The Galaxy short PCB card I have has an RT9259 DC-DC converter on it, so we should just be able to add a VR between the feedback pin (pin 4) and ground. I'll hopefully get around to trying it tonight and report back if successful.Originally Posted by NonDecepticon
If it works out and nobody gets to it before me, I'll post some pics when I get a chance.

AwesomeTo get a vGPU reading, would we be able to follow the trace from pin 4? I look forward to it, I am really curious if the different regulation on the short board and in the Galaxy's case dual PCI-E connectors (supposedly discrete GPU and MEM supplies) will provide for some interesting overvolting results
I discovered something interesting. . . my 512MB Galaxy 8800GT has a vcore of 1.22V idle, 1.26V load. This is without me doing any mods. If this is common, it could explain why people have been having such good luck with this card.
Dissapointing for me though, since mine will only do about 700 / 1728 / 950 at that voltage.
I did the vcore mod anyway, and I'll try it tomorrow morning to see if it worked. Need sleep for think more now.

mud, what is the cooling of your card? Freq could go a lot higher if you can get it cooled below some 50° under load.
That's possible. Right now the card has its stock cooling, which is a Cooler Master heatpipe orb thingy that works fairly well:
Load temp with 1.23 vcore is about 77 C. I may try putting my maze4 on it at some point.
As for the vcore mod, I must have been asleep last night. My non-modded load vcore is 1.23V (still really high), and the mod appears to have worked. I still need to do some more testing though.
