http://ubuntuforums.org – Hi, im using an Intel Core 2 Quad (Q8400 @ 2.66ghz) and when i use cat /proc/cpuinfo all informatino is correct except my clock speeds, heres my output: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 23 model name : Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66GHz stepping : 10 cpu MHz : 2003.000 cache size : 2048 KB physical id : 0 siblings : 4 core id : 0 cpu cores : 4 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss (Hardware)

I would like to understand how many number of CPUs and cores do I have on my server based on following out put..

Quote:

[root@xyz ~]# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 26 model name : Intel(R) Xeon(R) CPU X5570 @ 2.93GHz stepping : 5 cpu MHz : 1596.000 cache size : 8192 KB physical id : 0 siblings : 8 core id : 0 cpu core

Hi!

This is probably a stupid question, but here goes. After updating to F12 with preupgrade, i started noticing that my two cpu processorscaling applets in gnome acted strange. It turned out to not be able to modify CPU1 at all. /proc/cpuinfo gives me

vendor_id : GenuineIntel cpu family : 6 model : 23

I have done a sched_setaffinity test in Linux in a server with 1 socket ,4 cores , the following /proc/cpuinfo showes the cpu information :

processor : 0 model name : Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66GHz cache size : 2048 KB physical id : 0 siblings : 4 cpu cores : 4

processor : 1 model name : Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66GH

processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 23 model name : Intel(R) Core(TM)2 Quad CPU Q9450 @ 2.66GHz stepping : 7 cpu MHz : 2659.855 cache size : 6144 KB physical id : 0 siblings : 4 core id : 0 cpu cores : 4 apicid ...

Would you please explain me what kind of differences between these two CPUs have:

1) processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU E5345 @ 2.33GHz stepping : 11 cpu MHz : 2324.000 cache size : 4096 KB physical id : 0 siblings : 4 core id : 0 cpu cores : 4 fp

Hi Guys, I have a AMD Semperon LE-1300 processor. Linux is saying I only have 1.006 GHz when my processor is capable of 2.3 GHz. HOW DO I FIX THIS!?!?!?

I used the command cat /proc/cpuinfo to see if it was an application that was manipulating the speed of my processor. and I got this:

Code: processor        : 0
