Undervolting 7800 Go

realtadiquantu · 11-25-06, 10:35 PM

Regarding the laptop in my sig:
I have undervolted the T7200 to the following
6x .9500V
7x .9625V
8x .9750V
9x .9875V
10x 1.0000V
11x 1.0125V
12x 1.0250V
It runs stable so far =D.

I was wondering if it is possible to undervolt my video card? I have a 7800 Go.

~Thanks

Im not an expert on volt modding, but I dont think theres anything you can do short of a hardware mod.

You can but I recomend you see if your 7800Go has overheating issues and if it does, have dell send you the 7900GS card. Much cooler running card.

There's a bios for the go 7800gtx, but I'm not sure if there's one for the plain 7800 go (are they one and the same?). The bios editor should allow you to change the voltages as it does the clock speeds. Notebookforums may be a good place to inquire about doing the softmod, that's where I found the bios for my overclock (no voltage tweaking necessary).

What are good range temps for the 7800 GO?
I'd love to have a 7900 GS

80C or less is acceptible. 70C or less ideal. Some people report 80-90C temps, and that's just insane. You can also remove the stock thermal pad for some better thermal grease. I used some crappy 10% silver grease I had laying around, figured it was better than the thermalpad.
