| 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 following the instructions and installing both the Crescendo/PCI G4 700 or 800 MHz upgrade card and its included software into my computer, the video is distorted and my cursor is a rectangular block that cannot move more than halfway down the screen. | Jun-23-09 |
| Some Mac clones andPower Macintosh computers do not have onboard video, but instead use a separate video card (ATI XClaim 3D, ATI Mach 64, IX Micro Twin Turbo, or IX Micro Ultimate Rez) installed in a PCI slot. These cards are anywhere from 4-6 years old and have not had software or firmware updates in several years. The lack of updated firmware and software, when combined with the G4 chips used on these high-speed upgrades, result in this instability.
Solution 1: If your system is running Mac OS 9.x, turn off the video card's extensions in the Extensions Manager Control Panel.
Solution 2: Replace the video card with one that has current software/firmware or with an older video card compatible with these systems such as the ATI Radeon Mac edition and the ATI Radeon 7000 Mac edition. |
