Does my L7300@1.4Ghz CPU run at 1.6Ghz? (pics)

I just downloaded the CPU-Z app to test whether or not my computer would be able to run OSX.
And when I started the program I noticed that it was, supposedly, running at 1.6Ghz
And the weird thing is that the power settings where at "Maximum Battery life"
And when I change to "Maximum perfomance" it goes down to 1.4Ghz
Is the CPU realy running at 1.6Ghz?

your program is just not updated to match multipliers or something. Do you have the latest version?

yeah, just got it from the site:

under "download the latest version"

It's still out of date. It's not recognizing the lower FSB, the speed is supposed to be 800 iirc, 8x100.
Interesting possibilities come to mind though. Looks like the multiplier's not locked as tightly as it once was, so it may be possible to actually get 8x200 (not the case here of course).

The Intel Processor Frequency ID Utility is likely to be able to tell you what is happening with your CPU.

Yeah it must be the FSB that it is not registering.
but the software is quite new, it's from 03/29/2008
The intel software however is quite old, from 2004
it's no use on vista.

The only SW I can find that gets this right on Santa Rosa chips is the Intel Thermal Analysis Tool. MOBmeter also gets it right in certain modes.

It is just Dynamic Overclocking of one core when the other core is not used.
It is a new feature of Santa Rosa platform, nothing to worry about.

No it's not. 1.8 and 2GHz CPUs also report 1.6GHz with CPUID in battery mode. It is an error. These chips drop down to 8x multiplier and 100MHz bus (quad pumped). Most frequency tools miss the bus speed drop.

the newest RMclock reports correctly on FSB changes.

Actually, you are wrong. Santa Rosa platform only drops to 400MHz FSB in SuperLFM mode (aka C4 enhanced State). Normal Power Manager like Windows and Lenovo do support this state but they don't let this state last long when you starts using your machine. If you want to keep the CPU at this state, you need a real clock manager like RMClock.
