Can someone explain about the "strap"?

From what I've read about newer systems, setting the strap is very important but nobody has explained why or how to do it. I've got an E4400 @ 3Ghz on a 965 mobo and didn't have any strap adjustments to deal with but for future OCing, it looks like I'll need to know. Can anyone advise me? Thanks.
 
Did you read some website translated poorly into English(or your language) and it came out strap? 'cause I haven't a clue what your talking about.

P965 do not overclock well with 800MHz chips. Most are good up to about 350 to 360MHz FSB. Get Abit IP35-E.
 
I believe he's talking about the FSB strap where the chipset loosens its internal timings (don't know the best word to describe it) as you clock up the FSB. Remember all those tests on the P5B-Deluxe when P965 first came out - they would test an OC at both, say, 400x8 and 401x8 - performance would actually fall at 401 because the memory controller's latency would increase dramatically at that point (where I believe the strap changed from 266 to 333).

My memory is failing me but I remember seeing several threads on this at XtremeSystems where folks graphed memory performance as the FSB was raised from stock (266) to 500 and beyond. Instead of a linear gain, performance would dip at certain points where the strap changed from 266 to 333/400. All those record-breaking FSB overclocks were possible because of higher straps (with looser timings) - something not seen on the previous 975X.

I am not sure how accurate my post is but it's roughly the gist of what I remember.
 
The FSB strap is what I was asking about. I'm satisfied with my current OC but for future rigs, I want to understand this a bit better.

if you have a lower FSB chip, you can pin-mod (pad-mod on Skt 775 technically... there are no pins on the processors) to a higher FSB strap. You technically can bump the FSB strap to 1066MHZ so it boots at a higher OC automatically and bump default voltage as well. Then you can also bump it to 1333Mhz FSB strap if you have a board that supports 1333 FSB. Theoretically you can OC higher on a higher FSB strap. Rather than topping out at 3 GHz with an E4400, you can OC to 3.4GHz or something.
 
Besides internal timings, some/most motherboard BIOSes also give you certain memory multipliers depending on the detected FSB.
