I have an older Dell Latitude D600 with a Pentium M 1400 MHz processor. A
couple years ago it suffered a BIOS melt down and while the system still
works, the battery will not charge, nor be recognized and the system does
not seem to want to run at full speed. Right now, cat /proc/cpu show the
system is running at 1400 MHz, but the system does NOT act that way.
I have checked with various programs and they show the same 1400 MHz. I
installed Windows XP and Windows 7 and both say the system is running at
600 MHz. I installed SiSoft Sandra and had it benchmark the processor and
it reported 600 MHz.
My question is, are there are programs I can run in Linux that will
actually test the speed of the processor, not just report whatever cat
/proc/cpu is showing? I have cpufreq running and it keeps the processor at
1400 while in linux, but I want to know if that is what the system is
really running at as I highly doubt it. I would believe it is 600. In
windows I had a small program that forced the processor to run at 1400 and
there was an obvious speed difference. In linux, it makes no difference
between 600 and 1400.
Any thoughts?
