Intel Atom N450 Overclock Tool
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

It indicated two CPUs (due to hyperthreading), both of which were 95% busy most of the time while the machine was connected to the Internet. When I subsequently ran the top and htop command, I found that the sum of all%CPU entries was typically between 20% and 15% on all my Linux Mint systems including this LM18.2 machine. C Thanks very much for your help in advance. 2017-08-27.
My important conclusive lesson: Accurate, meaningful measurement of CPU usage is best done with nmon and htop together on the same screen. Otherwise, data can be misleading when not cross-checked or interpreted properly.

While I firmly believe in the top command's%CPU output data, I fail to understand why this graphic program's output differs so drastically from that of the top command.
Thanks very much for your help in advance. Julianvb Can you post the output of the top command?
Jsbjsb101, Thanks very much for you quick response. I revisited the top command again a few minutes again with my LM18.2 online and offline. To my utter surprise, the online data from top agrees now with the graphic monitor's last night's output. I am attaching both inline and offline image files. Julianvb Your first top output (attached image) show that a process called 'Web Content' is using a LOT of CPU time, as well as firefox and the main cinnamon desktop environment processes, are your running any kind of server?
Since I need the browser as long as I remain online, does it in turn imply that high CPU usage is a natural consequence? New iobit driver booster pro key generator - software 2017. As far as I know it is. It is the price what you pay in 2017 for complete applications implemented in web pages and running in a web browser. I used to have a fanless Atoms as desktop machines as well, but I stopped using them because of this.
Linux and lightweight desktops easily run on atom machines, and just because of web contents I had to dump that idea. My sun had a fanfull Atom with temperature controlled fan. As soon as he started browsing his favorite sites his computer would sound as a vacuum cleaner - the fan trying desperately to cool off the CPU cycles induced heat. Quote: As far as I know it is.

Jlinkels Hi, jlinkels, Thanks very much for a clear-cut answer. I bought several $10 fanless Atom N270-based Jetway workstations with Linux Mint 18 pre-installed last year and was fairly happy with them. They are also known as mini-motherboard tabletops and weigh 5 lb each. I gave one to my nephew a few months ago and last night he pointed out this problem to me when he came to visit.
I guess his complaint is justified as he is used to the latest stuff and has more needs than a retiree like myself. On the other hand, I find these year-2013 fanless machines cool and quiet. As a matter of fact, my good old 2004 Compaq desktop running LM17.1 is also showing heavy CPU usage. I was unaware of this common fact until my nephew brought it up after he came home for the summer. Perhaps I'll find a happy medium compromise somehow? Your feedback will be much appreciated.
NOT installing flash and NOT installing java can make your browser less CPU hungry. But installed by default on a lot of desktop orientated installs. Using older things like xload to check the CPU usage is more entertaining than informative on modern multiple core machines. Using htop might prove less confusing. CPUs ramp up and down a lot these days to save power. Some of which is hardware based and hard to monitor in software. Even the output of /proc/cpuinfo changes depending on if your CPU is under load.
Perhaps your seeing the trend to run near 90% of your current CPU speed which changes speeds to maintain that number. And is otherwise not representative of the usage relative to the max capabilities of the hardware. Using nmon might also prove less confusing. $ nmon 'l' (lower case L) for cpu meter.
Perhaps I'll find a happy medium compromise somehow? Your feedback will be much appreciated. Julianvb I gave up. I purchased i7 fanless desktops for my wife and me, and an i5 fanless desktop for my son. They are definitely out of your $10 range.
The Atoms I use now as thin clients, or machines which have to run a task without GUI involved. Like monitoring and logging, backup server, whatever. My main file server is still an Atom. It is a shame that scripted web applications void the efforts of hundreds of open source developers who try to write lean and efficient software. (I learned software development on PDP11, IBM370 and HP1000. One knew better than writing inefficient scripts) jlinkels. Since I need the browser as long as I remain online, does it in turn imply that high CPU usage is a natural consequence?
It depends on the web pages you visit. Not all of them are so laden with javascript and CSS animation and sh!t. A good way to lighten the load is to install the noscript addon. For some sites you don't have to do anything, but for some you need to allow scripts (hit and miss) until the site becomes usable. Then you tell noscript to remember that.
You also need to clear cookies & offline data after you close the browser. you can also install the request policy addon, it works similarly to noscript. and of course you must have an adblocker; they also lighten the load.
The words overclocking and netbook appear in a sentence together about as often as Steve Ballmer is spotted at a Linux convention. Netbooks are all about portability over performance. Overclocking is all about taking already blazing-fast gear and pushing it to its upper limits - warranties, energy use and safety be damned. Actually, 'people have been overclocking netbooks pretty much since Day One,' according to Brad Linder, who writes the. It started with the, which Asustek Computer 'intentionally underclocked. To improve battery life,' said Linder. Frustrated hackers developed tools such as and to 'right-clock' the Eee's CPU, he says.
Quick to take a hint, Asus soon began shipping its own overclocking app, the Super Hybrid Engine, with every Eee. That let users while staying within warranty. And the newly released Asus 1101HA can be.
To comment on this story, visit. Netbook manufacturer MSI also enables its users to and make them as much as 24% faster. Then there are extreme modders like in Adelaide. Using a dry-ice-filled pot to chill the exposed motherboard of an netbook, they were able to push its Intel Atom N270 processor to 2.4 GHz, a 50% boost over its rated 1.6 GHz. Of course, most of us aren't interested in performing science experiments for the sake of bragging rights. We just want to get apps to load faster, or high-def videos to play stutter-free.
But besides Asus and MSI, few other netbook makers officially endorse overclocking, much less bundle tools to enable it. Never fear: Below we detail five (fairly) easy ways for you to overclock your netbook, none of which requires access to exotic cooling materials, and only one of which requires competence with a soldering iron.
(There's also a for Acer Aspire One owners - no overclocking, but plenty of hardware tweaking.) Here's the fine print: Most of the solutions require your netbook to be running Windows rather than Linux. And the finer print: Your netbook's battery life will definitely drop, while noise from the netbook's fan will rise. Your netbook could crash or freeze if you raise the speed - and temp - too high, too fast. And if you accidentally fry your motherboard using these third-party apps, don't expect your vendor to honor the warranty. Now, on with the overclocking!
Fiddle with your front-side bus with SetFSB Method: A free, open-source tool, Abo's lets you tune the speed of your CPU, memory and key controllers. Models: Virtually any netbooks running the Intel Atom CPU, including Asus Eees, and even Hewlett-Packard's Minis (more on that later). Not only can SetFSB work with netbooks, but it works for many laptops, net-tops and desktop PCs as well. The has the complete list of compatible chip sets and motherboards.
Operating systems: Officially, Windows Vista, 2003, XP, 2000, NT4, Me and 98. Difficulty level: Potentially challenging, due to the need to for your CPU and employ separate temperature-monitoring software such as. ODOC offers a, while NotebookReview.com offers. The scuttlebutt: SetFSB is widely considered the best multi-PC overclocking tool - when your hardware cooperates.
Dorothy, apart from the usual housekeeping (minimize startup programs, defrag the disk when over 10% fragmented, etc.) there is only one radical cure and that is to switch the disk for an SSD. That will cost you around $150 to $200, but it would make a BIG difference. If you are interested, let me know and I tell you the steps and the optimal choices.
There is nothing you can do with the procesor. It is a slow single core because of battery life and heat limits. A faster processor would have meant much shorter battery life and a lot more heat. And that is incompatible with the small box. The SSD also uses a LOT less battery than the disk you have and it produces no heat at all - unlike the spinning disks.
But next year things will get better. Then Windows8 supports ARM processors which will be ideal for the netbooks and they are a LOT faster. Those are the processsors they have in the tablets a la Apple iPad and Motorola Xoom - also in the readers a la Nook Color. The reply from WHS seems to hit the mark - you can't have a long battery life and a fast processor (yet). The starter edition of Win7 seems particularly slow. You may get a small speed advantage by increasing the page file to 4GB (it won't increase automatically when you upgrade to 2GB RAM) and also by allocating 4GB of a USB key for 'ready boot'. My hard disc scores 5.9 out of 7.9 under “Performance information and tools” and I'd be interested to know from WHS how changing to a SSD would speed up things.
There is an alternative easy way to speed up your netbook - switch to Linux. You'll be amazed how quickly it boots and shuts down. You can run Ubuntu parallel with Win7 and it will do just about everything Windows can do. You use Firefox, Open Office, VLC media player, Autokey etc instead of the Windows equivalents. It's very easy to set up and use, and does not keep asking annoying questions about whether you're sure you want to do this or that.
Best of luck, kaspin. In most common operations the CPU is not the bottleneck - it is the access time to the disk that makes the difference. This is, of course, different if you do e.g. Video encoding, CAD type work or heavy computing. That does not mean that your system will become a super performer with an SSD, but it will get a significant boost. When you are ready to buy the SSD, post back so that I can give you some advice which device to buy (and always on sale which is frequent e.g.
In the meantime you may want to read this little SSD migration guide I have made: You also need to know whether your current disk is 2.5' or 1.8' - the latter is rare but some netbooks were using them. The SSD has to be the same form factor. And the amount of GBs you want (check what you are using now). I use 90GB SSDs on my laptops. You can always offload large files to an external disk (of which you should have one anyhow for imaging) or a large USB stick (16GB sticks come for $15.95).
Contents. Overclocking CPU on Ubuntu Overclocking is not a recommended approach to improve the performance of the Ubuntu system if it is used in daily operations, as this would affect the stability of the system. However, since gaming in Linux becomes possible as more and more video games distributors release video games in Linux, one may wish to get better performance from the overclocked CPU, accepting the trade off of the potential loss in stability. This page describes how to overclock the Ubuntu system. Please be warned that overclocking may introduce permanent damages to your system, particularly by increasing the voltages. Do so at your own risk! Hardware The CPU can be overclocked in the configuration of the BIOS.
You need all of the below if you wish to overclock the CPU:. An overclockable CPU. An overclockable motherboard. An up-to-date motherboard BIOS which recognizes the CPU When all is ready, go to the BIOS configuration page by press (or some other key, which will be displayed to you at boot) when the system boot up.
Find and change the CPU overclocking settings, which should be named as 'CPU frequency', 'CPU multiplier', or similar. Save the changes and reboot the system. If you are lucky, the system should boot up as normal. If the system has no response, you may need to reset the BIOS (By rebooting a few times, shorting the reset pin, Googling, etc.) and test other overclocking settings. Verifying Intel Most Linux tools do not show the correct overclocked frequency. Fortunately, Intel released an official tool, turbostat, for this purpose. Below are the installation steps: 1.
Check the current kernel version, and install the required package. # uname -r X.XX.XX-XX-generic # apt-get install linux-tools-X.XX.XX-XX linux-cloud-tools-X.XX.XX-XX 2.
Install the MSR module. # modprobe msr 3. Open a terminal; run a CPU intensive application, here the OpenSSL speed test. # openssl speed 4.
Open another terminal; run turbostat to show the actual frequency # turbostat cor CPU%c0 GHz TSC SMI%c1%c3%c6%c7 CTMP PTMP%pc2%pc3%pc6%pc7 PkgW CorW GFXW 100.00 4.39 3.19 0 0.00 0.00 0.00 0.00 83 83 0.00 0.00 0.00 0.00 53.31 44.71 0.00 0 0 100.00 4.39 3.19 0 0.00 0.00 0.00 0.00 83 83 0.00 0.00 0.00 0.00 53.31 44.71 0.00 1 1 100.00 4.39 3.19 0 0.00 0.00 0.00 0.00 75 Column 'GHz' is the actual frequency the CPU running. Column 'TSC' is 'timestamp counter' the CPU reported normally running. As above shown, the CPU is reported normally running at 3.19GHz while is being overclocked at 4.39GHz. Column 'CTMP' is the core temperature of the CPU core. The core temperature can be used to estimate the Tcase temperature to see if the CPU is overheating or not. Below is a rough formula for temperature estimation: CTMP = Tcase + 15C The Tcase temperature of Intel CPU can be checked.
In this example, Maximum Tcase of the CPU is 72째C, as a result Maximum CTMP is projected be roughly 87째C. The reported reading 83째C is below the threshold. If the CTMP is too high, you may wish to lower the overclocking frequency or acquire a better CPU cooling fan to avoid overheating.
