ATI 3850/3870 Voltmod thread

[largon]

Hey guys, i don't know if this has been already posted in this thread. I just picked up an ASUS 3870, and it doesn't follow reference design. Here are some photos, any chance of pencil mod?

If you need bigger photos or something more centered/focused, let me know

Find where the pin marked with number 13 leads on the bigger chip. Also, a better shot of the cropped area with good lighting would be nice.

Measure resistance to ground from these locations:
Pin#7 on the smaller chip (AT-9J?)
Pin#13 on the larger chip (BD-9J?)
