8800GT voltage mods

[os008]

I also did the vmem buck mod to reduce memory voltage, and since decreasing resistance decreases voltage w/ that mod it is wired the opposite way, but the end result is that I turn counter-clockwise to reduce the vmem voltage.

Hey Jason, could you please tell me why you reduced the V-Mem? seems odd, don't you want to increase it to overclock better?! or do those chips respond better to lower voltage because of heat or other reasons? and what kind are your chips? thanks.


@Deluge
I feel what you're in right now, i messed up my 3850 the same way you did exactly. I used way too much heat on the soldering point, to the extent that the traces got burnt, and the resistor nearby got out of place. I replaced that resistor and it worked again. Got greedy and made the volt-mod again, but if you looked at the board before that last volt-mod you'd pitty it, it was a MESS.

Now you'd guess everything was fine, it was, i got the card from 667 to 950, stable and great ... BAM, shorted the PCI-e cable poles, imagine, losing the card NOT to the volt-mod, but to n00000000bness :P.

Anyway, i learnt my lesson, and took the pictures of mods posted by experts here as reference ... presoldered the wire, fixed it in place with glue BEFORE soldering it, meaning ... look at Jason's mod, you'll notice he used a stickie substance below the wire on the board. THEN soldered it in place with just touching the iron to the tip of the wire for 1 or 2 seconds, and i was done. Put the card in place and voila, it worked, thanks God.

So it paid off losing the first card; became more aware and a bit more tidy , though a very expensive lesson .


EDIT: Thought i would add the picture of my mod, though not very clear.
