Odd /proc/cpuinfo
So I never paid attention to this since I always assumed the system will do The Right Thing (TM), however while going through servers today, I came across this discrepancy and was hoping someone here could help me figure out what's going on. While 'cat'ing /proc/cpuinfo I see this (other information removed): vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Pentium(R) 4 CPU 3.40GHz stepping: 10 cpu MHz : 2400.000 cache size : 2048 KB Someone please explain to me how the CPU is a 3.4GHz CPU (which I've verified by reading it right off of the top of the processor) and yet two lines down it says that it's 2400.000 MHz (or 2.4GHz) What happened with the missing 1GHz? The second CPU reports the same thing. Is this a motherboard issue? Possibly not configured right? If so, boy do I feel stupid considering this machine has been in production for a long time and no one's ever noticed. Comments?

If you have cpuspeed or cpu-freq running, it will scale the speed of the CPU based on workload. If the machine's busy, the CPU will run faster, if not... -- - Rick Stevens, Systems Engineer ri...@nerd.com - - AIM/Skype: therps2ICQ: 22643734Yahoo: origrps2 - -- -- -- users mailing list users@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
