Cant OC q6600

Hi there,

I was reading up on the internet and i saw that my Q6600 is pretty easy to OC from 2.4ghz to 3.0ghz.
So i changed to FSB 333 and Multiplier to 6 (333x6) but then when i did that, my pc just didnt even wanted to boot anymore or go into the bios screen.
After a few resets i got a screen that the 'Overclocking had failed' and it automaticly changed back to 2.4ghz.

So what did I do wrong?

  1. What do you have for a motherboard? You don't want to move the multiplier to 6, leave it at 9. Set pci-e to 100, and make sure your ram isn't running faster than they are rated.
  2. Set your ram to its lowest multiplier and you should be OK, unless you have a motherboard that doesn't have much overclocking room.
  3. Here's some details about my system

    Mobo: MSI P45 NEO-F
    CPU: Intel Q6600
    GPU: XFX Ati Radeon 6870 1024mb
    PSU: Coolermaster 620W
    Corsair DDR2 800 - 2x2G RAM
  4. As has already been said, set your PCIe bus to 100, your ram to run 1:1 and keep the multiplier at 9, that should get you ~3 GHz with your FSB at 333.

    You might have to do a slight bump of voltage, and as always do keep an eye on your temps.
    What heatsink are you using?
  5. A P45 motherboard should take you up to the ballpark of 3.5GHz.
  6. Just be aware of the ram speed. And I bet the computer boots, that is a noticeable overclock for that CPU.
  7. This link provides a little information on overclocking with a similar motherboard. The trick to memory settings is that different motherboard BIOS use different terms to achieve the same thing. From this link it appears that the right setting for MSI is simply 1:1.

    If your CPU is running at 3.0 GHz then your main bus is running at 333MHZ and your ram (because it is DDR, "double" data rate) is running at 667MHz. You can do the math for faster speeds- there is a small chance that your CPU would run at 3.6GHz, in which case your ram would be running at its full rated speed of 800MHz.

    If you google "msi q6600 overclock" you can probably find other people with the same motherboard and cpu that you have and see what their settings were.

  8. I cant find the setting on my mobo where i can set my PCI Bus to 100...(noob) :(
  9. My board is an MSI P45 Neo-F and according to my MSI Live Updater my Mainboard/Drivers/Utility are the latest version (1.10).

    I think i got an auto overclock function in my BIOS in a menu called 'Cell Menu'. But if i look there i can't find anything that says PCI Bus.
  10. Set overclocking or advanced, or possible it's called tweaker, to manual.

    May not be necessary. In that link I gave you above they didn't appear to change it either. You can skip this setting and try it.
  12. Meh it crashes again....
  13. As has already been said, set your PCIe bus to 100, your ram to run 1:1 and keep the multiplier at 9, that should get you ~3 GHz with your FSB at 333.

    Did that except the PCI Bus cause i cant find it but it still crashes? How to make my ram run 1:1 btw?
