> So what are my options on the slow single G4-800 on a QS2002? As far as I know, every QS2002 processor card should work. I personally would grab anything that is low priced and a Dual processor for 133 MHz system buses. That is: * Dual-533 MHz from Digital Audio * Dual-800 MHz from Quicksilver * Dual-1 GHz from Quicksilver 2002 You cannot use a processor from an MDD or FW800, they are incompatible. You could use a Dual-450 or Dual-500 from a Gigabit Ethernet, but you'd have to move resistors, since these are for 100 MHz system buses. Examples: 4.5 × 100 MHz = 450 MHz 3.5 × 133 MHz = 465 MHz or 5.0 × 100 MHz = 500 MHz 4.0 × 133 MHz = 533 MHz You can see why the Digital Audio has a Dual-533 MHz instead of a Dual-500 MHz processor – the 133 MHz system bus. (Re)move the resistors like described in this link: http://power-mac-g4.com/g4clockup.html In the table “G4 JUMPER CHART”, set the Multiplicator CCU so that it gives the correct CPU speed for a 133 MHz bus. A CPU upgrade card from OWC, Sonnect, Newer Technology, FastMac, Giga Designs or PowerLogix is also a good option, but I recommend at least a Single-1.2 GHz for decent performance. These cards are often quite expensive, even used ones.
