Fedora X86/64bit :: Powernow-k8 And Incorrect Pstate 0 Frequency
May 1, 2011
If I boot my system with default BIOS settings (no overclocking), the CPU runs at 3.3GHz and powernow-k8 enables a maximum speed of 3.3GHz, as can be seen from the following:
[Code]....
Clearly, for some reason, powernow-k8 is mis-calculating the pstate 0 or maximum speed and this is reflected in the files within /sys/devices/system/cpu/cpu?/cpufreq/ I have tried to update /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq, however despite the file being writeable by root, the change is not maintained. Other than setting the CPU policy to "Performance" rather than "On Demand", is there any way I can force the correct pstate 0 (maximum) CPU speed?

Im trying to overclock my system and I cannot find a conclusive answer to this issue.It appears that I need to compile a custom kernel, is there a way around this?So where do I go from here without compiling a custom kernel and removing powernow-k8 from it?Is there a workaround to this? There is no setting in my bios either. ECS NFROCE3-A system board.

I have defoptions=quiet in my menu.list file and it keeps printing
ignoring bad line 1 'powernow-k8' across the screen during boot. The thing is that I have removed that line from /etc/modprobe.d/options, so why do I keep getting the warning?

I am testing version 11.2 (Released version) and have this problem (part of dmesg):
[Code]...
So Opensuse cannot lower the speed of the CPU-cores. I tried updating the BIOS without luck. powernow-K8 under Opensuse version 11.1 (dual-boot) works perfect.

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?

I have the simple fortran codes as:
Code:
integer :: i1=2455121, i2=2455121
real :: s1=0.19123840, s2=0.20749992
real*8 :: a1, a2
a1=i1+s1; a2=i2+s2
[Code]....
When s1 and s2 are stated with 'real*8', the 64bit and 32bit systems get the same results.

I just update the system, and the cpu frequency applet stop working. I can no longer lock the cpu frequency. Once I click the cpu applet icon, The whole applet just freeze right there. Does not matter if what I do with it. Well, at least I hope some one just offer me a bit help on how to lock the cpu frequency in terminal. Other wise I can not run Folding@home due to cooling issue.
Post added at 05:08 AM CST Previous post was Yesterday at 11:58 PM CST Well, it seems like the program take of authentication is mess up. I have the same problem when I tried to config my firewall. In the Firewall case, once I type in my password, the whole window just went blank. For the cpu applet case, nothing happen, the window ask for password does not show up. nothing. The system log did not have any entry...neither does the crash log. Which there are lot of entry there since I install F12

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:
cat /proc/cpuinfo
processor: 0
vendor_id: GenuineIntel
[code]....
I notice here that it says between 800 and 800, but does that mean it is currently at 800, or can only be 800.

how to lock the CPU frequency under Fedora 15. I try to run cpufreq comand but the terminal tells me the comand is bad and ask me if I want to install the program. When I click yes. It says the program has already been installed. While I try to use software manager under GUI, same thing happend. Software manager clearly tells me I have not install that program. But once I choose to install, the system tells me all package has been install?

Can anyone get the website below to work correctly with Firefox 3.5 and F11 64bit?[URL]...All I see is the background scrolling slowly and jerkily, none of the buttons at the bottom work. Reboot into Windows 7 and IE8: the same site is fast, smooth, the buttons work and the product details appear correctly in the centre of the screen.
I've tried disabling all adblock /pop up block options, ensured all javascript options are enabled and no change. Could this be a problem with the 64 bit flash player (installed from leigh's sticky thread) or a problem with OpenJDK?

My Notebook CPU has variable speeds from 600MHz to 1.6GHz but since I upgraded to F13 it has not budged from 600MHz.I have already installed the gnome CPU speed widget and even if I set it to "performance" or "1.6GHz" it stays resolutely on 600MHz
The only indication that I can see that there is something odd is the output of acpitool tells me the min/max cpu speeds are 600MHz/600MHz. I don't know enough about the guts of Linux to know if acpitool is defective or if it's just repeating what it was told by something lower down.I will post some hopefully useful listings of some commands run under Fedora 13 and then the same commands on the same box with an F12 live USB.
Code:
Fedora 13
$ acpitool -c
CPU type : Intel(R) Pentium(R) M processor 1.60GHz

Edit: now working, thanks very much Leigh and Dangermouse.
Anyone successfully installed AIR and iPlayer on F11?
I've switched to 32 bit Adobe flash, tried Autoten for AIR and Dangermouse's advice for iPlayer: url.html but it's not working, and trying to install AIR from url results in an endless busy downloading graphic .
I assume my problem is a lack of required packages, though I searched the repositories using YUM extender for the packages listed here: url.html and can't see them either as installed or available.

My desk-pc has an acer AL17AL17. I've tried to install fedora 12 (windows XP works perfectly) and -just starting- it gave me the message: "frequency not supported". I suppose I have to change it, but I don't know what I should do. The installation began, I selected to do a new installation and then, suddenly, the message.
Should I change it in windows? Which frequency do I have to use?
--> On fedora 12: I'm going to install the "Long Term Supported" 6.0 version, as knudfl told me. Anyway, now it doesn't give me that error.

I have Intel Pentium Dual Core E2180 / 2 GHz processor. i just upgraded my system with 4 memory sticks i.e. 7GB of RAM due to my requirements. Now the issue that i am facing is that my 32bit fedora system does not showing and suppoting more than 3.XX gigs of RAM when i consult "/proc/meminfo", "free -m" and "top". Now i have done two thing, first i have installed a PAE version of kernel. In result of this my system become two slow with the following error at startup. Error: starting udev: wait timeout. will continue in the background <Failed> Secondly, i installed a 64bit version of Fedora 10 but still it showing not more than 3GB of memory. Also a kernel bug system alerts me of not supporting more than 3gigs of RAM and ask me to send that bug to[URL]

The Wikipedia says that the frequency of the Athlon 64 X2 3800+ is 2000 MHz.
For that processor, on FC 12 64 bit
cat /proc/cpuinfo
shows:
cpu MHz : 1000.000
for each processor.
Is that supposed to "add up" to 2000 MHz for both? My old GA-K8N-Ultra SLI motherboard has its BIOS set for "top performance", so I hesitate increase any clock speed or multiplier.

I have just upgraded my system to Fedora 14. One thing I noticed after running some applications on it is that it is not possible anymore to figure out on what frequency a wireless interface is using. If I set a wireless interface to monitor mode and perform the iwconfig or iwlist command, in the past, I could see the frequency used on the interface, but now, this information is not present anymore. My wireless interfaces are in monitor mode.
Has the frequency information been removed from iwconfig or iwlist commands? If it has, is there another way to report this information?
Here is an output from iwconfig on my system:

i have an hp pavilion dv7 and am using f13 64bit. my laptop has a built in woofer underneath that i have never been able to get to work. after the latest kernel update today my laptop now has woofer sound. there must be some new support for my laptops audio card. the problem is that it is a little overbearing. how can i a) disable this feature b) tweak the parameters like crossover frequency or gain? edit: i checked the changelog for 2.6.34 and couldn't find any info on any new audio support features.

See: [URL] The problem: Fedora 13 dosen't report the correct CPU speed of my Overclocked E2180. The correct speed, seen by Windows and openSolaris is 3.1Ghz. However, Fedora 13 (final) still dose not report it correctly.
However, today I downloaded linpack from here: [URL] and Linpack correctly state my CPU speed as 3.1Ghz: Btw, I have the pata_acpi module installed if that helps. I could not edit (even as root) the file at /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed. Even cpuid/cpuinfo and the GNOME CPU Frequency Scaling Monitor 2.30.0 reports the speed as 2Ghz.
