[opensuse] "My Computer" desktop application cpu details incorrect
Hi: I'm running opensuse 10.2 on AMD Athlon 64 X2 Dual Core Processor 3800+ using kernel Linux 2.6.20-rc5-git1-20070124145831-default x86_64. KDE 3.5.5 "release 45.2". Right after boot, "My Computer" desktop application shows what I think is the correct CPU speed: 2,000.00 MHz. "My Computer" seems to refresh itself. If I leave the window up, over time I see the speed change to 1,800.00 MHz, back to 2,000.00 MHz. Then finally, it changes permanently to 1,000.00 MHz. cat /proc/cpuinfo shows 2 CPUs, processor 0 and processor 1, and each CPU MHz 1000.000. So together that should be 2000.00 MHz. Output from cat /proc/cpuinfo follows: richard@linux:~> cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 75 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ stepping : 2 cpu MHz : 1000.000 cache size : 512 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm cr8_legacy bogomips : 2005.94 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp tm stc processor : 1 vendor_id : AuthenticAMD cpu family : 15 model : 75 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ stepping : 2 cpu MHz : 1000.000 cache size : 512 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm cr8_legacy bogomips : 2005.94 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp tm stc Is this a KDE Konqueror problem or something else?

If it is not running, kde->System->Desktop Applet->Kpowersave, right click on the taskbar icon and choose set active scheme->performance. If kpowersave is running you will have a little ac powercord in the taskbar. I experienced this same thing on an Athlon 64 2000Mhz, it is nothing more than acpi throttling the cpu to conserve power. If you left click the icon it will bring up a monitor window, then launch a couple of applications and watch the speed increase to meet demand.

Don't worry about your CPU. All modern CPUs (Athlon 64, Pentium 4, Core 2, ...) can enter power-saving features, which lowers their speed automatically when idle. If you put some heavy task on tham, they will run full-speed. There are utilities that can measure speed accurately (under Windows) in Real-Time, but I don't know such utilities under Linux. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hello all, A simple command is: watch -n 5 grep MHz /proc/cpuinfo or with powersaved running (in Alexey's case, it is running) watch -n 5 powersave -r KPowersave also shows real-time CPU speed, which it gets from powersaved. (Does powersaved use information from /proc?) The sysinfo KIO slave (which is 'My Computer') uses /proc directly. -- Regards, Aveek Bhattacharya IIT Bombay DITTISHAM (n.)

When not doing heavy work, modern CPUs reduce their speed to save power and that is exactly what you're seeing. So there's no need for worrying :) Philipp -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

[...] No, it is not totaled up, each processor will go to 2000 Mhz when they are at full throttle. In the KPowersave you can right click and tell kpowersave to set the scheme to performance and it will keep the cpus at full throttle.

The usage, "My Computer," "My Files," etc. seems puerile to me, especially to those of us who have more than one computer, or one at home and one at work, etc. It is what I would expect of MS, but I think it should go away on Linux. I always change it to "This Computer" in both OS's, and that's what I think it ought to be. --doug -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I change it to the computer name. I often use remote desktops and it helps to have a reminder about which computer I'm working on. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
