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.
 
169 May I discard my original CPU after installing Sonnet's upgrade cards? May-07-09
171 The speed indicated on the G3 or G4 chip on my Sonnet processor upgrade doesn't seem to match the speed of the upgrade I purchased. What's the story?May-07-09

176 Sonnet OS X Installer InstructionsMay-07-09
204 Mac OS 10.5 "Leopard" shuts down a few seconds into booting after a new installation of the OS.May-07-09
218 The computer's standard startup process takes noticeably longer after upgrading to any Mac OS 9.x system from Mac OS 8.6 or earlier.May-12-09
This is not a malfunction and is not related in any way to Sonnet upgrade products; this is the result of an additional Mac OS 9.x startup process that did not occur during startup in earlier Mac OS versions. There is a new "hidden" Mac OS 9.x feature called Startup Memory Tests in the Memory Control Panel, which defaults to the "On" setting. This adds time during a startup or restart, as all of the RAM installed in the computer is checked.

This issue affects any machine running OS 9.x (OS X status is unknown as of this writing), with or without upgrades installed. The more RAM installed, the longer the test. (Note that a Mac upgraded with a Sonnet G3 or G4 processor card gets through this process much faster than a "stock" machine.)

Since this is not a malfunction, no solution is required. However, since RAM seldom fails after the first few days of regular use, you may turn this test off if a faster startup cycle is desired. To access this feature you must hold down the Command key and the Option key WHILE opening the Memory Control Panel. When the control panel opens, you will see a setting at the bottom of the control panel. Click the Startup Memory Tests' Off button, then close the Memory Control Panel. Be aware that from now on, when you start up or restart your computer, the Mac OS will NOT check your RAM. If in the future you suspect a memory problem and want to check your RAM, you will need to repeat this procedure and turn the Startup Memory Tests back on.
