Setting CPU Frequency

I have an Intel Core 2 Duo E6400 CPU (2.13Ghz, 1066mhz FSB) in a MSI P965 Neo motherboard but in the BIOS the CPU frequency is only showing 533mhz. Is this normal and actually is running higher or do I need to change a setting to boost it to the supported 1066mhz?
*Update: I updated to the latest BIOS (v1.4 from v1.3) and it no longer displays the FSB.... I'm guessing it was just a reporting error and their fix was to no longer report it >.>

I had the same issue with my E6400 showing 533 MHz in BIOS. I'm not worried and have chaulked it up to:
1) Speedstep while in DOS/BIOS
2) A calculation error in BIOS
CPU-z 1.35 correctly shows it as 2.1 and shows it dynamically go up and down with SpeedStep.
Finally, my CPU mark and 3DMark scores are all within range of similar Conroe system.
So, this is a reporting issue not an actual performance issue.

K7N2GM-V - Please re-setting CPU Frequencies in the CMOS Setup (sic)

Rebooting after a system hang I sporadically get the following messages:
CMOS Checksum error - Defaults Loaded
Warning! the CPU had changed.
Please re-setting CPU Frequencies in the CMOS Setup
Could someone please translate this for me? I haven't touched the CPU, the CMOS jumper and the battery is good, per the hardware detection menu.
And my CMOS settings are lost, so I have to go back and set the clock, disable the floppy I don't have, boot order, etc.

The battery contacts are clean; in or out of the case the mobo boots fine as long as I don't pull the plug.
But for the answer to my original question, what does this mean:
Please re-setting CPU Frequencies in the CMOS SetupThe Quick User's Guide is not useful here. It says:
Adjust CPU FSB Frequence
This setting allows you to select the CPU Front Size Bus clock frequency. Settings [100MHz]~[300MHz] at 1MHz increment.
In fact with High Performance Mode set to Optimized the choices are only 100, 133, 166, 200, and the answer given is correct:
Quote from: osnavi on 28-July-05, 22:27:47
"...Do you mean the BIOS setting "Adjust CPU FSB FRequency?"
The choices there are 100, 133, 166, 200... " If CPU is 333 FSB you should select 166.
In other words, in the BIOS set up screen, go to Cell Menu and then Adjust CPU FSB Frequency and set it to ½ the advertised frequency of your Athlon CPU.

How to Define Specific CPU Frequency in Laptop Mode Tools?

I would like to know how to set a specific maximum and minimum frequency for Laptop Mode Tools. Here is my /etc/laptop-mode/conf.d/cpufreq.conf:

No, I just want to save battery power. I don't want the CPU to be clocked as high when I'm on battery. I would set the CPUFreq governor to ondemand, but when I issue sudo cpupower frequency-set -g ondemand, I get:
Setting cpu: 0
Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
for example because of hardware which cannot be set to a specific frequency
or because the userspace governor isn't loaded?
The output of ls /lib/modules/$(uname -r)/kernel/drivers/cpufreq/ is:
acpi-cpufreq.ko.gz cpufreq_stats.ko.gz powernow-k8.ko.gz
amd_freq_sensitivity.ko.gz cpufreq_userspace.ko.gz speedstep-lib.ko.gz
cpufreq_conservative.ko.gz p4-clockmod.ko.gz
cpufreq_powersave.ko.gz pcc-cpufreq.ko.gz
Doing modprobe cpufreq_ondemand and trying again does nothing.
So, since I can't use the ondemand governor and then raise the threshold, I need to limit the CPU frequency.
Thanks.

Cpu frequency scaling not working and hdd powers down

Hi,
I recently made a fresh reinstall on my laptop keeping only my user settings (home directory) but no system-wide settings (/etc).
Now I have the following issues:
1) CPU frequency scaling does not work. KDE's PowerDevil tells me, my CPU does not have scaling capability and when I try to start cpufreq, I get this error message:
# /etc/rc.d/cpufreq start
:: Setting cpufreq governing rules , cpu 0 1Error setting new values. Common errors: [BUSY] - Do you have proper administration rights? (super-user?)ble_governors: No such file or directory
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
for example because of hardware which cannot be set to a specific frequency
or because the userspace governor isn't loaded?
The governor modules are loaded:
# lsmod | grep cpufreq
cpufreq_userspace 2096 0
cpufreq_powersave 942 0
cpufreq_ondemand 7990 0
freq_table 2339 1 cpufreq_ondemand
cpufreq_conservative 9172 0
This used to work out-of-the box with the previous install so I'm a bit puzzled.
2) My hard drive powers down after a few seconds of inactivity, just to power up a few seconds later when it's accessed again. The hard drive never powered down on my previous installation. I do not have any power management daemons running and this behavior starts right after booting the machine, before I log in.
I would like to disable this "feature" since I think it's rather bad for the hard drive's health as well as battery life.
Any ideas?:)
EDIT: Cpu frequency scaling is fixed now, forgot to load the acpi_cpufreq module.:rolleyes: There's still the issue with the hard drive, though.

The HDD thing is caused by upowerd, dunno why though.
You can try: hdparm -B 254 <disk device>, but that wont solve the problem permanently, only till you plug and unplug again the AC supply.
you can also try killing upowerd and things will (at least that was the case for me) be alright.
Maybe this is upowerd bug?

Why the CPU Frequency will just stated at 1189MHz when the X230 had AC Power ONLY (Battery Removed)?

Dear All,
I bought a X230 (i7) notebook. I found that if removed the battery from the notebook and only use AC power with the X230 Notenook. The CPU frequency will stated at 1189MHz. It will not change no matter how many program the notebook is running. The CPU frequency will rise to 2.9GHz or upto Turbo when the Notebook with battery or battery and AC power. Why the CPU Frequency will just stated at 1189MHz when the X230 had AC Power ONLY (Battery Removed)? This is not right. Any setting in the X230 Notebook need to change? Please help.
Solved!
Go to Solution.

The situation is probably the same as it was for the X220. A 65W power adapter by itself doesn't provide enough power to run the computer at full speed, but it can when combined with a battery. However the 90W adapter may be able to run the computer at full speed without a battery.
As it was with earler X-series. This is by design. It allows people to travel with the smaller, lighter 65W adapter. However for maximum speed and flexibility it's best to always use the 90W adapter.

Helix CPU frequency limited to 0,3 GHz after replacement of mainboard (Win 8.1)

Hi,
I have a weird problem: The mainboard of my Helix was replaced by Lenovo because it was defective. Now, the CPU frequency does not exceed 0,3 GHz (16% CPU utilization). The laptop is unusable because it is soooo slow. See the screenshot below.
The technician who exchanged it says: "hardware is ok, please "Format C:", it's a software problem " I don't want to do that.
The Lenovo support says: "We don't know."
I tried to run and reinstall Lenovo Solution Center to run a hardware scan, but the service doesn't work.
Who can help? Is this a software or hardware problem?

Do battery levels have any influence on this?
Does it change anything if you unplug the charger?
Did you hard reset both the tablet and the base using a pin?
Do you have the latest BIOS?
If so is "Cool Mode" turned off and power settings set to "max performance"?
Do you have the latest Lenovo Power Management (PM) driver installed?
Did you try switching around between power plans (in Windows - RMB on the battery icon)?

How to make GNOME power management auto scale cpu frequency?

Hello everyone, I installed Archlinux on my new Toshiba U400/H00, everything works nicely, however, I need to manually scale cpu frequency when on AC/Battery, is there a way to make Gnome automatically scale it?
Thanks a lot!

Maybe just go down to acpid level and do it independently of DE devs idiosyncrasies?
For me, the following code in /etc/acpi/handler.sh does the job:
ac_adapter)
case "$2" in
ACAD)
case "$4" in
00000000)
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
00000001)
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 499 > /proc/sys/vm/dirty_writeback_centisecs
esac
*) logger "ACPI action undefined: $2" ;;
esac
I believe the original code there tried to set fixed clockspeeds for these situations, but I find changing governor much more flexible.
Edit: there were some ACPI-related bugs during 2.6.26-27 development cycle, it may happen that you won't get any ACPI events playing with power source. 2.6.28 cured all ACPI problems for me, but YMMV.

X38 Platinum & q9550 - incorrect adjusted cpu frequency?

I have a core2quad Q9550 in my new X38 Platinum. My BIOS is up-to-date. My RAM is Gskill 1333MHz DDR3.
In the Cell Menu in BIOS, at the top it shows
Current CPU Frequency: 2.83GHz (333x8.5) <-- correct speed for this CPU
Current DRAM Frequency: 1333MHz
However the Adjusted CPU Frequency says [2667]!
D.O.T. Control [Disabled]
Intel IEST [Enabled]
Adjusted CPU FSB Frequency [333]
Anyone got any idea what's going on? Is my CPU running at full speed or not?
Thank you.

This was a pre-windows query. However, in order to follow AaronYuri's suggestion, I am now installing Vista 64. I will set everything to, well, as close as I can get to no power management

Problems with CPU frequency scaling

Hello!
I'm having problems following this wiki page in order to set up frequency scaling. My CPU is an AMD Athlon 64 X2 5000+, so I tried to load the powernow-k8 module. However, the device couldn't be found. Turning AMD Cool'n'Quiet fixed that, but soon after loading the module, my computer would crash. Changing CPU frequency profiles in BIOS only changed if my computer would crash immediately or a few seconds after loading the module. My motherboard is Asus M2N SLI.
Could someone help me fix this?

Thanks for your reply!
Unfortunately, I can't seem to even do that. I just ran this after setting the BIOS profile to Auto:
sudo modprobe powernow-k8 && dmesg | grep powernow > dmesg.txt && lsmod | grep powernow > lsmod.txt
As soon as I pressed return, the command seemed to have executed successfully, basically this is what happened:
[davor@kompika ~]$ sudo modprobe powernow-k8 && dmesg | grep powernow > dmesg.txt && lsmod | grep powernow > lsmod.txt
[davor@kompika ~]$
And the system froze. Upon pressing the reset key and booting the system normally, a dmesg.txt file was indeed created in my home dir, but was empty. An lsmod.txt file was nowhere to be found.
I have tried the Standard and Manual (with settings set to defaults) profiles, and they resulted in immediate reboots. I will try a few more times, because I seem to remember the system being able to run at least a few seconds before finally crashing/freezing.
EDIT:
Did it! Since the command did, in fact, execute entirely, I figured the problem must've been the lack of a clean unmount. So I created a small ext4 partition and ran as root:
mkdir /root/logs
mount /dev/sda1 /root/logs
modprobe powernow-k8 && dmesg | grep powernow > /root/logs/dmesg.txt && lsmod | grep powernow > /root/logs/lsmod.txt && umount /dev/sda1
I realize this is bad practice, but I figured running commands directly as root instead of running them through sudo would maybe save a few milliseconds.
Regardless, it worked! Here is dmesg.txt:
[ 327.826619] powernow-k8: Found 1 AMD Athlon(tm) 64 X2 Dual Core Processor 5000+ (2 cpu cores) (version 2.20.00)

P6NGM-L and CPU frequency confusion

Hello all,
Me again. with more questions about my P6NGM-L, BIOS V3.6. These are different questions than in my other topic, so I thought it best to start a new topic.
Anyway, I've just had my E6300 upgraded to an E8500 and it's working fine. However, while both CPU-z and my mobo's BIOS show that it's an E8500 @ 3166Mhz, they also show that the 'current cpu frequency' is hovering around 2000Mhz. I would understand this if I'd had the EIST enabled, but I hadn't at the time (I have now enabled it).
So can anyone tell me what's going on?
Also, while I was looking in the downloaded manual for the mobo to see if it had any info on this, I noticed that it says (somewhere, though I can't find it now. ) 'this board supports overclocking' although of course they don't make any guarantees (Why should they?). I was hoping to overclock my 3.166GHz cpu to 3.33 GHz, but I can't change the Bus speed or the Multiplier. Currently '333MHz and x6' in CPUID and in the BIOS the multiplier is 'x7'.
So is it possible to change any of these things so that I can run the CPU as if it's an E8600, or slightly better?
Any help anyone could give would be much appreciated.

Thanks for the replies Nichrome and XFM.
Nichrome,
I hadn't touched the BIOS for anything to do with the CPU until I enabled the Enhanced Speedstep setting, and before then the BIOS was showing the cpu as 3.16Ghz but showing the frequency as 2000Mhz, after enabling EIST, the BIOS shows both a CPU of 3.16Ghz and a frequency of 3.16Ghz!?
I can't find any way of overclocking the CPU, unless I have to mess about with the memory timings first?
XFM,
I've looked at the link you were good enough to post. I've done the 'My Computer - Properties' thing and it does show two separate speeds. I'm just wondering why my BIOS now (the last time I looked, anyway) didn't show two separate speeds.
I'm sure either this pc or my next one will send me mental.

Does the iphone cpu frequency change when the cpu load is different?

Does the iphone cpu frequency change when the cpu load is different, or it does not change, stay a fixed frequency? if it changes, how can i get the realtime cpu frequency?if anyone knows,please tell me, thank you so much!!!

As a general, historical statement Tonefox is correct. For certain particular cpus woodmeister is correct. Cpus have historically been single frequency units, though over-clocking has been done for several years. Doing so pushes the cpu beyond its guaranteed speed, but has tended to work since most cpus from quality vendors will actually operate at higher speeds. The manufacturer just does not guarantee the results...remember the Pentium fiasco in the early years of that chip? Today manufacturers are ceertifying particular product lines for over-clocking on a periodic basis. And that is what dynamic clocking really is, over-clocking but not at a constant clock speed as has been done in the past.
Much of the silicon on the market will function at higher clock rates, the only question is does the maker guarantee the accuracy and performance at those clock rates.

SCPI command to set the frequency for power measurement on Agilent 53147A?

Hello,
I am trying to automate some measurements which require me to use an Agilent 53147A Freq Counter/Power Meter/Digital Voltmeter. The instrument has an option of setting the frequency of the signal we intend to measure. This is done by clicking the "FREQ" button on the instrument and entering the frequency value of the signal whose power we intend to measure. This way the power meter uses the appropriate calibration factor for that frequency for providing accurate signal power level.
I have been trying to set the frequency of the signal whose power I intend to measure through remote control but have not met success as I have not been able to find the SCPI command associated with this task in the operating manual. Does anyone know what SCPI command is to be used for this purpose? Any comment in this regard is highly appreciated.
Thank You,
Vivek

Hi vivek.madhavan.13,
Try using the drivers for this device found here:
http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=834204A36619504AE04400144FB7D2...
Then, by going to the lowest level that the VIs permit, you may be able to find the SCPI commands your application needs.

Setting GC frequency in NetWeaver 2004S application server

Hi All,
I am looking to set GC frequence in my NW 2004S J2EE engine. I saw various notes and links on JVM settings but nowhere did I find any reference to tuning the GC frequencey. Could you anyone suggest or help with this?
Any help will be greatly appreciated.

Neelesh

SAP recommends the HeapSize to 2 GB per server node, because of the way the Garbage Collection works. Every once in a while, when the tenured area of the memory is exhausted a full garbage collection is triggered. During full garbage collection all processes are frozen and only the garbage collection threads are running. Increasing the heap size increases the time needed to finish the full garbage collection and even though this process will be rarer with more heap, when it happen your server wont process requests for some time. Therefore instead of increasing the heap size SAP recommend adding additional server nodes, which will utilize the memory that you have, but will also cover each other if one node is not available to process requests.
Hope this helps your understanding of the GC frequency.
