Can somebody confirm this given information is valid and correct ?
I visited this: http://www.intel.com/products/processor/pentium_D/index.htm
Since all processors are dual core, I can imagine there's something wrong with the kernel information guessed for my CPU (this is not my computer, I'm at work now).
thanks in advance. |

Melikes Intel's clear well-thought-out explanation of multicore processors... | Quote: | | Dual-core processing allows for true simultaneous computing so multiple users can access and enjoy the same PC, even from different rooms with a home network and networked devices. |
riiiiight, that's never been possible without multiple processors before... that's a hardware limitation, not a windows one... 
But yeah, there's something wrong with your cpuinfo. Specifically, if it's dual core, it should be showing TWO CPUS. Have you enabled SMP?

Hi,
Nopes, SMP is not enabled... but I don't think this computer has 2CPU or 1CPU dual-core, in fact.

You have to enable smp in the kernel config to see both CPU cores. I dont know if this switch has an impact on cpuinfo too.
