barton1G+epox+8RDA3I(nforce2 ultra 400)+msi geforceTI500+two monster 3d II(one is REV.B and the other is REV.E)+diamond mx400+DDR 256M

simple.try running some game in the 1024*768 resolution.preferably some glide game,such as unreal,deus ex,etc.if the 1024*768 resolution works,your voodoo2s are running in SLI

do you  have another way to check if these voodoo2's working on SLi?
because I have no these games,i only have diablo2 and the nfs2.and I find that if I set the vsync off ,the frame is double.can anyone explain this , thanks!

just download UT or deusex demo from somewhere and try it.

QuoteI find that if I set the vsync off ,the frame is double

When the vsync is enabled, the frame rate is limited to the refresh rate (60 hz, 75 Hz ..)
