Side band addressing (SBA) enables AGP to use 8 extra (Side band) address lines in addition to the 32 main ones to transmit requests for data, which should further improve AGP performance.
Sadly this has not been the case here, in fact I see absolutely no increase in performace whatsoever, over and above "NvAGP" "0", i.e disabling AGP altogether. If anybody has any ideas as to how I can improve the situation I'd be grateful.
For reference I have the following hardware:-
ASUS A7V8X Motherboard
Geforce 4 MX 440 64 GPU
AGP Rate: 8x
Fast Writes: Disabled
