Well you are referring to me, because I said that. I meant total FSB which to me would be Quadpumped (seeing Intels have Quadpumped FSB's) and the total would have to be 2132. The Mhz of the FSB (not Quadpumped/total) would have to be 533Mhz indeed.
You'd have to up the voltages of both the CPU as well as the NB and maybe even up the voltage of the RAM to get it more stable. 533 is quite high...
Sorry for my bad explanation before, I should've explained more
EDIT: This is what I said exactly:
You're ram should run half the speed of the Quadpumped FSB if it's DDR2. Any more and you won't notice the difference (with Intels). So if you want to use the full extend of those 1066mhz.. You'd have to run an Quadpumped FSB of 2132... Which would mean your FSB would be 2132/4= 533... That's quite high.
So, I did explain correct but perhaps too difficult? I said your FSB should be: 2132/4. So FSB = 2132/4 --> FSB =
533
I did however forgot a "Quadpumped" in the beginning of my first sentence (it's in Italics now).
