72 The Crescendo/Encore installer hangs, or crashes the system; occurs most often when run from the Sonnet installer CD.May-12-09
76 Which current Encore/ST G4 processor upgrades include a pre-attached heat sink?May-12-09
All models in the Encore/ST G4 line made today, except for those with a part number that starts with SG4-C, include a pre-attached heat sink. Products with a part number that starts with SG4-C are for use only in Power Mac G4 Cube, and do not include a pre-attached heat sink.
 
77 I purchased an Encore/ST G4 processor upgrade that is just a card; is it less reliable than one with a pre-attached heat sink?May-12-09
When installed correctly, the Encore/ST G4 card reusing the Apple heat sink is just as reliable as the more recent Encore/ST G4 card with a pre-attached Sonnet heat sink. Sonnet chose to pre-attach a heat sink to Encore/ST G4 upgrades (except for those with a part number that starts with SG4-C) because we determined that some users did not properly attach the Apple heat sink and clips, and we wanted to make the installation process easier.

204 Mac OS 10.5 "Leopard" shuts down a few seconds into booting after a new installation of the OS.May-07-09
This problem has nothing to do with our processor upgrade being in the machine or with the firmware update that was done beforehand.

It has everything to do with how 10.5 was installed. Doing the 10.5 install as a simple "Upgrade" rather than using some of the other options like Archive and Install or Erase and Install.

When you do a straight upgrade, the installer just overwrites the old 10.4 System folder and that can leave some incompatible kernel extensions lurking in the new 10.5 folder whose response to that is to shut down on boot if it encounters something it doesn't like. So you need to do an Archive and Install of 10.5. This will create a new System folder, migrate your various user settings but it won't migrate any outdated stuff to the new folder.
