W/ my 9500, 2.3GHz (209x11) was unstable with all stock voltages. It was also unstable w/ CPU voltage @ +0.02V. Finally I got it stable by increasing CPU voltage +0.05V, NB + 0.10V, and increasing HT voltage from 1.20V to 1.25V.

I've now tried lowering just the CPU voltage, and it seems to be stable at stock (1.24V). Prime 95 has been running for just about 1.5 hours.

W/ the stock HT/NB speed, 220x10 would not even boot, so that is why I am thinking that it was just the HT/NB voltages that needed adjusting.
You're right about the NB voltage, but I haven't had to mess with the HT. I Fold@Home at 2.5GHz (239 x 10.5) and leave the HT multi @ 9x without issue. Vcore is +.15v & NB is +.10v.
