Is it possible to overclock a pentium m 915gm processor? I have one in my XPS Gen 2 @ 2.13 ghz and want to push it further, any help plz.

You can't overclock the 915 PM's but you can buy another PM off ebay and pin-mod it but even that won't get you much above 2.26GHz

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.

The Dothans were the 400/533 and the Sonoma was the platform consisting of the Dothan CPU. The Banias was the earlier P-M which was 400 MHz only I believe. So, if you had a chipset originally intended for Banias, then pinmods aren't really an option for you. Anyway, your chipset does support 533 MHz so you can buy any 7x5 CPU with 400 MHz FSB (these are dothans) and make them run at 533 MHz FSB via pinmod. The highest thats ever been attained in a laptop is 2.0 -> 2.66 GHz with a voltmod. There are a few 1.8 -> 2.4 GHz which haven't needed extra voltage as far as I know. However, these CPU's don't have a high likelihood of working with a pinmod even with the extra voltage. The P-M 1.7 -> 2.26 and 1.6 -> 2.13 are the most popular options.

Essentially, you aren't gonna get much of an increase even if you got the SL7EN (aka P-M 745) which is the 1.8 GHz P-M at 400 MHz FSB and were able to OC it. You'd face the risk of wasting that money so if I were you I'd just try to be happy with the P-M you have now. It is actually faster (from my own tests) than my Core 2 Duo at certain applications.

That surprises me, since the numbers I've seen show the Core 2 Duos to be better in pretty much everything. What applications run better with a Pentium M?

Vdub (well about equal) and rar'ing....see my signature under comparison numbers.

cool, thanks! hey, that means that I can say my 2.26 Ghz Pentium M can beat out the modern CPUs at something!
