Unhappy please help guys, wrong cpu speed shown with a regular non-mobile cpu !! : (


i installed fedora core 3 on and older pII 333 MHz (Klamath) it has 96 mb of ram and a 15gb hdd. it's and old compaq deskpro 4000. i made a clean install, no graphical systems installed. i was going to make a little server out of it. bios detects the cpu speed correctly. but cat /proc/sysinfo shows the following:

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 3
model name : Pentium II (Klamath)
stepping : 4
cpu MHz : 133.237
cache size : 512 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 mmx
bogomips : 260.09

and dmesg | grep MHz says:

Detected 133.237 MHz processor.
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx

but it is supposed to be 333 mhz cpu, and it is not a mobile processor or smt

it has a a onboard lan card also, which is capable on 100M FD, but i'm not even able to use all that because at 40%-45% of network load the cpu is used all up and it seems like it really is running on 133 mhz...

does anyone have the same problem, or knows how to fix smt like that?

maybe this is useful for you all also who know the aswer:

00:00.0 Host bridge: Intel Corp. 440LX/EX - 82443LX/EX Host bridge (rev 03)

00:14.3 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ACPI (rev 01)

please help, could it be the fault of a 2.6 kernel? should i use fc1 with 2.4 kernel?

ok, problem solved. it was an 300 mhz processor, but was oveclocked to 333, and bios reported it to be 333 also, but as it turned out it was 133 really, so set the jumpers back to normal, 300 mhz operation, and it works fine now and detects the speed correctly
