Saw this post on another board: http://www.thetechrepository.com/showthread.php?t=30

It's been linked from here a few times.

Problem is I have no idea what the hell is going on after reading the post. Can anyone explain this real slow like for me? Is it basically saying at certain clock speeds the chipset drops speeds down to make the northbridge not overclock, thus reducing performance? Is clocking my FSB at 334 instead of 333MHz going to kill my northbridge because of this?
 
After 400mhz FSB the chipset applies the 1333mhz strap, reducing performance (but allowing higher overclocks)

closer to 450FSB your performance is equal to that of the 1066mhz strap (399mhz FSB and below) with the added bonus of a faster CPU.

To be very brief and only somewhat accurate :p
 
So the strap doesn't apply to anything under 400 (i.e. running at 350, 360, 372, etc.)? Like OP asked - no harm to northbridge running at 334 versus 333?
 
Yeah the graph in that article is confusing because it has labels like "max chipset speed" and it also shows the clock speeds dipping every 33 or so MHz on one of the lines, so I am not sure what's going on. Is it just < 400 MHz on Asus 965 boards or all 965 boards?

Also I have no idea what a strap is. The article just uses the term without really defining it.
