Hi
Any idea why this happens? FWIW, processor is PPC 7455 v3.3, and xbench scores are around 98-100. Energy Saver is at Highest Processor Speed. (xbench drops to around 72-75 when Proc.Speed is Reduced, so I suspect the processor is really running at 867 MHz...)
About this Mac shows 867 MHz, all other tools (incl. Reggie) show 667 MHz.
Please enlighten

I've got a 667MHz on reduced processor speed and my X-Bench is around 72.
What does the 667MHz get reduced to?

ALL of the Titaniums above 667Mhz show that they run at 667Mhz on "Reduced Processor Performance."
Including the 1Ghz.
The easiest way to see it is the reduce the processor performance under Energy Saver (System Prefs) and then go to Options and turn it down.
Boot out of OS X and back into OS 9.
Under OS 9 take a look at your System Prefs under the Apple Menu. It will show you right there "666Mhz" or in some cases, "667Mhz."

That's interesting. My GHz TiBook get 98-100 at 1 GHz.

Energy saving: Reduced Performance translates to...
Ti 667: Speed remains the same, only L3 Cache is turned off.
Ti 800, Ti 867, Ti 1000: Speed drops to 667 MHz and L3 cache is turned off.
Again, does anyone know why my clock speed is misreported, even though no Energy Saving is in effect?
