How do I overclock HP Compaq?

  1. I'm having trouble overclocking my desktop. I can't find any settings in the bios that have anything to do with voltage and all the programs I've tried don't support the hardware. I've got a HP Compaq dc 7800p Convertible Minitower with Windows XP Pro SP3 on it.

    Most pre-built systems do not support overclocking so there are no options in the BIOS.

    If you want to get into overclocking build your own PC or buy a custom PC with hardware that supports overclocking.

    JMMD is right. But I know several years ago (haven't looked into it in years) there were some limited software overclocking methods. Perhaps those still exist.

    You may be able to do it using software, but it will be very limited.

    Can anyone recommend a software? BTW I'm willing to take a risk and burn out a piece of hardware (if that opens up options).

    Try clockgen.

    I run clockgen and this is what I get

    Can I change anything?

    Looks like you've got an "Intel® Core™2 Duo E6550 processor (2.33 GHz, 4 MB L2 cache, 1333 MHz FSB)" then, based on the configurations they list on their website.

    You could probably get 3 GHz on stock cooler, as many have been able to get over 3.3 with a little tweaking. However, I'd need to know your exact system specs to know how to proceed.

    List them, and I'll give you some instructions.

    @redk what would you like to know, my CPU clock speed?
    @UT66 what number should I enter?

    EDIT: if it's any use I've got a picture of inside of the case

    1) open your case 2) take a look at the motherboard 3) find the correct clock generator
    edit, i think your HP Compaq dc 7800p uses intel q35 chipset

    If you download Everest free edition, it should give all the necessary information needed.

    Try 425. Motherboard probably can't go up that high though. If it doesn't work or if you get overheating or BSODs under stress, clock it down.

    @Jskid what do you want to do with your pc? ( gaming, photo video editing, surfing) why are you unhappy with your performance? you know, you can do other things beside ocn you cpu, if your pc feels sluggish it might simply be a memory issue, how many things do you have on memory at once? how many process are you currently running?( one of my pcs is a ocd e7600 with xp sp3, doing nothing ( idle) it has a 82mb memory usage and 12 process running) just do a CTRL + ALT + DEL and tell me how many process do you see? start > run > msconfig > startup > what do you see?
    also you might want to try a different os ( ubuntu linux)

    @UT66 I often need multiple programs open. Outlook is always open, normally I have a web browser and Microsoft Office Product such as Word.

    thats fine,i also use a lots of programs at once, what i mean is if you have unnecessary process residing in memory all the time, as in sucking up your ram even if you are NOT using the application.

    When I run SetFSB from my computer I get an error saying WinRing0 Error5. If I run the files straight from the archive it sort of works.

    All the controls are grayed out and I can't click anything.

    i can't tell overclocking programs would work for the processor, but the NV 285 you're using will overclock nicely with nvidia system tools. (http://www.nvidia.com/object/nvidia_system_tools_6.06.html)

    I'd download that, and play around with upping the clocks. Don't save them to a profile until you've found a stable overclock though, or when you restart the computer it won't boot Windows.

    Also, if the motherboard supports it, the clock speed of the FSB (Processor related) will show up in System Tools. You might be able to OC the processor that way, as I have done with my C2Q.

    How do you use this program?

    See "System information", which is highlighted on the left?
    Click "Device Settings" above it. It might ask you to accept a license agreement or something of the sort, and then it may give you the opportunity to overclock various system parts. Some might be greyed out, but I know it works on the video card.

    Is this how it works? I make a new rule, define it, click ok, then click apply?
