similar to: sempron 2500+ running at 1044 cpu speed.

what is the correct way to set an AMD64 CPU into performance mode at boot time? I have tried doing service network cpuspeed start, then killall -SIGUSR1 cpuspeed and this works but I cant get it working this way at boot. I have set chkconfig cpuspeed on but that didnt seem to help. I just want this particular machine to boot in performance mode and stay there. Jerry

Chris, I have a compaq AMD r4000 x86_64. grabbing the latest kernel and compiling it fixed my clock skew. I have not had any slow disk issues. again the kernel may help doing the command: killall -SIGUSR1 cpuspeed makes the CPU run faster. Hope that helps.

It appears as cpuspeed is not running on my centos 5 box(s). One is a biostar motherboard Am2 6400+ the other is Asus am2 4800+. If I do "service cpuspeed stop" it says OK, If I do a "service cpuspeed start" is says OK. However at no time is cpuspeed running. /proc/cpuinfo only shows the cpu running at 1000 Mhz. If I manually run "cpuspeed -C & " I now have

Hi all, Is it ok to use the i686 kernel in an AMD Sempron or should I be using another? regards tom

We are using CentOS-4.3 (x86_64) with Opteron servers, and noticed a problem with cpuspeed: If we reboot by doing "# reboot" or similar from a shell, the boot will hang not long after cpuspeed starts. The machine freezes: ctrl-alt-del doesn't work, and only pressing the reset button or a power cycle will restart the machine. If we reboot from power-up or by pressing the reset

Hi all, I think I've spotted a few stupidities (bugs) in the current version of kernel-utils (kernel-utils-2.4-13.1.80). I'm sure these are all propagated from upstream, but I hope someone could have a quick look to verify this and see if we either can push complaints upwards, or provide local fixes. The kernel-utils package provides several 'kernel-type' functions -

Hi to the list, I am trying to find a way to painlessly move structured data back and forth between R and Matlab (also Octave). For this purpose I found the R.matlab package great help. I wish to use a Matlab -v6 MAT file as an intermediary format, because it is well read by both Matlab and Octave. It is also well read by 'readMat' function in R.matlab package, but that is where I run

After upgrade my laptop, I discovered a low performance on it. The laptop is a 2,73GHz Intel centrino and from some kernels versions to now, it had a good performance, the cpu scaling worked fine. Now, I discover that forcing in /etc/sysconfig/cpuspeed the governors and/or max/min speeds, it don't want to run more quickly. The laptop boots fine with the correct speed (usual speed), but when

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi I''m currently using xen-3.0.2-testing on several servers. But when xen 3.0.3 was announced I wanted to try it, of course it should have several iprovements and bugfixes, etc. I did the same steps I was previously done in order to compile xen-3.0.2, and in fact xen compiled and installed very cleanly. I created my initrd image and then I

Hey, folks, Sometimes my workstation bogs down... slows to a crawl. Using gkrellm, it's obvious the CPU is the laggard. The top utility confirms: the load average gets up over 4 at times. But this occurs when cpu stepping pegs the speed at 600MHz. This processor is capable of 1.5GHz and when it's allowed to run at that speed, the load average is under 2, which is fine. So the

One problem I've discovered in cpuspeed is that there are drivers missing: # cd /lib/modules/2.6.18-194.8.1.el5/kernel/drivers/cpufreq # ll total 72 -rwxr--r-- 1 root root 14408 Jul 1 21:40 cpufreq_conservative.ko -rwxr--r-- 1 root root 16168 Jul 1 21:40 cpufreq_ondemand.ko -rwxr--r-- 1 root root 7624 Jul 1 21:40 cpufreq_powersave.ko -rwxr--r-- 1 root root 12524 Jul 1 21:40

After a couple hours last night.... doing a "killall -SIGUSR1 cpuspeed" bumps up the /proc/cpuinfo information for cpu mhz to 2393 Mhz. I did notice a little increase after that. However, the machine is still sluggish. I did a "hdparm -c 1 /dev/hda" but really did not notice any difference. I tried to download fglrx64_6_8_0_8.16.20-1.x86_64.rpm from ati (also 8.20.8) and get

Hi, cpuspeed did not start on all my systems. CentOS 5.4 x86_64 /etc/init.d/cpuspeed start (nothing happen) Something is missing ? Thanks in advance for any idea.

On a new server's CentOS5 install, with nothing in the way of applications running yet, I noticed that the load average was sitting between 2 and 5 all the time, even though top told me CPU was 100% idle. Eventually I found that stopping the "cpuspeed" subsystem allowed the load average to drop down to near zero, as I would expect it to be. I have the default

Hi, we bought some machines with 2 x quad core Xeon E5405 processors and installed centos 5.3 on them. My problem is that I can't get the cpuspeed service to work. No driver seems to claim responsibility for the throttling and the fallback "modprobe acpi_cpufreq" in the cpuspeed init script just yields a "No such device" message. According to the acpi information the

In older version of centos there was cpuspeed -d running that controlled current speed. In centos 5 it is set for on demand and cpuspeed is not running. I can startup cpuspeed and send it a signal SIGUSR1 to go full speed. This works. However, What is the correct or prefered method to control the cpuspeed in centos 5? THere are times when I want to tell the machine to go full speed and

I've been playing and comparing frequency scaling between AMD and Intel CPUs yesterday and there seem to be great differences between AMD and Intel and some gotchas. This is all on CentOS 5.2 with latest Xen kernels (which are supposed to be powersaving-enabled since 5.2). AMD: It seems once I get the AMD CPU to use the ondemand governor it works very well and very efficiently. But this

In the old centos 4 we had cpuspeed and we could send a SIGUSR1 to it so the CPU would run at max speed. In centos 5 cpuspeed is not running. (although running with cpuspeed -C will go full speed) what is the correct way now in centos 5 to on the fly say run at full speed then sometime later tell it to drop back down? I have no process to signal any more. Jerry

I have a kickstart file that I am using to install multiple machines. If I install with no %post script, everything runs great. When I add the following %post section, if fails.
