Hi,


 



This 
might be a dumb question, but just becasue you have 
hyperthreading,



should 
the system show more than 1 cpu?


 



Thanks,


 



Néstor

Also,

  problem!!

  
 


  
Hello,

Supermicro P8SCi 
  Motherboard
Intel Pentium 4 630 CPU (3.0 Ghz, 2 MB L2, Hyperthreading, 800 Mhz FSB)
1 GB DDRII 533 Mhz RAM 
  Non-ECC

Using RHEL 4 with 2.6.9-11.EL 
  kernel
when i run
#cat /proc/cpuinfo 
it shows only 1 processor 
  

seems my Hyperthreading is not 
  working,but its is enabled from BIOS.

For what it's worth, I have a system that uses
hyperthreading (Fedora 
Core 5) and top shows two cpu's.
