How to know FBS ? else than ACPI (which reports 133Mhz) ?

Then I suppose that any RAM module above 133 Mhz will fit , does it ? or x2 since it is DDR RAM

Athlon XP Mobile (1400+ to 2×00+)

What does this CPU infos mean ?

So it says “Max Speed 1533 Mhz”.

My processor is Mobile Athlon XP 1800+ (that's scaled on performances of Intel 1800Mhz)

But its frequence, seen by linux, is 927 Mhz (cat /proc/cpuinfo)…

Even worse, in Windows XP, it says around 350 :o)…

The CPU Frequency is variable and depend on resources usages… how to tune this ?

Plus, my processor, without cpu scaling, heats to 95ḞC when used to 100% for quite a long time…

And then the computer turn off because of such high temperatures.

I didn't experience that with Windows, though I'm not sure I used the processor at 100% during a long time.

monitor that with gkrellm My fan use to start as soon as video is decoded or on heavy processes like compilations , Java , flash player , Emulators … but it often say silent around 50 DC…

What would I learn from gkrellm ?

I already know that the temperature goes rapidly to 85ḞC and then slowly goes up and up.

The fan is, from what I hear, at maximum speed (reminder : all this concerns when the cpu is used to 100% for a long time).
