[s e t h]

ok pin7 to ground via a 50vr works perfectly for vgpu as far as i can tell.
start at 50k and decrease resistence to increase vgpu
core now does 650 with some artifacts in canyon and 625mhz artifact free.
all the +- 1.30volt measuring points in post#1 now read 1.38 idle and 1.40 when loaded.

i hope this is the right datasheet on the LM358: http://www.national.com/ds/LM/LM158.pdf
the RT9214 is usually pin6 to ground by what i can find on the web.
anybody got any tips on the memory mod before i proceed further.

here's a score at 650/700

and a bad pic of the mod :P
