7900GT vMod guide (from extremeoverclocking.com)

[Alchemy1]

I found this guide (http://forums.extremeoverclocking.com/showthread.php?t=216265) in progress and thought it would help some of the guys over here who are interested in vModding their cards. I know there have been a few posts on vmodding this card on this forum, but this guide seems like it is going to put all the mods in ONE organized place.

I am going to replace my 7800gtx with a 7900gt within the next week or two. I read the articles about the voltmodding, and dont understand the conductive pen all that much. Do you just get the pen and draw a line from this two points? And the ink acts like an metal wire connection?

The guide also states about how stock cooling doesnt cut it with the increased voltage and clocks. Is it good enough, and/or what are others running that have done this vmod?

I have a 92mm fan attached to the heatsink of my 7800gtx and it works pretty well in dropping load temps down a few degrees. Not sure if i will do that or have to get an aftermarket cooler.

You need to make sure you get a conductive pen, or get a rear window defroster repair kit from the auto parts store. It also has conductive paint in it. The ink basicly acts like a wire, because its conductive. To do the mod, its best if you tape off the path you want the ink to go in, then apply the ink. Then pull the tape up and you have a nice pretty trace connecting the 2 points.

I have seen some guys running 1.4v with the stock cooler, but they get hotter than I like my card to get. I've never used the cooler that came on my card, so I can't tell you how well it works, but I wouldn't reccomend it for any volt mods, its really small. Mine went straight to 1.5v and water :cool:

I would say for any long term use, you need some kind of good aftermarket cooling for 1.4v and above.

I am interested in getting to 1.5-1.55v, so i will probably go with an aftermarket cooler. Might as well shoot high if I am doing it, ya know. I will stop by radio shack this week and get an ink pen!

For 1.5-1.55v, stock air cooling probaly won't be enough...aftercooling, if you care about your card, is a definite. It will thank you in the end :D
