Hi PAIIITET,

Please can you give more details about your voltmod?

Do you have pictures or links to get more details?

Thanks in advance,

NICE MOD

Love those, But default cooling will kill that card 4 sure

**CyPh3rin** · 10-16-2006, 07:37 AM

**CyPh3rin** · 10-16-2006, 07:40 AM

Hi to All,

I confirm that the Vmod works OK with Club-3D 7800GS (G71).
I can overclock the GPU to 720!!!
I made the pencil mod for the memories and reach 780!!!

But for some reason I can’t do that at the same time.

I can’t pass 650 with the memories if the GPU have the VMOD to 1.5v.
So now I have the graphic with 650 / 650. I will like to put them at 720!!!

THANKS PAIIITET FOR THIS INFO!!! And do you have any idea why I can’t do the overclocking at the same time?

CYA!

Guys I'm a total nub or something I guess lol I have a *eVGA 256-A8-N505-AX Geforce 7800GS* it says in the nvidia control panel that it is a G70 core but I was sure this is a newer card thus have the G71 core im confused could someone comfirm if I have a G70 or G71 plz

to be sure, look under heathink when your putting a aftermarket cooler on it. you should just to help things out on the o/c and its gonna run alittle hotter.

**CyPh3rin** · 10-18-2006, 07:28 AM

need to know if its G70 or G71 though so I know which mod to do....

**CyPh3rin** · 10-27-2006, 01:34 PM

someone help please

**Jochenp** · 10-29-2006, 10:02 AM

There is no way to know it but look for yourself on the core.
nVidia control panel just states what it's supposed to say, if you ahve a 7800gs it is programmed to say g70

**Zardokk** · 10-30-2006, 07:48 AM

Remove heatsink. Wipe off thermal paste. Look at core. See whether it says G70 or G71.

Interesting, what this you way has done voltmod on 1.2 and 1.3 and 1.4

Show the photo.

Something I you not faith

Through VID possible to do only 1.15, 1.5, 1.55

**OCPerformance** · 11-18-2006, 03:04 PM

hi

you must remove the light blue VR

Masse (German) = Ground

on the chip are all 1

VID4 to ground is 1.2 V
VID2 and 4 to ground is 1.3 V
VID3 and 4 to ground is 1,4 V

do you want to give more Voltage than 1.55 V ?

then I can help you

best regards

**PAIIITET** · 11-19-2006, 01:41 AM

To me necessary for 1.3v or 1.4v since by 1.5v acceleration of memory it decreases from 720 to 650 and very strongly make noise coils the capacitors

**PAIIITET** · 11-19-2006, 01:42 AM

two blue resistors it is necessary to delete?

**PAIIITET** · 11-19-2006, 02:41 AM

Thank you for your method
If we shall delete two blue resistors, that shall get by default 0.8V?

Code:

V4 V3 V2 V1 V0
 1  1  1  1  0

**OCPerformance** · 11-19-2006, 09:52 AM

thats right all are 1 -> 0,8 V

**PAIIITET** · 11-19-2006, 11:37 AM

2 OCPerformance

pls, show photo of its videocard with removed resistor!

-----------------------

I want delete resistor with right and connect VID4 to ground to get 1.3v

Code:

0 1 0 1 0 - 1.3v

Like, it is correct?

**OCPerformance** · 11-30-2006, 08:37 AM
