To sum it up, the mod does not alter the memory bus, it enables an extra 4 pixel pipelines. To convert a 9500 to a 9700 the board must already have the 256-bit bus (which the 9500 128 Meg non Pro already has).
9500 64 Meg (non-pro) = 128 bit bus (because 1/2 the memory chips are missing though it uses the same PCB as the 9700)
9500 128 Meg (non-pro) = 256 bit bus
9500 Pro 128 Meg = 128-bit bus (not possible to convert because the PCBs are physically different, but it beat a unmodded 9500 non pro because the non pro only had 4 pixel pipelines despite the 256 bit bus on the 9500 non pro)



they assemble the RADEON 9500 on the same 9700 model with the memory chip "shortened". It's possible that they use graphics processors that failed to work at the frequencies specified for the RADEON 9700 Pro, because the 9500 is to be clocked at 275 MHz against 325 MHz of the RADEON 9700 Pro.
