Overclock A Samsung Np-n140
OK, so I finally cracked and bought a netbook on a whim.Of course, the first thing most people do when they get a netbook is find out how to overclock it, amiright?So, thanks to google and thread at Sammynetbook forums, that's what I did:CPU Overclocking1) Download SetFSB2) Choose CV179CNLG as the Clock generator3) Set the upper slider to 166/380 and hit 'Set FSB'. Cr 125 motors for sale. Voila, (12 x 144) 1723Mhz Atom.I've played with other speeds, but I can't get it stable at 170 (it locks the screen after a while).

Overclocking experts from Team Australia, using an ordinary MSI Wind U100 netbook and a single Kingston 2GB DDR2 667Mhz SO-DIMM, have done the unthinkable, overclock the hell out of an Intel Atom N270 netbook processor. If you remember, MSI recently released a v1.09 BIOS for the Wind that allows overclocking.
I'm also a n00b when it comes to SetFSB and the Atom platform - I'm not sure if dividers come into play or something, as most Atoms seem to get to 1.8Ghz without needing extra voltage.CPU hits a maximum of 37'C (Realtemp) with Orthos running two instances.Graphics 'overclocking':There's also a tool called GMABooster that sets the clockspeed of the GMA950 (and the 945 in these netbooks) to different speeds (default is 166Mhz). Some sites seem to have had decent (20%) gains from it, but I can't see any difference.Using GMABooster, I set the graphics to 400 Mhz and ran 3DMark2001 (a fair benchmark I would have thought, given the hardware). It scored exactly the same as when set to 166Mhz (3034).Clocking the CPU to 1.72Ghz boosted the score to 3344 (10%).As for World of Warcraft, there's a possibility that I saw 1 extra FPS (+3%) when GMABooster was set to 400Mhz, but that could be just variations.
CPU speed definitely helped, again giving 10% increase.For those interested, WoW plays at 15 fps typically, with all settings on low @ 1024 x 600. Inside, you might see 30fps.
The CPU is the bottleneck.I also tried disabling Hyperthreading, as I know some software performs better on a single core, but this reduced frame rates a little.Having said all this, the performance in Windows in general is quite impressive! Once I cleared all the junk it came installed with, it boots much faster than my work laptop (Dell Latitude D610, Pentium M 1.7Ghz, 2GB RAM) and is very responsive.
