The Intel Atom processor is a great little processor that you'll find in almost any netbook, in addition to many custom-built home theater PCs, nettops, and other low-powered machines. The problem is, it can be a little to slow for comfort. Overclocking the Atom—that is, running it at a higher speed than originally intended—can give you a bit more speed and power when you need it, so it's a handy skill to have.
And, luckily, it's often easier than overclocking the Core i series , so it shouldn't be too hard to do, even if you've never overclocked before. Of course, the Atom still isn't the most powerful chip around. Overclocking isn't going to win you any speed contests, or make Crysis run beautifully on your netbook sorry.
However, I've noticed that my machine definitely feels a bit snappier. Apps don't launch quite as slowly, files don't take quite as long to load, and it took emulated Nintendo 64 games from "unenjoyable" to "smooth as butter". Of course, all of this depends on your particular machine and graphics chipset, but the point is that it can yield some nice benefits for a machine that's currently feeling a bit too laggy.
Relax and be free from anxiety Take back good sleep and help alleviate pain. There are, of course, some downsides to overclocking. Not only can it make your computer less stable if done improperly, but it can also damage your processor if you push it too hard.
In addition, it will undoubtedly decrease the battery of your netbook. So, in addition to showing you how to safely overclock your machine, we're also going to show you how to easily switch back and forth between the stock speed and your overclocked speed, so when you don't have an outlet nearby, you don't have to needlessly waste your battery.
Note that these next steps can vary a lot between different versions of the Atom chip and different motherboards. I recommend you Google around and see if anyone's done a motherboard-specific guide. Look through forums like overclockers. As I said before, I even found helpful information in the review for my motherboard on Newegg—a lot of people will post how easy it is to overclock a specific board, and what speeds they were able to reach.
This will give you a basic overview of the process, but if you find any specific guides for your motherboard or netbook, make a note of anything special that I didn't mention here.
Most of the guides you find won't be step-by-step like this, but they will mention any special things you need to take into account for that machine. If you're lucky, your machine will have some overclocking options in the BIOS; this is the easiest and most reliable way to overclock your machine.
Not everyone has this option, but you'll want to check before you move on to option two. To find out if you can overclock through the BIOS, reboot your computer and hold the setup key as it boots—usually this is the Delete key, though it could also be something like F2 your boot screen will say "Press DEL to enter setup" or something similar. For me, they were under the "JumperFree Configuration" menu in the "Advanced" tab.
It should look something more or less like the screen to the right—note that all BIOSes are a little different, so your screen won't look exactly the same, but you should have some similar options available.
If you don't have any of these options, you'll unfortunately need to skip to Method two below, which uses software to overclock your system. If you do have those options in the BIOS, though, read on. Some of you may have a "load optimized CPU OC setting", or something similar—these are actually overclocking options built into the board. All you need to do is choose a percentage value or choose a CPU speed from this menu, and your motherboard will do the rest. If you only want to overclock a little bit, this is fine, but I found I was able to get my system past these values by doing it manually.
And, to do it manually, we need to tweak a few settings first. Poke around the CPU menus and see if your processor supports hyperthreading. Turn that feature off if you have it, as it can really increase your temperatures. Disabling it will allow you to get a higher overclock, though if multitasking and number of cores is more important to you than the clock speed, you can leave it on—you just won't be able to overclock as high. Also, scroll down to your Vcore setting and take it off Auto.
But there is a category of portable PC that has its own specialized overclocking software: netbooks, more specifically EeePCs from Asus. On the latter, a frequency of 2 GHz compared the 1. It can also adjust the brightness of the display, the fan rotation speed, and the CPU voltage. You can find the latest version of EeeCTL right here. Current page: Overclock a Netbook? Page 11 of Overclock a Netbook? Overclock a Netbook? See all comments Interesting read although I doubt any real enthusiast would chose to overclock their system through software.
Much easier to get a higher stable overclock through the BIOS. Still, if you have a prebuilt machine with no BIOS overclocking functionality, some of this software is invaluable. Both great apps for overclocking your GPU. Good work trying to get the masses intrested in overclocking! Strangely for me, the opposite was true. The biggest hassle? Nonpaying users must redownload and install a new version each week. Those who donate any amount to the developer can avoid that hassle.
The scuttlebutt: Reports are mixed. Some commentators at UMPC echoed that sentiment. However, the French site Blogeee. The scuttlebutt: Extremely safe, since the speed is increased without boosting the voltage. For the same reason, any boost in performance may feel very slight, users say.
Method: HP puts a tiny pin on the motherboard of its Mini netbook to prevent users from overclocking it. Difficulty level: High. Twain had to figure out which "really tiny" resistor on the motherboard was doing the locking, cut out the resistor, and then use a soldering iron with a "super-small" tip to resolder the piece in a different location. Then he had to run the SetFSB utility.
For those handy with a soldering iron who are confident that they can follow Twain's pictures and instructions, good luck. Others should keep well away. His PassMark 7 benchmark score increased to Previously, his Mini could support only p. However, it does plenty of other handy things: turns down noisy fans, boosts the screen resolution up to by , from the native by and underclocks your CPU for longer battery life.
Models: Most versions of the Acer Aspire One, the most popular netbook today. The scuttlebutt: Reaction on the Acer Aspire One User Forum and developer Noda's blog has been frank about the app's bugs, but it's overall mostly positive. Noda released a final version, 1. Unfortunately, Noda says he has no plans to keep working on A1ctl, meaning no Windows 7 version or new features such as overclocking are coming, for now.
