I plan to upgrade my AmiloA CPU, which is the fastest CPU our MB can support ?
AXMD1900FVQ3C should be ok
2600+ seems to be highest in low consumtion serie

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).
