I cant regulate voltage (athough I can set VID register and load atxp1 module), but this chip can regulate FSB The ATXP5/2 doesn't seem to have the VID in/outputs. But they have the FID (multiplier) and GPIO registers. FID changing has normally no effect during runtime, because it's only used during power-up (at least on the AMD cpu, not sure about the SiS chipset). > Near this chip is DIP switch to adjust FSB manually. > It has 24 legs total. > > DIP SW combinations: > > 133 166 [OFF] [OFF] [ON] [ON] > 100 133 [ON] [ON] [ON] [OFF] > 133 100 [OFF] [ON] [ON] [OFF] > 133 133 [OFF] [ON] [OFF] [OFF] > 100 100 [OFF] [OFF] [OFF] [OFF > > So I think ATXP2 can adjust FSB and MEM frq somehow. Yes, maybe they are using the GPIO pins, but then the switches must be in a specific position so the GPIO outputs are getting priority... Can you please run i2cdump on the ATXP2 ? Bye, Sebastian
