The Sonoma Pentium M CPUs (with 533 Mhz FSB) cannot be overclocked at all. The previous Dothan Pentium M CPUs (with 400 Mhz FSB) can be pin-modded and so overclocked by 33%, but the higher frequency Pentium Ms (2 Ghz 755 & 2.1 Ghz 765) can't maintain the overclock within the chipset voltage limits and only some 1.8 Ghz Pentium M 745 CPUs can handle the overclock within voltage limits. If you can find a P-M 745 that is guaranteed stable (i.e. has been successfully pin-modded before), then you can get that and it will overclock to 2.4 Ghz, which is the absolute highest frequency attainable by a Pentium M processor. However, it's safer to overclock a P-M 735 (1.7 Ghz, 400 Mhz FSB) to 2.26 Ghz. I did this on my computer and noticed an improvement from my previous 1.86 Ghz CPU, but I doubt you'll notice much of a difference between 2.13 and 2.26.
