Version 2.0.5 from
here is the most recentest, all-singingest and all dancingest. You need both control panel and extension, and, if you are running an OS earlier than 8.1 ⚠, the LibMoto extension also. Go into the Extensions folder, and insert a single space in the MAXpowr extension's name before the 'M', so that the extension loads early (but not earlier than EM Extension) at startup. Leave the control panel in its alphabetical order. This is all to be done
before you exchange the daughter cards.
Having installed the MAXpowr card, you must press the CUDA switch. I haven't done this in a 7300, only in 8100, 8500 and 9500. Note the position of the CUDA on the board, because you may have to peer between the fins of the card's heatsink when the card is in place. Be sure to seat it properly. It 'snaps' into place when you press hard enough. Use a plastic outlet tube from a can of compressed air to winkle between the fins, if you need to, and hold the button in for at least 20sec. Continue reassembly, and then restart the Mac. You can customize the settings of the control panel through the Apple::Control Panels route. One worthwhile setting is to have the original soldered-in L2 cache set to 'off', not 'off if ...'.
There is a suite of utilities from NewerTech: Cache-22, Clockometer, Gauge PRO and RAMometer, which enable you to test the performance of your upgraded system. If you are presently at the point of having trouble with the process after installation of the G3 card, but did not install the software before you removed the 604e card, you will find it least frustrating to return to taws, ie put the 604e back in, and proceed from there.
