FWIW, it seems pretty safe to turn ACC on using the 703 bios with a PhII. I've been playing with it for a few hours and haven't had to move the jumper yet...:up: (much better than 603 bios!)
Here are the things I've noticed so far:
1) It does screw up the individual core temp display in AOD 2.1.4 (and HWMonitor), but the TIMPIN1 still works so you'll have an idea of the CPU temp...
2) Unlike the 9950 which liked positive numbers (+4/+6) the PhII likes negative numbers better (-4/-6). I started off raising the ACC and went all the way up to +8, but I had much better luck on the negative side. The side benefit of that was that even at higher V's the temps stayed lower (of course thats assuming TIMPIN1 is reliable)....
These are very preliminary results, and ACC is just as confusing as it was using the 9950 but at least it's safe to play with again... ;)
Heres a SS of what I have so far.

Actual speed is 3.85, not sure why AOD shows current speed as 3.71. I can only assume Bios still needs a little more work... :D
BTW, I'm running 64bit Windows7 now, so take that into consideration as far as odd results are concerned. It runs pretty stable so I doubt that has anything to do with the wierd temp/speed results...
