Im not sure how much you can overclock this processor? but I like to play high end games all the time & I also leave my computer running 24/7 so looking for the right settings & I also need some help this is first time overclocking!!

  1. This article is a bit old, but absolutely applies to your situation:,2396.html

    Basically it involves raising the reference clock to raise CPU frequency since you have a locked CPU multiplier. Trickier than with a black edition, but it can be done.
  2. BTW, you're at 3.2 so you should reach 3.6 fairly easily before you need to add any voltage. I don't know how much more you can expect with a locked CPU, often its the motherboard that detirmines how high you can go with your reference clock, although the Gigabyte board should be satisfactory.

    You may wish to look at a black edition CPU for further overclocking potential.
  3. Drop your RAMs from 800 to 667
    Drop your HT Link from 10x (2000MHz) to 8x (1600MHz)
    Lock PCIe to 100MHz
    Leave NB/IMC at 10x (2000MHz)
    Bump NB volts to 1.25v
    Drop CPU multiplier to 15x
    Raise Clock (FSB) to 240MHz
    Set CPU volts at 1.4125

    Step back - she's gonna take off.

    edit: I fergit ...

    Read your manual, and you will learn to hit Ctrl-F1 to expand menu options ...

  4. Ok Wisecracker lol I have done the settings you told me to try out & its shows that I have a 3.0ghz instead of 3.2ghz dont see nothing going up the ghz?? The cpu volts I can only pick 1.4250 I think!!
  5. Buzznut lol How much ghz can I go up to I think i got it up to 3.8ghz before but i was having trouble with things running it on idle i got 48 temp!! & Wisecracker when i set the FSB to 240 what does that make it 3.8ghz or something?
  6. HT Link = 8x240MHz
    IMC/NB = 10x240MHz
    RAMs = 6.67x240MHz
    CPU = 15x240MHz
  7. Yep that what setting I set it too & Will i notice if it overclock or not on the system properties on my computer? On the Cpu at 15x 240mhz what does that make it 3.8ghz?
  8. Hey Wise Thanks for helping me bro & you other guys also!! Hey wise is there any way I can overclock up to 4ghz? I was woundering if I could or not?
  9. Hey Wise you every gonna respond back lol I set the cpu i think at that settings it shows
    core voltage 1.456v is that what it needs to be set on?
  10. Best answer
    Every chip is different --- if you ask me a direct question I'll do my best to answer it.

    You need to report all your settings or give us a few screenshots to look through.
  11. Ya well I really dont have any problems till you came threw & help me out lol thanks bud so far my computer has not had a problem since you told me to setup the computer like that is there anyway that I can overclock my cpu at 4ghz? I heard someone got the chip at 4ghz & his idle speed was 48 degrees!! the settings that you gave me is that a 3.6ghz or something?
  12. How can I post pic on this? This is the first time i been on this website

  14. You need to establish an account at an image hosting service and upload your pics to their site -- use Ctrl-Shift-Prt Screen for capture. You may then link to the images at the hosting service using the 'picture command.'

    15x240MHz = 3.6GHz

    Your system clock at stock is 200MHz with a 16x CPU multiplier, or 3.2GHz. You have the '15.5x' and '16x' multiplier available to further overclock your CPU while keeping your RAMs at spec speed 6.67x240MHz (DDR3 1600).

    But first you should monitor for stability, voltages and temps. Here are your CPU specs. Blowing past these specs may eventually harm your processor.

    Past Gigabyte motherboards have shown a tendency to over-volt so it is important for you to experiment with your voltage settings. You should be able to raise and lower your CPU volts in 0.0125v increments. Stability at the highest clocks and lowest voltages is where you want to be.

    When you find extra voltage increases add little to clock speed increases (other than heat) you have hit the 'volt wall.'

    With experience and patience you can hit 4Ghz but you should first concentrate on getting to know your system and settings at the 240MHz clock. It's a 'sweet spot' with your RAMs.

    Try to upload some sceenies and we'll go from there ...
  15. Thanks Wise for all your Support Man You R Good of what you do I also just got me another computer do you think you can help me out with this one here is the link Im in need of settings this nice computer up
