Since it is quite noisy I allowed cpuspeed at startup and this improved=20 the situation a little bit. Still cpufreq-info (see details above -in french, but you can guess) gives hardware limits : 2.10 GHz - 2.80 GHz Is there any hope to go below 2.10 GHz and if yes, how ? Thanks, Niels cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Celeron(R) CPU 2.80GHz stepping : 9 cpu MHz : 2100.000 cache size : 128 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 mtrr pge mca cmov=20 pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid xtpr bogomips : 5589.50 cpufreq-info cpufrequtils 0.4: cpufreq-info (C) Dominik Brodowski 2004 Veuillez rapportez les erreurs et les bogues =E0 linux@brodo.de, s'il vous = plait. analyse du CPU 0 : pilote : p4-clockmod CPUs qui doivent changer de fr=E9quences en m=EAme temps : 0 limitation mat=E9rielle : 2.10 GHz - 2.80 GHz plage de fr=E9quence : 2.10 GHz, 2.45 GHz, 2.80 GHz r=E9gulateurs disponibles : userspace, performance tactique actuelle : la fr=E9quence doit =EAtre comprise entre 2.10 GHz e= t=20 2.80 GHz.
