Do you provide connector to link the two AA5 boards together?
P.S. Are the AA5 PT enabled?
I don't have a connector on hand. Based on the photos I've seen of it and the spacing of the pins, my local electronics superstore actually has the proper components (very cheap). The connections appear to be straight across between the boards with no crisscrossed pins. I would want to get positive confirmation of the the connections between the two boards from another owner of a dual board setup.
Edit: At first I didn't know what "PT" stood for, but I see that it stands for Performance Trilinear technology. The answer is yes, both boards can render two pixels per clock cycle. In fact, the designation 8232SB actually means 2 pixels per clock cycle, 32 MB of ram on each chip, single board (SB) config.
With two boards combined, the designation would be 8432DB. The one downside to SLIing two together is most games won't run using the WickedGL miniport driver. I believe I read somewhere that only Quake 1 will run correctly in this config.
With the single board, I can run almost any OpenGL game that is compatible with the 3Dfx miniport driver. I actually did some tweaking of the registry and installed the final set of drivers that allowed me to unlock the AA setting. The board to run with AA completely disabled, which results in near 8X sli mode (or close to it). On my Pentium 4 2.66 Ghz motherboard, It's about 4 times faster than a V5 5500 in Quake 3. It's going to be CPU limited with the original 1 GHz P3 motherboard that came with the SX.
