Sideband Addressing, also know as Fast Writing is a way to speed up AGP transfer of data. Requests for data xfer are sent along additional data request path rather than wait fot the bus to come free before requesting.

I believe I read somewhere that at 2X and 4X it hardly makes a difference as the card is running about as fast as it can anyway. I seem to recall that it may have caused a reduction in performance in some instances.

I have a feeling that this function hasn't really caught on with the software industry because of the lack in performance increase.
