Vipul, We can try to 'calibrate' the vt1211 reading. With an idle system, read the raw c7 and vt1211 temp values: cat /sys/devices/platform/vt1211*/temp?_input cpuid -r (from http://etallen.com/cpuid.html) Do the same with a busy system running cpuburn or some other stress program and send the outputs to the list. ...juerg On Thu, Apr 30, 2009 at 9:49 PM, Vipul Patel <vipul.mca.08 at gmail.com> wrote: > Hi, > > Motherbord= Portwell PPAP-2020VL > > stress:~ # cat /proc/cpuinfo > processor?????? : 0 > vendor_id?????? : CentaurHauls > cpu family????? : 6 > model?????????? : 13 > model name????? : VIA C7 Processor 1500MHz > stepping??????? : 0 > cpu MHz???????? : 798.055 > cache size????? : 128 KB > fdiv_bug??????? : no > hlt_bug???????? : no > f00f_bug??????? : no > coma_bug??????? : no > fpu???????????? : yes > fpu_exception?? : yes > cpuid level???? : 1 > wp????????????? : yes > flags?????????? : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge cmov > pat clflush acpi mmx fxsr sse sse2 tm nx up pni est tm2 xtpr rng rng_en ace > ace_en ace2 ace2_en phe phe_en pmm pmm_en > bogomips??????? : 1598.25 > clflush size??? : 64 > > > stress:/tmp/cpuid-20060917 # ./cpuid > CPU: > ?? vendor_id = "CentaurHauls" > ?? version information (1/eax): > ????? processor type? = primary processor (0) > ????? family????????? = Intel Pentium Pro/II/III/Celeron, AMD Athlon/Duron, > Cyrix M2, VIA C3 (6) > ????? model?????????? = 0xd (13) > ????? stepping id???? = 0x0 (0) > ????? extended family = 0x0 (0) > ????? extended model? = 0x0 (0) > ?????
