The cpu fsb is not as it used to be anymore.It's now more of a multiplier
working with the cpu multiplier and memory frequency.
Since with your cpu the multi is unlocked for at least the lower ones,you
can up the fsb as much as you want.
So where do you have to keep an eye on? Lower the HT5x to max 3x,because
this is multiplied with your cpu fsb (also HT frequency called)
And you won't go far beyond the result of 1000. 5x200 , 3x200 ,3x300=900,and
you get the picture.
So lower the memory frequency of 200 (which is actually a divider) to say
133mhz and with a fsb of around 307 you get your multiplier times that.
With this setting your memory will be around 200mhz again,running in spec.
This is just a simple novice overclock,you can lower the memory timings also
and use a higher divider for mem like 166 or 180.
Just keep in mind that the cpu fsb and memory fsb is on your cpu.And you
need to add some extra voltage to the cpu ofcourse.
Running at 3Ghz could be difficult if your mainboard doesn't support more
voltage then required.
You need some serious overvolt when trying to reach 3Ghz.
