| After installing my new Crescendo/PCI processor upgrade in a Power Tower Pro, I can hear the boot chime when I turn the computer on, but the video display never comes up. | May-12-09 |
| Some PowerTower Pros have a second, very different motherboard design. The problematic version of the motherboard appears to be very rare, based on Sonnet's sales history and the number of related calls.
You can identify the problematic motherboard by the part number. The part number is "silkscreened" onto the motherboard in white ink, like all the other markings on the board, and is located along the edge of the motherboard when you open the case and look directly at it (see below). The part number on the problematic system is PCC-5000-0141-01.
Sonnet has been unable to resolve this issue; Crescendo/PCI processor upgrade cards are incompatible in this one, specific instance. If you already purchased a Crescendo/PCI card and your computer has the motherboard described, return the product to the place you purchased the card and request a refund.

| After installing a Crescendo/ PCI G4 700 or 800 MHz upgrade, I opened Apple System Profiler and it is reporting the processor type as unknown and the speed as 450 MHz. | May-12-09 |
| The G4 chips used to achieve the speeds of these processors were created long after Apple created the ROM\u8217 s that are used in those vintage machines. In addition, Apple System Profiler (ASP) has never been very good at reading non-Apple engineered processors in OS\u8217 s prior to Mac OS X. The ASP calculates the 450 MHz speed using multipliers and the logic board bus speeds known at the time it was created. The chips on these upgrades have a maximum multiplier of 16x. But, Apple System Profiler does not recognize this advancement.
For OS\u8217 s prior to Mac OS X, the Sonnet software installs a utility called Metronome. This utility can be found under the Apple menu after installation. Metronome will give complete and accurate specs of the processor that is installed in your machine. If you are running a supported version of Mac OS X, and have installed the latest Sonnet X Tune-Up software, you will see that Apple System Profiler reports the processor type and speed correctly. |
