I have run my early 05 17in at 2.08 or 2.17. Was unstable. I have a DLSD. It has a usual PPC7447 but totally different motherboard config. It has resistor settings for 200MHz bus speed on front of the board according to the schematics. Your Screens shot shows the busses at 133mhz. I wonder if this is an error. I see the PLL config resistors near the CPU. Will check the schematic to see what multiplier it corresponds to. If the resistors are at the stock 10x bus speedconfig, the bus has been raised. edit: bus is clocked. Two pins set to 0 in PLL config. Through process of elimination, that leaves 10x multiplier. 10 x 200 is 2ghz. Multiplier All multiplier settings appear to be 10K-Ohm ..................0...........1 PLL0 -> R3721+R3720 PLL1 -> R3723+R3722 PLL2 -> R3725+R3724 PLL3 -> R3727+R3726 PLL4 -> R3729+R3728 PLL5 -> R3731+R3730 NOTE: PLL5 is only for diagnostic use. Do not set it to anything other than 0. The PowerBook will not function properly with PLL5 set to 1. Bus All bus settings appear to be 10K-Ohm ....................0...........1 BOM0 -> R2305+R2304 BOM1 -> R2307+R2306 BOM2 -> R2309+R2308 BOM3 -> R2311+R2310 When the resistor on the 0 side of a BOM jumped, the BOM is set to 0. When the resistor on the 1 side of a BOM jumped, the BOM is set to 1. If both the 0 side and 1 side is jumped the PowerBook will not function properly. Voltage All voltage pins are 470K-Ohm. ...............0..........1 D0 -> R3988+R3989 D1 -> R3986+R3987 D2 -> R3984+R3985 D3 -> R3982+R3983 D4 -> R3980+R3981 When only the resistor on the left of the chart is jumped, the pin is set to 0. When the only resistor on the right side of the chart is jumped, the pin is set to 1. Example: D4 is set to 0 if only R3980 is jumped. D4 is set to 1 if only R398 is jumped.
