I have a notebook with AMD Athlon 64 QL-62 2 cores CPU. Normally the temperature is 50-52 Celsius in idle but with Ubuntu 10.04 beta 2 idle temp is 60 Celsius. /proc/cpuinfo shows both cores on 1GHz which is good but still temp is higher than usual. I tried to find solution using Google but I didn't find anything.

I am using the standalone k10temp temperature sensor but it doesn't give the actual temperature of the cpu, just some "bogus" temp value that isn't very useful.Does anyone know how you can calculate the real temperature from this reading?

View 2 Replies View RelatedI have installed the ubuntu 10.04 beta 2. I have notice that it has high temperature. I have try the "top" in terminal. There are no high usage of CPU and Memory. but still get high temperature. same in karmic 9.1. I have been using this ubuntu 10.04 beta2 fresh install just today. I did not do anything or install anything. It gets hot easily after few minutes. It was installed properly and no problem.
2nd problem is I try to reboot then i see the wifi signal and it detects my wifi and also my accesspoint. so I try to connect. I was connected to my accesspoint. My accesspoint is near my side. then I click firefox to test the connection. but no luck. cannot display page. maybe the internet was block even i was connected to my accesspoint. I try to check the signal then I saw (88%).
Well, today I've installed 11.04 on my laptop. Fresh install.I'm getting the following temps (idle)
Code:
Adapter: Virtual device
temp1: +64.0�C (crit = +126.0�C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +81.0�C (high = +100.0�C, crit = +100.0�C)

Ever since I installed ubuntu 10.10, my laptop is shutting down due to high temperature within 15-20 mins. It makes my laptop literally unusable. Had posted the issue, got some advise but the issue didn't get resolved, hence posting again.
Below is previous post.

Is there any tool or way by which I can check if it's a hardware issue.
cpu temp in Suse 11.2 is over than 55 C (sysem don not have any task) , but in windows 7 temp is 42 C
in fedora is 46 C I have new fresh install of suse 11.2 my cpu is : AMD Phenom(tm) II X2 550 Processor
what my system working warm ?
On my linux distro (arch 64bit, kernel .38) temperatures are stuck @ 60 �C in idle!Temperatures were measured by lm_sensors.Ubuntu confirms the issue.My archlinux setup is new; I added these modules after installing cpufrequtils: powernow-k8 for cpu scaling ondemand governor enabled and it is the default governor.cpu scaling is working.No proprietary video driver installed. Using xf86-video-ati/radeon
My suppositions:
a) undervolting not supported/bug/what everelse?
b) proprietary drivers needed?? maybe the high thermal power is produced by GPU and not from CPU?
My Samsung R530 laptop is over heating, I believe it is the fan because I can't feel it working at all. When it over heats it just shutsdown. A few times it is came up with a warning while shutting down for a split second saying a extremely high temperature and shutting down seconds later. I am running Ubuntu 10.10 with Nvidia Geforce with Cuda. I have tried reinstalling Ubuntu, installing Fedora... Nothing I have tried has worked.

View 9 Replies View RelatedI am attempting to Run Ubuntu 10.10 on a system with 128 CPU cores (64 dual core processors), but Ubuntu is only detecting 32 cores. I've looked and looked and cannot find any information on this topic; is there a core limitation in the kernel configuration that I missed? Currently I am using Ubuntu 10.10 Desktop, would I have more luck with 10.10 Server or another version?

This is a Linux Box.
Here is the output and I need to know how many CPUs we have and how many cores per CPU.
I'm using Ubuntu 10.04 x64, and I have an AMD Phenom 2 x4 940 CPU. First I have to underline that four cores worked perfectly in previous versions of Ubuntu as well as Windows.
When looking at system monitor it tells me that I have two CPUs/Cores, it should be four.
This is the output of CPU info:

processor: 0
vendor_id: AuthenticAMD
cpu family: 16
model: 4

I have a HP laptop with an AMD Athlon X2 Dual Core QL-65 and an ATI Radeon card running Ubuntu 10.10 When I run a video file using Movie Player (or VLC) through the HDMI output to my TV the 'System Monitor' indicates that both processors are running at around 100% with the fan running continuously.

I am running 64bit 10.10. For the last fortnight system has become very sluggish responding to input. Programs greyout and become completely unresponsive for long periods of time and cpu usage on one or both cores ramps up. As I type it is c.80% on both. System Monitor shows usage on the cores mirroring one another. top in terminal shows Xorg at 99%. I have attached a screenshot. I have rolled back and/or reloaded the Nvidia graphics drivers to no effect.

I have Dell Latitude D420, with Core Duo U2500 @ 1.20Ghz, using Debian testing (Wheezy) 32bit, GNOME. Please help! There is no purpose to use a system which drains max. half capacity of a machine. hOPE, that is not a case . How do I know if both cores are working?
View 6 Replies View RelatedWhen I was using Virtual Box in Windows 7, I could choose how many CPU cores to assign to the guest OS. Now I'm using Linux, and when I installed Virtual Box, I couldn't find that option. System Monitor shows that when the VM is busy only one CPU core goes to 100% while the rest are near 0%. How can I make Virtual Box in Linux use multiple CPU cores?

I am running RHEL 5.5 on a Sun 4450 with 24 cores. We use Sybase database. Licensing for Sybase is by core. I would like to restrict Sybase to using 8 of the 24 cores and allow other apps on the system to use the rest of the cores. I want to reserve 8 cores for Sybase use only and Sybase only has access to those 8 cores.
Many commands in Mathematica 8 (Integrate, Simplify, etc.) seem to only be using a single core on my system. Is there any way I can change the affinity so that it utilizes all cores for computations?

View 1 Replies View RelatedSo I recently built a gaming computer, which I typically use windows for. I'm mainly a linux user and I have separate computers for that. But, I wanted to try an experiment with linux on my gaming computer due to it having the best hardware I have.Anyways, I have an AMD athlon II x3, with the 4th core unlocked. Windows will boot up and use it just fine - it considers it a phenom II x4 b40. However, linux will not boot up as long as that 4th core is unlocked. grub is responsive but once it begins booting, it doesn't really do anything. its not just debian, its any linux distro.
i've never heard of linux having problems with core unlocking, and i have a pretty good motherboard (one of the top 5 socket am3 boards). i'm also very surprised to see windows somehow manages to accept this but linux doesn't.
I am testing version 11.2 (Released version) and have this problem (part of dmesg):

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.
identifying the number of cores each processor is running.
I have checked /proc/cpuinfo but i dont find any core details inside it and I can find only no of processor and its speed.
Newbie question here. I just realized that I can tell make to use multiple cores to compile by doing PHP Code:makewhich is just awesome on a quad core with hyperthreading (I just compiled 2.6.33-rc5 in under 5 minutes!) I know aliases are possible, though I've never had much need. What I would like to know now, is if it would be safe to alias make to mean PHP Code:so that by default I use 6 of the procesors when building or if there would be occasions that compiling on multiple processors would be a bad thing
View 10 Replies View RelatedWhenever I monitor my CPU's, it seems only the first is ever utilized, with the second always being at 0%.Does this mean it is not being used, or just not being reported as in use?Is there anything I could do to improve the situation if it is not being used as much as it could be?On Windows, I can assign processes to both cores, or either one. Is there a way to do something similar in Linux?
