    I have an Atom Z520 that I would like to overclock a bit. (Acer 751)

    I installed SetFSB and found the right clock generator.

    The upper slide says 160/760
    The lower slide says 325/760

    Now it's running at 1.26. I'd like to go to 1.33GHz.

    What should I do?

    Did you click Get FSB before you started?

    Higher is FSB which is CPU/RAM.

    Lower is PCI-express bus

    Use CPU-z to confirm frequency changes.

    Different PLL as this is for the Asus W90 but I made this as part of my W90 Guide

    Yes.

    Should I increase both? If so, which one first PCI or FSB? Or just one?

    Thanks I'm using RMClock. That works too.

    Just cpu/ram

    mess with your pci buss and your system will become unstable fast and you can even cause hdd corruption.

    Set FSB works off a 1:2 ram fsb ratio btw so if its not showing the correct fsb dont worry about it. If it is showing the correct fsb then you can easily set a particular bus speed by passing it to the app as a command line switch as per the manual. Unfortunatly for someone like me who has a 2:3 ratio i have to tell it 200 which is actually 266mhz.

    I cant really explain how the slider relates to anything, 397ish on myne is 200 aka 266mhz actual and 500 is about 306mhz actual.

    You can use something like wprime or go more extreme and that intel burn in app to test the stability. Not sure how the atom is with overclocking but with the C2D it seems like ram is the weakest link.

    Yeah RAM is the limit for me on my quad Q9000 also, Atom goes to about 1.8 for most people and very few manage 2.0ghz. Well this is for the 1.6ghz atom in the EEE, I did not know there was a slower Atom than that....

    Where would you get PLLs for specific notebooks? ie. a Dell Precision m6400?
    thanks,

    Start with the dell section of this website? Google, or rip apart the laptop and search for the clock generator chip to get the number off of.
