| 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. |
