/proc/cpuinfo oops!

dear all

i ve got a fujitsu-siemens Amilo A laptop with an Athlon64 3700+

i am running fedora core 1 - i386 and not the x86_64 version as i was afraid of incompatibilities, with kernel version 2.4.22-1.2199.nptl

well my problem is that my /proc/cpuinfo shows:

processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 4
model name : AMD Athlon(tm) 64 Processor 3700+
stepping : 10
cpu MHz : 798.255
cache size : 1024 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 mca cmov pat pse36 clflush
mmx fxsr sse sse2 syscall mmxext lm 3dnowext 3dnow
bogomips : 1592.52

an athlon64 3700+ should run more than 798.255 MHz even in a 32 - bit linux version, am i correct or am i missing something crucial...
in addition i dont think that i have something running that could decreases my cpu speed
(anyway i saw the /proc/cpuinfo at 798.255 when my laptop was connected to a power source without the battery installed)

would somebody enlighten me what might be going wrong? i mean its such a shame to have a processor like this and not take advantage of it...

thanks for your help

You have cpuspeed running... It slows the CPU down when the load is light, to lower the heat produced and the battery consumption. Run something that takes a lot of processing power, and check /proc/cpuinfo while it's running. It should show that the speed is greater to fulfull the need.

If you want to run the cpu at full speed, run the command "kill -USR1 $(pidof cpuspeed)" as root.

well i did a ps -A (as root) and there is nothing that looks like cpuspeed
(is it called cpuspeed or does it have a shorter name?)

if cpuspeed is not the case, any other ideas?
