    You can't overclock a oem machine... well at least not easily.

    If you want more info about your cpu open up a console and type in 
    cat /proc/cpuinfo
    It will display everything ubuntu knows about your cpu.

    Off-the-shelf, brand name computers usually will not overclock at all or will overclock only marginally. The operating system really has little or nothing to do with overclocking, unless the user is overclocking via a software interface. Most serious overclockers perform their tweaks via settings in the motherboard BIOS. Your Presario does not have overclocking options in the BIOS. I doubt seriously any overclocking software would work with your machine.

    Sorry, but big name brand companies leave very few options available in the motherboards' BIOSes. Additionally, in general, off-the-shelf computers do not have the necessary quality of components and cooling capacity for overclocking.

    I'm not trying to rain on your parade, merely setting out some facts.

    If you wish to do CPU (processor) overclocking, an overclocking-capable motherboard will probably not be sufficient. Other components as well might need upgrading:

    - computer case - needs to "breathe" well
    - CPU heatsink - overclocking creates additional waste heat, which must be removed from the processor
    - memory - depending on what overclocking technique you use, your RAM might need to have headroom, that is, the ability run faster than its rated speed

    It is my recommendation that if you wish to overclock, you should make that part of your planning for your next computer, whenever that will be. You will want high quality components that generally are not found in store-bought (or factory ordered) computers. It's not unlike someone wanting to turn a Dodge Neon into a high performance competition auto. Sure, it's possible, but it would difficult and expensive.

    Most overclockers build their own computers and pick components that they know will perform beyond their stated specifications.

    I can tell you from personal experience Ubuntu does not handle overclocking well. I have a AMD 64 3000+ Venice (Skt 939) processor cooled by a large Zalman copper heatsink/fan (applied with artic silver 5), low latency (2-2-2-5) Patriot Memory, a DFI Infinity Motherboard, and a 550 watt Antec Truepower power supply. Needless to say it was an EXCELLENT overclocker. I overclocked from the default 1.8 Ghz to 2.7 Ghz and beyond. I backed off a bit and maintained a good stable clock frequency at 2.6 - 2.7 Ghz. This was rock stable on Windows, no bad effects in any benchmarks or games.

    When I switched over to Ubuntu I was expecting some kind of amazing stability but instead it crashed all the time. So I posted on the Ubuntu forums criticising the hype about Ubuntu's stability and what I thought was its lack of stability. It goes without saying this topic drew a lot of attention and I was confronted my many Linux zealots (passionate crazy scientist types :p). However, I did get the suggestion to remove my overclocking. I did so and the crashes stopped completely and I experienced Ubuntu's superior stability.

    Ubuntu is a different system. It accesses system resources in different ways than Windows does and what is stable on Windows often isn't on Ubuntu. I do not recommend overclocking on Ubuntu. Not only can it cause unstability more easily than on Windows but unfortunately there is a lack of good 3d benchmark software. We do have Prime95 as a native way of testing the CPU for stability and we also have SuperPIE through Wine but 3d benchmark software like Aquamark, 3dMark, and PCMark on Windows I have not found on Linux. If I had the experience in 3d programming I would attempt to make one but unfortunately I'm a newbie programmer and I'm sticking to less ambicious projects.

    In short: I don't recommend overclocking on Ubuntu, it didn't work well for me and remember that just because your overclock is stable in Windows doesn't mean it is in Linux.
