Question about FSB/multiplier

post #1 of 2
Thread Starter 
From what I've read, it sounds like an overclock should be the same at a certain frequency regardless of what you do to get to that clock speed. What I mean is, a stable CPU running at 3.0 GHz with the FSB at 500MHz and the multiplier at 6.0 should also be stable if the FSB was set to 600MHz and the multiplier were set to 5.0. These are not real numbers, but just an example.

Is this correct? I've just reached 3.32GHz on my Q8400 (415x8.0), but the system does not start up when I have it set to 3.15 GHz (450x7.0). It seems that my FSB is limiting me, not the final frequency, which seems strange to me.

I'm wondering if this is an normal because I plan on buying a new CPU cooler soon for the purposes of overclocking further, and if I'm unable to do so, I'd rather save the money.

Thanks in advance!

EDIT: Nevermind. I just read something that answered my question. I have two sticks of DDR2 800 that I am going to get rid of now.

EDIT 2: Nevermind. I took them out, but now I can't even reach 3.0GHz. What I saw was that my RAM was rated at 415MHz; meaning that was as high as my processor's frequency could go. Now, however, it says 533MHz and can't reach those speeds. What I read made sense of my first issue, but now I'm not sure what to do since I thought I fixed it.

When it gets to a certain point, you're more worried about your motherboard's FSB overclocking potential as opposed to your processor.

RAM should not be much of a factor as long as you watch the multiplier.
