[SOLVED] Question about CPU temperature

Hi everybody,
I just want to ask a question about "standard" CPU temperatures because my laptop (a Dell Vostro 3700) is permanently hot with the fans on even when I am not doing anything special.
I have CPU freq scaling active with the conservative governor, and I use Gnome Shell 3.2 with an nVidia using the nouveau driver.
Here are "stable" temperatures while writing this post:
# sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +72.5°C (crit = +103.0°C)
nouveau-pci-0100
Adapter: PCI adapter
temp1: +78.0°C (high = +100.0°C, crit = +110.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +73.0°C (high = +95.0°C, crit = +105.0°C)
Core 2: +73.0°C (high = +95.0°C, crit = +105.0°C)
And this is the output of mpstat
# mpstat -P ALL

10:16:50 PM 3 1.36 0.20 0.39 0.02 0.00 0.01 0.00 0.00 98.01
The fan, of course, is full speed (very annoying)
I think that these temperatures are quite high, but I don't know what's really causing all this heating because my laptop is basically idle.
Any suggestion?
Thanks.

Question about CPU temperature

Hi, I have just built a new system with the following,
Motherboard - MSI 760GM-P23 (FX)
CPU FX 6300
and as this is my first venture over to the AMD side of PC's I have some questions about the CPU temp.
The image below is from my system under load, I'm told that the temp readings from AMD CPU's are not accurate below 40c?
The FX 6300 'package temp' cant be accurate with a low of 13c it's simply not possible in a room that's almost 20c.
What is TMPIN1? I hope that's not my actual CPU temp as 69c is way to high. and a Google search for TMPIN1 brings up lots of forum posts regarding MSI boards, Hence my post here.
TMPIN0 looks like the most likely sensor for CPU temp but I'm just not sure, so which one is it? and where is TMPIN1 reading it's info from?
Regards and many thanks, Dave

What you see with HWINFO is the readings from two different sources. One is the reported temp by the AMD sensor, the other is the same temp but as reported and translated by the Fintek chip that MSI generally uses on their boards.
The differences in readings boils down to the digital signal to analog conversion by the two data suppliers, .i.e AMD sensor/Fintek chip.
If in doubt, always use the higher reported temp as the acceptable one. Quite frankly, I would think what the Fintek reports is probably close to what the real temps are. Common sense will dictate that what you see from the AMD sensor is virtually impossible unless you use liquid cooling.
Also remember that the software in use may differ in readings slightly.
The Fintek chip is reporting 2 CPU temps. I summise the higher as being the CPU core and the lower value as being a sensor in the vicinity of the CPU that MSI has added.
Comparing the info with your HW Monitor, I further believe that TMPIN1 is the same as the Fintek CPU higher temp. TMPIN2 is the one for the lower CPU value in HWINFO and TMPIN0 is probably your southbridge.
If you wish, run both these software packages at the same time and stress your machine in Prime95, Then you can monitor and figure out which ones are going up or down in unison. You may also find that the temps will be a lot closer then.

Question about CPU usage for video playback

I've asked a related question already on the Safari forum, but would like some clarification, please.
The speed of this iMac is 400 MHZ and whenever I go to YouTube or almost any other site that requires video I see that the CPU usage can peak way up at 80% or more. I have Flash 9 installed which has a minimum of 500 MHZ, so I get pretty choppy video, but that's not the issue here. I can live with that. I keep any other applications closed. I'm often running a small fan over the top of the iMac to help vent the buildup of heat. I can monitor the temperature at the Hard Drive and I suppose that gives me an idea, of sorts, about general temperature conditions inside.
The answer I got was that this kind of CPU usage could be detrimental to the processor as it builds up excessive heat and to keep this kind of video to a minimum.
My question is can anyone roughly suggest what a maximum time on YouTube, for example, would be, 2 minutes, 5 minutes, is 10 minutes too long? I have plenty of RAM at 768. Some guidelines?
Thanks.

Hey WZZZ,
Thanks for the star and kind words.
I'm the de facto Mac guy at my kids' school and we have around 25 iMac Slot Loaders working there. You can imagine they get abused quite a bit. There are 10 running Garage Band in the Music Department. That puts a tremendous strain on the CPU and I'm actually surprised that they run it so well. My son had a 600 iMac running GarageBand, he was complaining that it was getting jumpy and when I looked at it he was running 10 unlocked tracks simultaneously! So now he has an eMac G4 800 and that of course runs a lot better.
So to sum up, with all the abuse of those machines in terms of the CPUs the problems I have with them have nothing to do with that. The problems have more to do with parts of the OS that they toss, headphone jacks abused, CDs jammed in the slots, and the like.
A couple of other related things. I've got Hardware Monitor, demo, installed and I think it reported it could only find the hard drive sensor, if I'm not mistaken - nothing else on this Mac with a sensor. Is that right?
I see references to CPU sensors on 400 iMacs but on the 400 I have here for repair Temperature Monitor reports no sensors. Perhaps there were different versions of the 400.
But very good to hear that the fan is a good idea for CRT related things. Should I keep the fan running-mostly for that hard core CRT stuff- even if the computer is sleeping and the room temp. is only around 62-64 F.? (We need to put on warm clothes to sit in front of this thing now, but worth it to keep this old machine happy).
On the one I did the fan pushed the airflow in the direction of the passive flow of the iMac - in at the bottom and out the grill by the handle.
One more question, more out of curiosity than anything else: If I move this small clip-on fan close to the case - right now it's about 3 feet away and the image is stable - the screen begins to flicker and flutter quite a lot. My theory is that that's happening not necessarily because of electro-magnetic interference from the fan motor, but rather, because the back of the tube is getting cooled unevenly. What do you think?
Well the classic failures that I see in the iMac are in this order:
1) Dielectric breakdown of the flyback transformers internal insulation. This is heat/age related and a common problem with CRTs in general.
2) Breakdown of high voltage electolytic capacitors and regular high voltage capacitors on the neck board and PAV supply.
3) Solder problems with the flyback itself. This is diagnosed by the upside down boot technique.
I used to repair these problems but now it's easier for me to swap the Firewire boards into working 350s. I've got 12 of those in the basement currently.

[SOLVED] Question about resolv.conf

I successfully configured my Arch box with a static IP by following the instructions on the Arch wiki page here but had a couple of questions about configuring /etc/resolv.conf:
1) What is the proper way to obtain the domain name that should be inserted into resolv.conf?
2) What exactly is this domain name used for? I read the man page but still don't really understand it. Why do I need a domain name if I already have a working set of nameservers to resolve IP addresses?
EDIT: @ewaller Yes I edited the OP because I realized that my original problem was that I just hadn't added a domain name in my resolv.conf file. I edited my original post because 1) the instructions are already posted clearly on Arch Wiki so my post really wouldn't be beneficial and 2) so I could ask my real question without making other people waste their time reading through my other nonsense

Yes, I know how to get a nameserver, but I'm asking about the domain name that goes in resolv.conf. The Arch wiki tutorial for setting up static IP uses the following resolv.conf as an example:
nameserver 61.23.173.5
nameserver 61.95.849.8
search example.com
My question has to do with what the "search example.com" does. I don't have a domain name associated with my machine, but if I remove that line, then I get "web page unavailable" when I try to load any web site, which suggests that I'm not connecting to any nameservers right?

[SOLVED] Question about GCC error messages.

I'm currently taking a course in C programming, and I have a question about the error messages returned by GCC.
When ever i try to compile a program containing syntax errors, i get cryptic and not very helpfull error messages.
If i try to compile:
#include <stdio.h>
int main(void)
int i;
i = 0
return 0;
I get following from GCC:
error.c: In function â:
error.c:8:2: error: expected â before â
But shouldn't the message be something like:
error.c: In function 'main':
error.c:8:2: error: expected ; before 'return'
or am I mistaken?

Woah. That is very strange. I've never seen that before.
I assume you're using Arch Linux. What text editor did you use to write the code? Which terminal application are you using?
...those questions are probably unrelated to the problem, but we might as well get them out of the way.

I cant find any threads or sites that define idle temp for this cpu and graphic card,
in normal stance and high performance/ playing games.
I have an extra cooler (link: http://www.mimovrste.com/artikel/2210016012/hladilnik-za-prenosnik-akasa-ak-nbc-02b ) underneath the laptop. It does help much but still its running on *53C* (celsius) while surfing the internet.
Without that cooler its around 60C. It sounds strange to me.
When i play games on high performance the core temp goes to *63C*, without that xtra coller *+80C!!!!!!*
I clean the heat sinks every 1 month with a huge compressor :)
I dont let any dust in there. I have the laptop like a year now runs great, but still Im interested whats the temperature of our similar models.
I had some "turn off problems" when i didnt have the extra cooler, but now it runs great, but still im not convinced its the "normal" temp. :S
So plz help a lost soul surfing the internet finding nothing to answer his question :)
tnx

heya
the problem is i hate vista :) i have installed xp on it. there are no xp drivers for this laptop. i mixed with some similar models same components xp drivers and everything is working well now ;) no yellow thingies in the system window - hardware components. all cool. all games running with no artifact and no weird thingies.
but still im interested in the temperature.
i installed the old Toshiba power saver (win xp) works fine but i dont see any difference with it. no effect. cooling method is on high(as it was on the begging) and no changes. i hoped the vents gonna speed up just a lil bit . but didnt.
how the temp sound to u? high or ok? for an AMD cpu :) the gfx is at 29C :) the cpu runs at 50C surfing internet , while playing games it goes to 63C.

[Solved] Questions about Arch on T420s

Hello everybody,
I'm relatively new to Arch and switched from Ubuntu last year. Since then I've learned a lot about Linux in general due to the great documentation provided by the Arch community.
I've managed to install Arch on my Thinkpad T420s with an UEFI Setup using Archboot. But still there are open questions.
My first question is about the UEFI System partition and grub2. Should the UEFI partition be mounted to the filesystem? What about updating Grub2 (eg for setting boot parameters) when the UEFI System partition is not mounted to the filesystem. Up to now I've set boot parameters by manually mounting the UEFI partition and editing the Grub2's menu.lst equivalent. I think this is not optimal.
My second question is about some graphical artifacts in Gnome 3. The T420s uses Intel HD 3000 Graphics. Sometimes icons in nautilus disapear or get replaced by black planes when hovering over them with the mouse cursor. Similar black planes replacing icons can be observed sometimes in Evolution or Rhythmbox. Furthermore gnome-terminal becomes transparent sometimes when I'm scrolling or switching between powertop2 tabs. Anyone else observed similar issues on their T420s or on other models with an Intel HD 3000? I use several options for the i915 driver but none of them seem to be related to the graphical artifacts. Furthermore I've disabled dVT in the BIOS.
options i915 modeset=1
options i915 i915_enable_rc6=1
options i915 i915_enable_fbc=1
options i915 lvds_downclock=1
options i915 semaphores=1
My last question is about the USB ports on my T420s. I've 3 USB ports, one on the left side (USB2.0) and two (USB3.0 and another USB2.0) on the back side. When I plug in a HD on the left side everything works fine and the filesystem is automatically mounted. When I plug in the same HD on the ports of the back side the HD isn't even recognized. Interestingly when i boot with the HD plugged into the back side ports everything works fine. Can you point me any directions how to solve this problem?
Hopefully sombody using Arch on a T420s has already solved these issues and could share the solutions. Otherwise I would be grateful for any suggestions.
Sincerely yours,
Tobsen

Hi Tobsen, I have a T420 also. Perhaps my experiences will be some help?
Regarding the USB ports: I installed Arch on my T420 with the Kernal 3.0.3 snapshot and all the USB ports worked out of the box. That sounds like a problem with udev to me, though. Have you checked the wiki article on this?
Regarding the graphical artifacts: For me, when a popup window appears from hovering the mouse over an icon, the window is sometimes blank grey. It's totally inconsistent, and I can fix it by just hovering over it again, so I haven't really bothered to examine the source of the problem. Could this be related to your problem with the GPU? I figured it was a problem with the windows manager I'm using (Enlightenment e17), which is unstable.
Regarding UEFI: I don't use GRUB2, so this may not be good advice, but I personally feel like you should avoid auto-mounting partitions you don't always need. It slows down boot, and if the partition is mounted, user error could damage it. I say you should keep doing what you're doing.

Need help ASAP, have a tough question about CPU and BIOS...

Alrighty guys... I'm not super smart when it comes to BIOS and the nitty gritty computer stuff, but I know my way around. Here's the thing...
This is the desktop I have:
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=120&prodSeriesId=...
It's sorta old, but it gets the job done quickly. I had an issue with it some time ago and I thought it was the power supply, so I replaced it. While I was waiting for the power supply to arrive, I took the CPU out, just to be nosey. I accidentally bent a couple of the prongs, so I had to get a new one.
First, I bought a Black Edition AMD quad core, but the 125W was too high for my 95W chip. I had to sell it. I sold that and I just bought a new one:
http://www.cpu-world.com/CPUs/K10/AMD-Phenom%20X4%209850%20-%20HD9850XAJ4BGH%20(HD9850XAGHBOX).html
I put it in the computer, boot it up and it goes to the HP boot screen and then goes to a black screen stating that the CPU is not compatible and that it's going to shut down. When I reset it and try to press F10 or any of the keys it states that it's going to go to that screen, but then just goes to the black CPU shutdown screen again. There is one thing that the computer will do though. When I press F2 when it's in the black shutdown screen, it will SOMETIMES load the two HDD's that I have. It's just really weird. One time I got it to go to a HP diagnosis page. It showed the CPU and had a big green check next to it. It checked the memory too, and it got a check. Then it just froze and I had to shut it down. I can't seem to get it to that screen again.
My real question is why won't it recognize that my CPU is compatible? Do I need to update my BIOS? Can I do that without a CPU and a running OS? I really don't feel like selling this processor. I know that I should have just gotten the exact same processor model that came out of it.
Any info will be nice! Thanks so much!!

Here are the specs for your HP Pavilion a6720y Desktop Computer and it's M2N78-LA (Violet) motherboard. According to the specs, your computer supports the following CPUs;
Socket type: AM2/AM2+
TDP: 95 watts
AMD Athlon X2 (Bt)
AMD Athlon 64 X2 up to 6000+ (W)
AMD Phenom Triple-Core up to 8xxx (AM2+) (Toliman)
AMD Phenom Quad-Core 9xxx series (AM2+) up to 9850 (Agena)
Based on the CPU part number supplied, you purchased another 125 watt CPU. The AMD Phenom X4 9850 (HD9850XAGHBOX) isn't going to work because it is rated at 125 watts and therefore is not compatible with your motherboard. Please consider returning (as Dave suggests) or selling your current CPU and getting one of these 95 watt AMD Phenom X4 CPUs.
Please send KUDOs

Question about cpu support

Hi have been absent for awhile then about two weeks ago I stopped here regarding a prob I was having with my mouse. I read a post aabout somebody who had successfully changed his cpu multiplier using the k7n420 which nobody had reported doing successfully for several months after the boards release. At least that was my impression. After confirming that someone had done it and that after updating their bios to 2.6 the multiplier could not be changed again I decided After six months of running steady at the default settings. I busted out my silver pen and proceeded to unlock my athlon 1700. To my utter astonishment I could now freely set the multiplier. My previous systems were all overclocked and I had a watercooling rig mothballed in the closet. My question is if the k7n420 will support the 2600 does that mean that the bios will include a fsb of 166 or will the multiplier on the new cpu's be higher than 12.5. My current settings with the unlocked cpu and watercooling have me maxxed out at 12.5. I blew up one of the first boards I had by using the fsb as a means of overclocking and do not wish to risk the same "early chipset initialization death". But I have upped it a little and the system is unstable at anything more than one notch above default. However the system is fine with the default settings and I am currently at 12.5 with the voltage at default. increasing the default voltage did not improve the trouble when I increase the fsb. So I was hoping that a bios release would either include the 166 fsb or a higher multiplier if there is one (I dont think there is though). It seems to me that if they are to support the 2600 there will have to be a change because at default and 12.5 XP2000 is the limit.
PS The ring buffer problem appears to be related to a 24x10x40 cdrw from iomagic which I had bought on sale for 49.99 "I couldn't resist getting one for the price." After I noticed the ring buffer error in the event log always followed an atapi controller error and the a cd error I removed the iomagic burner and put my previous LG8120b back in and have not seen the problem since. iomagic was less than helpful and after researching the burner I found pretty much nothing other than others looking for help with the same burner. Their is no information on firmware for it and some of the mostwell known cd info sites hardly even mention it. On top of that the support guy I chatted with didn't know nvidia had a chipset and told me I probobly had a via even after I explained to him that it has been around for awhile I closed by suggesting he go to nvidia's web site and see himself. I mean really they already have another chipset about to hit the shelves how can a tech support person not be aware of these things.

rosmini,
Since you are on Tom's Hardware site, they have a video, which has been referenced in this forum several times, on how to safely unlock the processor.
I would not bother with trying to unlock the processor until they come out with the next series of chips. There is talk of the 2400+ and 2600+ coming unlocked. Then the processor you have with we worth peanuts and then if you want to take a chance on trashing it, go for it.
Your best bet is just raising the FSB a few notches and you will get the desired effect and more. It give you a higher processor speed but most importantly you get the greater memory bandwidth. That is where you really see the benefits. Look at the GeForce Cards as an example. Overclocking the Core does little, but overclocking the RAM makes major boosts in performance.
Take Care,
Richard

Question about CPU upgrade for Satellite A30-104?

Hello,
My Satellite A30-104 has recently come to the end of its warranty, and having had to open up the heatsink for cleaning and seeing that the CPU was accessible, I wonder if there is any (likely) scope for upgrading it.
The processor is a Celeron (Northwood) 2.6GHz. I'm not looking for more grunt, I'd prefer a lower-power chip, though the much larger L2 cache of a Pentium 4 is also desirable. I'd be very grateful if anyone could advise whether any upgrades are likely available, and if so which chips would be appropriate? If I can give any more useful spec information, please ask.
Thanks in advance.

Hi, thanks for the reply -- and sorry it went ignored so long, it turns out I hadn't configured my email watches correctly :(
I appreciate that it's really a job for a technician, and I don't want to brick a perfectly good computer, but I think its EOL is not far off anyway so I'm prepared to be a little more invasive than before.
I know that I can get at the CPU, and I know the basic precautions for physically tampering with PC internals.
What I'm first of all concerned about is this: if I replace the CPU, and it doesn't function with the laptop, can this damage other parts of the system such that it'd no longer work by replacing the original?
The Celeron puts out a great deal of heat (all the time) but isn't it fair to assume that a P4-M will be less hot?

[SOLVED] Question about systemd-user-session

Hi!
I'm trying to setup a systemd --user session (using user-session-units and xorg-launch-helper from aur).
I have a couple of questions; this is my .xinitrc now:
#!/bin/bash
export BROWSER=chromium
if [ -d /etc/X11/xinit/xinitrc.d ]; then
for f in /etc/X11/xinit/xinitrc.d/*; do

tint2 -c .config/tint2/dragonauta.tint2rc &
conky -p 5 -c Script/conky.conf &
exec openbox
1) is "if" statement required when using systemd-user-session? And if yes, how can I reproduce it?
2) "conky -p 5 " will wait 5 seconds doing nothing. Will this mean that other .service will wait for it to finish? (i guess no, since they're executed in parallel).
3) how can I export "chromium" as my default browser?
Thank you very much!

I followed everything in that wiki, and in KaiSforza and sofar github page.
I finally managed to get my old method (autologin to vt and autostart x) to work together with systemd --user: i put in .xinitrc "systemd --user" and deleted everything else.
So, my .config/systemd/user/ works. The problem is in the [email protected], i guess. I configured it like wiki says, mind to post here your /etc/systemd/system/[email protected]?
Thanks.

[SOLVED] Question about Feh

I installed feh to use as a file browser image launcher (https://wiki.archlinux.org/index.php/Fe … e_Launcher) and as a desktop wallpaper manager (https://wiki.archlinux.org/index.php/Fe … er_manager), but it seems that I each time must use "sudo" for this. Therefore I think the script from the wiki page will not launch in Thunar and that the wallpaper will not load on start up in i3. In order to do this, I think I must add my user to a group, but I'm not sure which one or if it is the right way to solve it. Would you please assist me with this and thank you in advance.

Thank you for your advice, I should not use sudo as often as I do.
In Thunar opening an image with the feh_browser.sh script gives the following message.
Failed to execute application "feh_browser.sh".
Failed to execute child process "/home/kohaku/feh_browser" (Permission denied).
For the wallpaper, I followed the wiki page about i3 (https://wiki.archlinux.org/index.php/I3 … _wallpaper). The following command gives the following message.
$ feh --bg-scale /path/to/image.file
feh WARNING: /home/kohaku/.feh/wallpaper/touhou.png - No read access
feh ERROR: Unable to load image /home/kohaku/.feh/
I have added
exec --no-startup-id sh ~/.fehbg
to
~/.i3/config

[SOLVED] Question about bash

The default .bashrc file looks like this. When installing rvm I noticed that it is not sourcing scripts under /etc/profile.d.
# ~/.bashrc
# If not running interactively, don't do anything
[[ $- != *i* ]] && return
alias ls='ls --color=auto'
PS1='[\u@\h \W]\$ '
I just solved my issue by adding the following code to .bashrc. I was just wondering if this should be done by default perhaps in the package that installs /etc/skel/.bashrc?
if [ -f /etc/profile ]; then
. /etc/profile
fi

Seems that it is an rvm issue. After a bit of searching for rvm problems I found this post that gave me the rvm specific solution. This is probably the preferred fix since its just rvm that's the issue here.
http://askubuntu.com/questions/40287/et … ng-sourced
The key is serveral posts down...
Installing RVM as multiuser requires the user to run this command:
echo '[[ -s "/etc/profile.d/rvm.sh" ]] && . "/etc/profile.d/rvm.sh" # Load RVM function' >> ~/.bashrc
So I can remove the /etc/profile bit now. Thanks for stearing me in the right direction to fix this.

[SOLVED] Question about clipping

Hello,
I'm using JOGL and I have question. When the camera gets close to my test-house, JOGL automaticly clips parts of the house. Have a look at [this image|http://img194.imageshack.us/img194/6236/clipping.png] to see what I mean.
My question: How to prevent that clipping? I don't want it to clip...
Thanks,
Matt
EDIT: Solved it myself, I had to lower the perspective lower-limit (gluPerspective)

See my first post.

*Solved* Question about ATI Drivers

Ok, I'm just finished installing, and I know most distro's, ask you to remove the open source drivers, before adding in FGLRX drivers. Looking at the wiki, I didn't noticed if this needed to be done, and after going through the install, I rebooted. It went as planned until kdm went to load. The screen was unreadable. I used the cd media to mount root, and removed catalyst, and re-installed the opensource drivers. All is well atm, so I'm trying to figure out what I missed. My question atm though is during the FGLRX install, it ask's if you want to removed the opensource drivers due to conflict. If I hit yes, will pacman it automatically remove the required drivers, or do I need to manually remove the Fx86 drivers on my own?
I do apologize for not having a /etc/X11/xorg.conf report, as it slipped my mind while fixing everything. I'll try to make a better habbit of getting it made. I did do a aticonig --inital before the reboot, so i know it won't that.
If I missed anything on the wiki, please let me know, I'll look again at it after dinner.
Thank you all for your time in the matter.

Hi there
First off, which installation method are you following? (ABS using the AUR package, the unofficial repository or the AMD installer). Depending on which method you use, you'll have (or not) a resolved dependency. For instance, you have to remove both the open source driver and your former xorg.conf file (safer is to back it up) to be able to install Catalyst with the AMD's site installer.
If you use AUR (with a tool like Yaourt for example) or the repo method, pacman/yaourt should do it for you, but in a lot of cases it doesn't (I switched to Catalyst having my OpenBox session built already, so when I tried to remove the open source driver it complained about all of the apps that I had installed for removing a dependency like libgl or mesa) and you'll have to do a pacman -Rdd xf86-video-ati to make it work
I'm wondering if you remembered to add the mkinitcpio hook (which is needed to make Catalyst work).
What I would suggest is to re-read the wiki page for Catalyst, see if your card is still supported by Catalyst, maybe your card needs Catalyst-Legacy...
Best of Luck with that
I figured it out, and got it working. I had a typo adding the module for flgxr driver. Fixed it and a soft boot later, all is well. I also deicided to make it so I have to "startx" into my gui, incase this happens again, I won't need the installation media. Thanks for the input.
