Why this thread? Simple answer: you can amazingly overclock the shit out of it (it may not be a big shit , but still).

Introduction :

Intel Atom is the brand name for a line of ultra-low-voltage x86 and x86-64 CPUs (or microprocessors) from Intel, designed in 45 nm CMOS and used mainly in netbooks, nettops, and Mobile Internet devices (MIDs). On December 21, 2009 Intel announced the next generation of Atom processors, including the N450, with total kit power consumption down 40%.

How can I overclock (or downclock) my Atom processor?

By changing your bus speed in your BIOS or use a program like ASRock OCTuner :
http://www.asrock.com/feature/OCTuner/ (http://www.asrock.com/feature/OCTuner/).

Note : you might need to change some .ini files or modify other files to get ASRock OCTuner working,if your motherboard isn't supported supported by default. These files could be found on the internet. Just google : overclock [your netbook]. E.g. : overclock HP mini 311

Simply set the multiplier (called CPU ratio in ASRock OCTuner) to the highest value available and raise the bus speed (called CPU frequency in ASRock OCTuner).

Overclocking my Atom N270 ,which runs at 1,6Ghz, to a stable 1,8Ghz was very easy by raising the CPU frequency from 133 to 150. It's really simple and I really noticed a difference.

After a hacked BIOS was released for my HP Mini 311c , I could change my bus speed in the BIOS and I got a much higher overclock. I'm now running 2Ghz stable with a 5:4 ratio.

FAQ :

Q: Is a higher CPU speed really noticeable ?
A: Yes ,for example in my case my netbook boots much faster, also things like browsing goes much more fluently.

Q: Does overclocking increases my battery life?
A: No (at least in my case) , this can simple be explained because you don't adjust any voltages.

Q: Can overclocking overheat my CPU / netbook?
A: This might be possible but is very unlikely because you don't change your CPU's voltage.



So TPU members i'd like you to share your Atom overclock experiences!

When I was running a EeePC 1005HA and was able to use SetFSB for clocking, I remember in the boot options for windows, enabling PCI Lock helped me get 2GHz run more stable on my N270. Haven't been able to find anything that can OC my 1101HA with a Z520, although with the built in OCing, running it at 1.7GHz instead of 1.33GHz is a big difference. Throwing a SSD in makes for major help on a SLOW CPU, even a bit under powered for XP without the SSD.

EDIT: Pic for help, its off my i5 650.

_FBi;1789612']atom's are x64 now?

The Intel Atom 200 series (not to be confused with the N200 series, widely used in netbooks) and Intel Atom 300 series have 64bit support :)

this also relies a lot on the Netbook's motherboard. Some are easy to work with some are not, Im going to try this on my acer aspire one d150 later.
