    Linux CPU Overclocking?

    I'm getting frustrated with finding information about CPU overclocking on Google. Could someone tell me straight forward just HOW to overclock an Intel 2.26 Ghz CPU? I want to boost it to 2.4 Ghz.

    For my nVidia card I just have a software app that I can set easily to overclock the graphics card, called nvclock . For the CPU I hear there are jumpers on the motherboard? What about software? Are jumpers the only way? Do most motherboards have jumpers?

    Jumpers are normally the only way to OC a processor. Most motherboards do NOT have these jumpers, especially Intel boards. Intel chips are also harder to overclock than say an AMD chip. Besides, your chip runs fairly hot and I'd hate to see what it does if you try and overclock it.

    Well I've got to become an ultra nerd. So if there are no overclocking jumpers on the motherboard, what other options do I have? Because I don't believe I have any BIOS options for overclocking or anything like that. Could try to flash the BIOS for the first time in my life...but I don't want to do that yet :[, I'm only level 2 nerd.

    Why flash the BIOS? It won't achieve anything overclocking-oriented (as far as I know). The only possible reason I could see you'd want to flash it is if you're one of those people who set a BIOS / System password and forget it...
    Good class architecture is not like a Swiss Army Knife; it should be more like a well balanced throwing knife.

    Some BIOSes (BIOSis.... I don't know how you say that) have the option to change the frequency multiplier, thus allowing for OCing. If you can find a BIOS for your board that does that, feel free.

    As Ahluka and Ober said, the BIOS, if your Mother board doest come with special software (OC Guru for Abit). Most BIOS have a whole section dedicated to the CPU, but if from some reason yours don't, then, they looking for software like Sandra but for linux.

    Also Intel seems to run cooler than AMD, or at least my P4 3.4Ghz ~ 3.55Ghz, runs cooler than an AMD 3800+ Venice.

    Intel use to be to top CPU manufacturer, but it seems to be behind now, i mean AMD's got 64bit, and PS3's got 128bit processors, What in the world is Intel so busy doing?

    best way to overclock is changing the multiplier,
    if that not a possiblity because your chip is locked
    or you just dont have good enough cooling,
    then you change yoru FSB up by 1 Mhz till you hit
    what you want and your still stable.

    As long as ive known p4 have run cooler then amd's,
    but then new amd athlon64, i know people who
    have over clocked them as much as 800Mhz, with
    standard cooling with no problems.

    Intel has the 64-bit Itanium, but it only runs 64-bit code. AMD has the Opteron, it runs both 64 and 32-bit code. Itanium is mainly for high end servers. Opteron is for the people and ...high end servers! lol

    I'm pretty sure that's correct, correct me if I'm wrong though.

    I'll check the BIOS again, I might've overlooked the frequency/FSB part of the CPU section. I'll also check the temp to make sure that's ok too.

    I'll try that technique! Thank you :]

    Alright I'll come back and tell you guys about my journey a little later.

    Alright I checked the BIOS and here are my temperatures:
    CPU: 51 celsius
    System: 34 celsius

    Now the only value to change numerically was the CPU FSB Clock. I changed that from 133 Mhz to 140 Mhz. The CPU temperature rose to 55 celsius. I guess I'll benchmark with glxgears, and then move it back down to normal 133 Mhz, and benchmark again...brb with some stat goodies.

    Oh jesus yes!!

    Just amazing!! The CPU temperature didn't rise that much either. 51->55->51. When I rebooted with the overclock the temp went back down to 51, hmmm! So I hear processors are happiest between:
    35 celsius -- 65 celsius. So I could perhaps overclock to 150 MHz FSB? What do you guys think? Maybe even 160 :], I could overclock to 2.5GHz :],

    too bad I couldn't do this with software though, because I only need this boost only when UT2004 is running.
