Server :: Frequency Scaling Not Working - Out Of 11 Steps Can Change To Only 2 Frequencies And Rest Fail To Work
Apr 23, 2011
I am using Intel Xeon X 3440 processor. The processor has 11 frequency steps to chose from. I have used cpufreq-selector for choosing a frequency and it worked fine. But, all of a sudden it stops working out of the 11 steps i can change to only 2 frequencies and rest fail to work. I am clueless as to why it stopped working suddenly.
I have the CPU frequency scaling applet in the panel and it worked fine when I had 8.10 but now that I'm using Karmic, I cant get it to work correctly!
It won't change the speed to what I tell it to. I click on a different speed and it does nothing.
The CPU spins too slowly and videos lag or it spins at full speed and overheats even though I have nothing open! I really need to be able to adjust it.
I have recently installed Ubuntu 11.04 on my PC with these configuration:CPU: AMD Athlon 7750 Black EditionRAM: 2GB 1066 MHzVGA: ATI Radeon HD 3200 (on AMD 780G)After I installed Natty Narwhal I felt that my CPU runs at the highest clock all the time (2.7GHz), even if I don't have any program run. I tried all settings for AMD Cool'n'Quiet from mainboard BIOS, but nothing's changed. I installed "CPU Frequency Scaling Monitor" to manually change CPU clock. It recognizes two clock for my CPU, 2.7GHz and 1.35Ghz plus 4 other options; Conservative, Ondemand, Performance and Powersave but the CPU indicator doesn't change on every option!
I am not entirely convinced that my CPU is actually changing frequency as it is meant to. It sometimes changes frequency, but most of the time it is stuck on 800MHz even when doing cpu intensive tasks. Here is information that may or may not be of help:
I am new to ubuntu. I have just one question, everytime I reboot my laptop the CPU Frequency Scaling Monitor goes back to "On Demand." Why is that and can I also set it so it stays on Performance.
I recently installed 10.04 and really like it so far, however I was wondering if it is possible to scale all hypertheading cores at once, currently I am using an applet for each and have to use several clicks to get into the desired powerstate.
I have read that with dual cores you will not have the option to go into different powerstates because it scales all cores at once, however the logical cores that show up with hyperthreading allow each to have a different power state, and will show up as different states if I use cpufreq-info in the terminal, so it seems like it is allowing it.
When I boot my machine (using a dual core 2ghz CPU) I always find myself out of "performance" mode (which I need), using only 1ghz per core.While this is easily fixable with "sudo cpufreq-set -g performance", I don't seem to be able to do it before having control of the machine. I would like to be able to boot with my CPU at full power.I would prefer to disable whatever is scaling down my CPUs to having to inject cpufreq-set to change governor. Anyone has any hint?I use default Ubuntu but I boot into a KDE4 desktop. But the same issue happens booting into the Gnome desktop.
For some reason, it seems that 13.37 isn't loading the modules I need for cpu frequency scaling. I've edited /etc/rc.d/rc.modules so that CPUFREQ is set to on. On 13.1, this would mean the powernow-k8 module would be loaded for my AMD cpu, and the subsequent "ondemand" governor would be loaded. However, for some reason this isn't being done during the boot process. I've tried it using both the generic kernel and the huge kernel (I'd been using huge for a long time before without realizing it.) Has anything changed in 13.37 with regards to CPU frequency scaling?
would ask how to fix this warning that comes when i start my centos 5 virtual machine that run under windows 2003 std, previously it run smoothly with linux centos 5.
currently Centos 5 Virtual Machine ____________________ VMware workstation 6 for windows ____________________________ Windows 2003 STD

I want to turn off frequency scaling permanently and totally in the lowest-level way possible. Is there a kernel command line that can be used or is recompiling the kernel without the governor stuff the only way?
Solved. Just modprobe -r and blacklist the acpi_cpufreq kernel module.
Is there any possible way to keep my CPU frequency scaling on PERFORMANCE mode through a reboot? Ubuntu likes to default it back to ONDEMAND all the time.
Trying to set my cpu to Powersave using the CPU Frequency Scaling applet. When I set it to powersave, it goes back to ondemand on its own. On the earlier versions of Ubuntu, I used to be able to set it from the main menu: system>powermanagement, but with 10.10, I don't get that option. Is there any way that I can set it to powersave permanently? I was also able to set it with Ubuntu Tweak, but it does not have that option either.
I just bought asusn a50ij and of course I installed ubuntu, now I have few problems: when I try to add CPU frequency scaling monitor to panel it says: CPU frequency scaling unsupported Next problem:my cpu temp is 49 without any reason.and I cant see my graphic card temp,when I go to Harware Drivers I doesnt show any drivers at all,so I dunno whether its nvidia or raedon it doesnt say anything! Also I installed jupiter and each time I turn on my computer it goes to Maximum Performance how can I turn it off?
The CPU frequency scaling monitor won't stay at 800mhz after reboot or a certain period of time. My goal is to always have my dual core CPU locked at 800mhz to have it run cooler. I'm running Ubuntu 10.10 on my toshiba u300 laptop.
I have a suspicion that this is easily fixed, however a good google (and this forum) hammering having turned up the fix. So I probably have the wrong search criteria, My Gnome Applet for switching CPU Frequency Scaling has 'disappeared' and is not listed in the the Add to Panel.. list of applets.
I have a 2.9ghz AMD Athlon II X4, which I have overclocked to 3.65ghz. I know that Ubuntu automatically changes the frequency of the processor to save power, which I like, but it does not show my overclocked frequency. The highest that the frequency scaling will go is the stock clock, at 2.9ghz. Is my processor actually reaching my overclocked speed?
In order to save power and to cool down my Debian system a little bit, I installed cpufregs the other day and changed it the cpu gonever to on_demand.
Well I came back to the box today and powertop tells me that the cpu has been running at 2.66ghz (max freq) for 99/99% of the time.
Running cpufreq says this: Code: analyzing CPU 0: driver: p4-clockmod CPUs which need to switch frequency at the same time: 1 hardware limits: 333 MHz - 2.67 GHz
When I try to rename a file in a mounted NTFS file system by only changing the letter case, I receive an error message saying that it is not possible because the file already exists. This must be because ntfs is not case sensitive as regards determining a file name. However, it can use and remember whatever case you want to use. So I can change the letter case in the file's name in two steps: saving the file with a different name first and then renaming it again with the original name and the letter cases I want to use.
In Lucid I cannot get CPU scaling to work anymore, in previous Ubuntu releases this was not a problem with the same hardware (AMD Phenom 9500 Quad). I used to load module 'powernow-k8' and 'powernowd' to make it work, but it seems 'powernow-k8' is not available in Lucid. Anyone who has cpu scaling working in Lucid?
OS: Ubuntu 10.04 LTSEmulator: Wine 1.2Program: Propellerhead's Reason 5.0After some toil, I successfully installed Reason on linux. Hurrah.However, the default audio drive failed, and now it doesn't have an audio card selected. .. but this isn't my problem.I would love to go into Options to try and tinker with the settings, but I can't click on it. In fact, I can't click on anything in the window's toolbar (ie File, Edit, Options, Help, etc)The rest seems to work just fine.
so I've got a openSuse 11.3 machine with KDE. As graphic card I've got a 9500GT and as display a syncmaster 570b. Now both work fine with other products (9500GT works fine on my other display and my Windows laptop works fine with the syncmaster 570). I beleive it's because of the frequency. here's a list of frequencies supported by the 570: Technische Daten zu Samsung Syncmaster 570B - TFT Monitor bei dooyoo.de
I also installed nvidia drivers via yast2. But how do I change the frequency? I've been trying to solve the problem for hours. Oh yeah when I connect my 570b to my 9500gt, I sometimes get a picture and sometimes don't. However when I get a picture colors are very strange and it flickers hardly.
I have a server with 4 NICs in it. for HA and speed I have bonded 3 of them together (eth0-eth2) in my wonderful unmanaged 10/100 switch. 192.168.1.3. eth3 is cross connected via the patch panel to another system so that file transfers can be a 1000/FULL. I have created a 172.1.1.0 network between the 2 hosts. Problem is that once i connect the cross over NIC thes rest of the network cant see the server. I am sure it is a routing problem and added ip route add 172.1.1.0/24 dev eth3 172.1.1.0/24 dev eth3 proto kernel scope link src 172.1.1.0 192.168.1.2/24 dev bond0 proto kernel scope link src 192.168.1.2 169.254.0.0/16 dev eth3 scope link metric 1005 169.254.0.0/16 dev bond0 scope link metric 1006 default via 192.168.1.2 dev bond0
I've got a request from one of my company's subsidiaries to block all incoming and outgoing mail for a group of users. I've read up some guides on access.db and I know how to do that, but now they want to allow these users to receive emails from a few select domains, and block the rest. To summarize:
1) Block all incoming and outgoing email to users in team A, except mail from [URL] 2) All other users can receive and send mail from/to any domain.
I have no idea why, but my website times out as soon as you try to use the cart.(which invokes SSL)It seems to have happened after I went live from testing, but I checked my configurations, and I can't see anything awry in my apache2 confs.Has anyone run into this before?I don't know how or why this happened or how to even begin fxing it
