Got an ATI Radeon 9600SE for x-mas. However, when I opened my computer up I found that my AGP slot is 1x,2x and the new card will not fit. The new card states 4x/8x. Any suggestions on what I can do to upgrade my graphics so I can get directx9.0 and enjoy some of the newer games. My system is about four years old, HP 8770C, 850mhz.
There may be a more-universal card with the same graphics chip. The differences between2x, 4x, and 8x is in the signal voltage.
The card supply voltage is universally 3.3V, no matter what the bus speed..
The signalling voltage is 3.3V on 1x/2x modes, and 1.5V on 4x mode. 8x mode uses a reduced voltage swing of 0.8V.
By definition in the AGP 3.0 specification, 8x cards and boards must always also support 4x.
Here's a couple of ATI reference charts:
