800 GT non refernce cooling. But i can`t take of my cooling system from my card becouse there is a plug.
ok i got my new gt in and i want to voltmod it. were can i find a 500Ω VR?
Does anyone have or can anyone help with the ocp mod for this xfx 8800gs (same as gt) please ? The ic is labelled BN-9H.Thank you.

Hey thanks.This is about as good as my camera gets.If you need macros of specific areas i can do that or i can borrow a camera for better pics of the whole pcb.

OK you gurus! Anybody knows how to do the OCP on the Galaxy 8800GT? Mine card is already voltmodded (look at post # 832) and I came to a limit on LN2. It looks like 1.5V under load it the end of this card. Need the OCP mod now. :shrug:
HitandRun,
OCP: find a surface mount resistor connected to pin#35, measure resistance across the resistor (basically between pin#35 and ground). Solder a VR rated ~20 times the measured value across the resistor. Lower resistance to push back OCP trigger point.
About OVP (as per PM)....
Does the card crash if you increase voltage without any load on the GPU?
About OCP/OVP looks like I was lucky, 1.55v on load (aircooled) without any trouble
