For all the following modifications, use multi-turn potentiometers for best control over the voltages. A suitable ground reference point would be the 12V PCIe power (http://www.overclockaholics.com/forums/#) connector. 1988

I'm still waiting to see one of these bad boys modded.

The 480 is temp limited like the 200 series, but extra GPU voltage seems to help stablize high mem freq. I'd bet the 470 acts the same way. I wonder if vDDIC is tied in with the GPU core voltage.

Man you got some super clean joints!! How the heck do you get your joints solid enough to press eraser over them without breaking them? WTF am I doing wrong. Mine are always fragile as hell. You solder skills are pro for sure.

Did try it out yet since I have been pounding on the E8700 today.

Thanks mate! If your joints breaking you need more heat. :thumbsup: I find higher temp for a split second better than low temp and holding the iron there for an hour. :D;)

I think its mostly a lack of skills. Ya I prolly need to do my mods at 30w instead of 15w though. What do you turn your station to?

I have no watt setting but temp. I set it to 700F to get stuff done. :thumbsup:

I've grown fund of using 15w with Rosin-core for most VR and vMeasure points and 30w with Silver-Bearing solder for caps and inductors. I really need to spend ~100 bones on a decent 'tunable' station, but it's so hard when I could spend it on another GPU. :blush: Bought a GTX260 today. lol, shortly after replying to this thread.

hahahha

15w? what temps is this in celcius? i have a analog temp regulated cheap station...

also 30w?

63/37 melts at what temps? the silver bearing needs higher temps i believe.....got info on the melting temps too?

Couple more pics added to post # 6. Gave her some heat sinks on the mem and pwm ICs and installed the pot. I guess you can call it pron and she is ready to go.

Yes sir! Back in the 8800GT days I was thinking about how to sink the rams behind the pot and that's what came out. These were actually made for the 8800GT but will do just great here as well. :cool3:
