can cpu-z be wrong?

can cpu-z be wrong?

i purchased a t43 with what i was supposed to be a pentium m 760 but cpu-z is telling me i have a pentium m 755 which has same processor speed (2.0 ghz) but different FSB (400 vs. 533).

if cpu-z can't be wrong, IBM sold me a 755 (obviously a processor with a slower FSB) and charged me for a 760! if it can be wrong/inaccurate in this way, how can i verify the FSB speed of my unit?

Assuming you're running Windows you can run "dxdiag" (through the "Run" menu on the start menu) and on the first tab of that it should list Processor.
On mine it reads: "Intel(R) Core(TM)2 CPU T7200 @2.00GHz (2CPUs)"

There are also other programs to run, RightMark for example, has a utility that can underclock and otherwise manage your CPU in addition to simply identifying it.

 

You can also right-click on "My Computer" and go to Properties, and the dialog that comes up will tell you the exact same thing.

 

thanks for your response.

neither suggestion, however, gets me out of my bind because both tell me that my processor is a 2.0ghz but that doesn't clarify the key distinction (i.e. the FSB speed).

 

right, but again, this only gives me the processor speed. i really need something that will identify the processor type (which is why i tried CPU-Z) or something that can tell me the FSB speed for my system. that --i.e. the FSB-- is the only real difference between the 755 and 760.

 

Maybe check in Everest or Sandra? My guess is both will be reporting the same things you've already seen but maybe worth a try...

Try with Intel's own processor identificaion tool...
http://www.intel.com/support/processors/tools/piu/

It should list the model number of your processor.

 

thanks miner

i guess cpu-z can be wrong. according to the Intel tool, i do indeed have a 760. that's a relief, i was dreading having to resolve that conflict with IBM. thanks all

 

Yep, CPU-Z can be wrong. All it does is ask for a CPU id (which is basically just a number), and then look it up in its built-in table to find the specs. if that table is out of date (doesn't include a specific CPU), it may show wrong information.

 

You should also be able to find what processor you have in the BIOS, it should be listed somewhere.
