    Ubuntu and Overclocking

    Well, it looks like I'm going to say bye-bye to Vista soon and hello Hardy! =D However, I do have a question. What is that best method for overclocking Ubuntu? I'm trying to avoid BIOS clocks, because my dad would throw a fit. I know there's gotta be some good softclocks for linux - anyone had any experience? What works best with Ubuntu?

    Thanks,

    SH

    For GPUs, the main ones are nvclock for NVIDIA cards or rovclock for ATI's Radeon.

    I'm afraid I don't know of anything for the CPU...I have a MSI board with CoreCell but never found any software to control it from linux

    if you hadn't droped vista you can overclock it from there with Nvidia Control panel (if you have nForce chipset)...

    Re: Ubuntu and Overclocking

    I've been into linux for about 9 months so I know enough to stay away from windows. I've just been learning things as I need them, which is fairly often. I'd be nowhere without ubuntu forums, and support. I don't know if you call it overclocking, I've been wondering what it's called and think it might be giving the same result. I hope someone can tell me if it's safe in case it burns out my cpu. Or someone else who tries it I'm using a HP dv9500t 2.2GHz with 4GB ram It seems well ventilated enough to avoid overheating.
    I went to Applications/System Tools/Ubuntu Tweak0.2/System/Power Manager/CPU Policy-performance value when on a/c. I found it when looking through the applications, and thought any tweak program should come in handy. I have no idea how well known it is.
    The default was a/c 85% on demand. I first increased it to 95%.with CPU frequency policy when on a/c at Performance. I'm folding@home. The work unit speed increased by about 20% I've kicked it up from 95% to 100%. At the moment the cpu is running about 60 deg C. Other programs and boot seem faster, but the FAH WU speed was a clear measure. I just found tweak 0.3.4-1, so that might be more useful. Hope it helps.

    Re: Ubuntu and Overclocking

    What's so wrong about fiddling around in the BIOS to overclock your CPU?
    (It's best to do this on a desktop computer, not a laptop).

    The very worst that can happen is that you won't be able to boot up without resetting the CMOS jumpers / re-seating the battery on the motherboard.

    Overclocking using software or the BIOS comes with exactly the same risks.
    And those risks are quite minor (unless you've got a laptop - they can have problems dissipating heat).
    Just so long as you know how to reset the CMOS memory you'll be fine.
    Work smart, not hard.

    Re: Ubuntu and Overclocking

    His dad would hear the beep-beeps and kick his a** . As for overclocking utilites in linux for CPUs, the are none! The only one was powertweak which I compiled from cvs a few years back when I had a Pentium MMX. If you have a 4 year old computer (or older), you can give it a try (probably it will not work, the last kernel it was tested on was a 2.5.x). Otherwise, use BIOS.
