  • CPU installation

    - by David Oneill
    I'm in the midst of building a computer (this is my first time). When I first put the heatsink on the CPU, I was a little off center. Some of the thermal compound came off, so when I re-centered it, it isn't completely evenly distributed. So here's my question: how picky are CPUs in terms of how evenly the thermal compound is? Should I take it apart, clean it, and apply a new layer of compound? Or can I just keep an eye on the CPU temperature? (I'm not overclocking or anything, if that matters)

  • Problems with chip fan and CPU fan

    - by JS Bangs
    I have a five-year-old ASUS motherboard that has been working fine for me for years, until I attempted to power it on yesterday and got a CPU fan speed and chip fan speed warning. Cracking open the case and powering the computer on, I can see the chip fan working, but it appears to be hitting something as it makes a very loud buzzing noise. The CPU fan, meanwhile, starts up when I power on, but slows down and stops after a few seconds! How can I address these problems? Is there any way to fix these sort of fan speed issues without just replacing the fan (which in the case of the chip fan, probably means replacing the whole motherboard)?

  • Limiting Sybase ASE 15 CPU usage on VM

    - by reiniero
    I've set up a single CPU Sybase ASE 15.7 test/hobby/experimentation system on a Debian Squeeze x64 KVM VM. I notice the CPU load goes to 100% and stays there. Definitely not a Sybase guru, only interested to see if some programs I'm running work on the database. Looking at Sybase docs it seems ASE detects the machine is idle and then takes over all processing just waiting for a connection (and if needed, doing some housekeeping apparently). Normally that would be fine but as it is running in a VM it's taking away processor resources other VMs could use - and the increased fan noise of the PC near my desk annoy me. I've tried to remedy this: set the "runnable process search count" parameter from DEFAULT (2000 IRC) to 3 in /opt/sybase/ASE-15_0/SYBASE.cfg from http://sybase.reygrobellet.com/tutorials/install_sybase_vb/standalone04_configure_oralin11#TOC-Configure-kernel I added this to my /etc/init.d/sybase startup script: echo 0 /proc/sys/kernel/randomize_va_space (though I don't think it'll make much difference) How can I tell Sybase to "behave" and not hog the processor - I don't mind reduced performance.

  • Why is my CPU fan so loud?

    - by tiiquu
    I bought an old PC to use as a second PC. Everything is fine, except for one thing. The CPU fan is terribly loud! I did a lot with PCs but I never did much with CPU fans. If I want to replace it, what do I have to look for? The fan is 8cm long on each side and 11cm diameter. It is just clipped to the cooler. The PC is a P4 3 GHz. I don't want to spend much money, as I only paid 50 euro for the whole PC. I would prefer to buy a fan for 1-3 dollar or something at eBay but I am not quite sure which one I should buy (which fits). Can you advise?

  • Diagnosing high CPU waiting

    - by Will
    I have a monitoring server that is running icinga/collectd/graphite with about 50 hosts. I have noticed high load/slugging performance on the box. If you take a look at top, you'll see: Cpu(s): 0.6%us, 0.2%sy, 0.0%ni, 7.6%id, 23.4%wa, 0.0%hi, 0.2%si, 0.0%st Notice the HUGE %wa value, which as far as I know means a network or disk bottleneck. ifconfig shows no dropping packets and there's not a ton of bandwidth going on, so that leaves disk issues, right? There's not a lot of disk writing going on either...iotop is reporting we're only writing a little over 1 MB per second and the RAID tool reports everything is A-OK and write caching is enabled. How do I go about trying to figure out how to fix this? UPDATE: iostat -x output is: avg-cpu: %user %nice %system %iowait %steal %idle 0.62 0.10 0.31 9.65 0.00 89.31 Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 0.21 33.34 83.55 16.54 1599.94 399.07 19.97 43.21 416.98 3.71 37.13

  • CPU Temperature required for auto-shutdown.

    - by ULTRA_POROV
    At what temperature do most motherboards/cpus power down to prevent damage? And what determines this? Is it the bios, the motherboard, the cpu itself? I have a cpu that stays on in the bios until about 105 C and then shuts down. I am not sure if this is correct? Maybe the sensors are wrong. I think 105 is a bit high. I guess 80-90 would be more reasonable for an auto shutdown.

  • CPU Lockup when loading folder of bookmarks in Firefox

    - by Gary M. Mugford
    I am running Firefox 3.6 on WinXPSP3 on a duo Core machine with 4G of memory. I am also running Avast! free anti-virus and ZoneAlarm free firewall, both latest versions. Within the last month, my service provider basically forced me to upgrade to a Docsis 3.0 compliant modem (offered me a deal I couldn't turn down). At that point, I also upgraded to FF3.6. Basically, I am not unhappy with many aspects of this switchover, EXCEPT, when I now load a folder of bookmarks (anywhere from 10 to 38) I get nothing like the load times I experienced a couple of months back. It's taking minutes rather than seconds. And the first bookmark in one of the folders, GMail, rarely loads before timing out. I have used the old trick of powering off the cable modem before my day's work. This used to fix 'load-lag' in the old days. I have switched from my ISP's DNS server to Google, OpenDNS and back. And nothing seems to work currently. It's not my DNS cache. That's been flushed and secondary computers also have the same issue when loading folders. I have watched the CPU usage and loading the folder will send VSMon (ZoneAlarm) usage over 40 percent, AVastSvc (Avast!) over 30 and Firefox will then push the needle to 100. There's a brief burst by SVCHost when the others falter in devouring cycles. Then everything subsides to single digits once the last tab is loaded. The only other nominal nastiness is VSMon ALWAYS hitting 50 percent when ANY program starts downloading content from the internet. If I shutdown ZoneAlarm (and VSMon with it), the same slow loading takes place, but this time System is running 50% plus, again driving the usage to 100 per cent. I have my doubts FF3.6 vs FF3.5 is an issue, since the other computers are still running 3.5 and suffer the same issue. Those computers are on, but inactive, most of the time, being backups. Obviously, when the CPU hits 100, I can't do much of anything in FireFox OR in other programs. Video play through WMPC or VLC is extremely choppy, although it doesn't seem to affect the audio. Any ideas what I can try next? Thanks, GM

  • How to resolve high CPU + excessive stat("/etc/localtime") and clock_gettime(CLOCK_REALTIME) calls

  • CPU sometimes hangs at 50% maximum on Windows 8

    - by Martin.
    Recently I installed Windows 8 on my HP ProBook 6450b and it appears I've got problems when using more than one program at once. Sometimes, when I run multiple programs at once, CPU hangs at 49% and never goes up. I suspect it has something to do with CPU throttling, because sometimes it just goes over 49%. I've got my notebook connected to charger and my plan is set to "Active cooling". The weird thing is that this happens only occasionally. I found nothing in my BIOS that could change this kind of things.

  • CPU and HD degradation on sourced based Linux distribution

    - by danilo2
    I was wondering for a long time if source based Linux distributions, like Gentoo or Funtoo are "destroying" your system faster than binary ones (like Fedora or Debian). I'm talking about CPU and hard drive degradation. Of course, when you're updating your system, it has to compile everything from source, so it takes longer and your CPU is used at hard conditions (it is warmer and more loaded). Such systems compile hundreds of packages weekly, so does it really matter? Does such a system degrade faster than binary based ones?

  • CPU clock scales down so computer is unusable after switching to battery

    - by Ryan
    When I am plugged in my laptop runs great however when I unplug it and I'm on battery power my CPU clock speed scales down pretty much all the way. I know this is happening by monitoring the clock speed. When plugged in it will usually stay between 1000MHz and 3000MHz but when I unplug it it quickly scales down to less than 500MHz and will get as low as 100MHz and it will NEVER scale up at all on battery power. After I plug the power back in it will then begin operating normally in about a minute. I have tried setting the MIN and MAX CPU performance in power options to 100% and have tried messing around with cooling settings which seemed to be a problem with HP laptops. I have a Toshiba Satellite M500-ST6444 running Windows 7. The BIOS is up to date. I have tried two versions.

  • Package temperature above threshold, cpu clock throttled

    - by drN
    I am running 64 bit Ubuntu 11.10 on an i7 with 8gigs of ram. I thought of putting this on askubuntu.com but decided that maybe the question has a much broader appeal. I have the following error message popping up when I run math simulations. CPUn: Core temperature above threshold, cpu clock throttled (total events = xxxxxxx) CPUn: Package temperature above threshold, cpu clock throttled (total events = xxxxxxx) I realize that this is a hardware warning message (machine check exception, correct me if I am wrong). How do I turn these messages off? Since it doesn't seem to have a detrimental effect of my calculations or my computer (presumably), I don't like it cluttering up my virtual console screen with hundreds of these messages.

  • Setting CPU cores off-limits to all threads not specified (preferably in Windows 7)

    - by Shinrai
    I have a really specific machine configuration in the works that would really be helped out if there were any way to do this...basically what I'm looking for is the opposite of setting CPU Affinity for a process. I want to be able to tell Windows "No applications except [x] are allowed on [these cores]." Is there any mechanism whatsoever for doing this? (Yes, I am aware of some of the potential issues this could cause and I normally would never fool with processor affinities, since the OS usually does a damned good job itself, but this is a pretty odd situation involving some software that is very CPU-bound constantly having to wait on interrupts and DPCs and things from other threads.)

  • How does landscape calculate memory usage?

    - by David Planella
    I'm trying to debug an OOM situation in an Ubuntu 12.04 server, and looking at the Memory graphs in Landscape, I noticed that there wasn't any serious memory usage spike. Then I looked at the output of the free command and I wasn't quite sure how both memory usage results relate to each other. Here's landscape's output on the server: $ landscape-sysinfo System load: 0.0 Processes: 93 Usage of /: 5.6% of 19.48GB Users logged in: 1 Memory usage: 26% IP address for eth0: - Swap usage: 2% Then I ran the free command and I get: $ free -m total used free shared buffers cached Mem: 486 381 105 0 4 165 -/+ buffers/cache: 212 274 Swap: 255 7 248 I can understand the 2% swap usage, but where does the 26% memory usage come from?

  • Windows 7 Reading Proper Disk Usage Statistics on Mounted Volumes

    - by Troy Perkins
    I'm running windows 7 with 2 x 1.5 TBYTE Drives. The second internal drive is setup as a mounted volume as C:\Archives Clicking computer icon in windows explorer, it only shows capacity stats for C: and Not C:\Archives Also, the usage stats that do show for C: show to be 100% capacity red - yet the system runs fine. No warnings. Can someone explain this? I do have a lot of stuff on the c: drive, but I'm sure its not 1.5 TB worth and C:\Archives hardly has anything it. Thanks! Troy

  • ngen.exe is constantly using CPU

    - by teedyay
    I recently installed Windows 7. This was a clean install (i.e. not an upgrade from another version of Windows), but I did install a bunch of other programs. All mainstream applications - nothing wacky. Since then, my CPU usage has been constantly at around 50%. Task Manager shows me that ngen.exe is the culprit. It's not a long-running task: I can see that it gets a new PID at least once a second, so I guess something is constantly triggering it. It does it all the time, even when I have no applications running. Has anyone else seen this? How do I find out what's causing this?

  • What is meant by the terms CPU, Core, Die and Package?

    - by lovesh
    Now this might sound like too many previous questions, but I am really confused about these terms. I was trying to understand how "dual core" is different from "Core 2 Duo", and I came across some answers. For example, this answer states: Core 2 Duo has two cores inside a single physical package and dual core is 2 cpu in a package 2 cpu's in a die = 2 cpu's made together 2 cpu's in package = 2 cpu's on small board or linked in some way Now, is a core different from a CPU? What I understand is there is something that does all the heavy computation, decision making, math and other stuff (aka "processing") is called a CPU. Now what is a Core? And what is a processor when somebody says he has got a Core 2 Duo? And in this context what is a Package and what is a Die? I still don't understand the difference between Core 2 Duo and Dual Core. And can somebody explain hyper-threading (symmetric multi-threading) too if they are super generous?

  • The best software for users internet usage

    - by nikospkrk
    Hi, We are a small business using a Vigor 2820 as the internet router, and we'd like to install a software that could report any internet usage from our users. I already tried the "official" software made by Draytek called "SmartMonitor", but is reliability is a real issue as it doesn't seem to keep capturing packets after working 3 to 6hours (randomly), whereas Wireshark keeps capturing packets after that amount of time. As I'm really fed up with this tool, I'm looking for other solutions but I still want the same features: users statistics, websites ranking, users traffic, ... I already enabled the port mirroring feature, so it would be perfect if you could suggest me a port mirroring-based software (ideally freeware). I thought I had found the good one with Etherscout, but it just doesn't launch. I am even open to a tool that would "just" make some reports based on Wireshark captured files (*.pcap). Thank you for any of your suggestion, Nicolas.

  • wmpnetwork.exe service clogs CPU usage

    - by Brenton Taylor
    We have remote locations each with 2 ASUS media extenders that stream from a computer with a shared Media Player library. Lately, several of these locations experience the "wmpnetwork.exe" service throttling the CPU to 100% usage. Killing the service only results in it starting back up, and so far the only temporary solution is to uninstall Media Player. A lot of these computers are also about 3-5 years old. Could it just be a case of outdated hardware not being able to do everything we ask them to do? Edit: all running Windows XP and Windows Media Player 11

  • Caching DNS server (bind9.2) CPU usage is so so so high

    - by Gk.
    I have a caching-only dns server which get ~3k queries per second. Here is specs: Xeon dual-core 2,8GHz 4GB of RAM Centos 5x (kernel 2.6.18-164.15.1.el5PAE) bind 9.4.2 rndc status: recursive clients: 666/4900/5000 About 300 new queries (not in cache) per second. Bind always uses 100% on one core on single-thread config. After I recompiled it to multi-thread, it uses nearly 200% on two core :( No iowait, only sys and user. I searched around but didn't see any info about how bind use CPU. Why does it become bottleneck? One more thing, here is RAM usage: cat /proc/meminfo MemTotal: 4147876 kB MemFree: 1863972 kB Buffers: 143632 kB Cached: 372792 kB SwapCached: 0 kB Active: 1916804 kB Inactive: 276056 kB I've set max-cache-size to 0 to make sure bind can use as much RAM as it want, but it always stop at ~2GB. Since every second we got not cached queries so theoretically RAM must be exhausted but it wasn't. Do you have any idea? TIA, -Gk

  • TOP CPU usage for whole system

    - by heike
    I am using a machine that has using cat /proc/cpuinfo | grep processor | wc -l returning 8 I am trying to load the server using a load generator that I wrote, and capture the behaviour of TOP command for idle (as the software that is tested on server runs on ROOT). Doing the load as an increasing step function, I capture the idle state every second, and see the result. Strange thing is that when I increase the load every 1 minute, the idle state is infact increasing (??). This honestly does not make sense .. I thought with more load, the idle state will decrease, and the cpu usage will increase. Is there any reasonable explanation for this behaviour, maybe for the server utilization itself? Thanks for any feedback -- ok, no idea for the down vote. but I try to find this behaviour a lot, can not find any reasonable things to explain this ..

  • Why won't Windows use the other CPU cores?

    - by revloc02
    In Windows Task Manager the Performance tab shows the first CPU maxed out, the other 7 just idling along with the occasional spike. What gives? More info: I've got 8GB and only 4.5GB are being used. The Processes tab has no indication of any process hogging processing power. In fact System Idle Process is 98-99. When I program stuff and have like 8 to 12 applications going (several directly unrelated to programming of course) my computer slows to a crawl. Sysyem Info: Intel Core i7-2600K Processor (quad-core with hyper-threading), 8GB RAM, Intel BOXDZ68BC LGA 1155 Motherboard, 500GB HDD

  • Display CPU usage separately (without root privileges)

    - by synaptik
    I need to display the CPU usage for each processing core on a single shared-memory 12-core (SMP) machine. I don't have access to install htop, else I would simply use that. I don't need fancy graphs or meters, though they would be nice. For example, simply displaying: X X X X X X X X X X X X where each X is the percentage utilization of 1 of the 12 processing cores on my machine. FYI: I know I can simply look at the utilization in "top" and divide that number by the number of cores on my machine, but I prefer a solution that shows each core separately.
