cpuinfo not showing right processor speed I believe
| Posted by hostcadet, 12-31-2009, 01:26 AM |
| I have two hp servers with Dual-Core AMD Opteron(tm) Processor 2220
I am for sure they both have the same processors in the machines.
They are hp servers dl385. When doing cat /proc/cpuinfo on machine 1.
cpu MHz : 2800.000
Now on the second server the cat /proc/cpuinfo results in.
cpu MHz : 1000.000
I did some looking and I don't believe that speed processor is even
available in the HP servers. So why would it be incorrect and also
is there a way to fix this. Should I try a reinstall would that maybe
help?
Thanks in advance!!

| Which linux OS they use? Did you check if they use different kernel versions? Try to install the latest kernel available with your linux distro. and see the difference again....

| When the CPU is used less, the % frequency will drop to lower the power usage and is called Frequency scaling. You can turn it off from BIOS and will see the correct cpu MHz under /proc/cpuinfo.
You can check the actual cpu MHz using the command
OR
check the cpu information under the directory

| Hi,
Have you tried turning off cpuspeed?

| I have centos. I have tried turning that off in the bios no change. I have reinstalled with both 32 and 64 bit and the cat /proc/cpuinfo shows the wrong thing.
If I do the dmesg that shows correctly here is the part after bringing up the cpu's i can see its 2.8 but the cat /proc/cpuinfo shows 1.0 very weird.
Brought up 4 CPUs
testing NMI watchdog ... OK.
time.c: Using 14.318180 MHz WALL HPET GTOD HPET timer.
time.c: Detected 2800.460 MHz processor.
when looking at the max freq under /sys/devices/system/cpu/
it also shows 2800000
So I guess there won't be any reduced performance I wouldn't think.
