Now that I have my Voodoo2 cards working properly in SLI mode on my Windows XP system, I've been experimenting with them a bit.  One thing I've discovered is that overclocking the cards doesn't impact the frame rate of games or demos!  I've clocked them as high as 105 MHz to no effect.  I am, of course, rebooting after making the change in the control panel, but there is still no change in speed.

Powerstrip reports the speed as matching that set in the control panel, but only after a reboot of course.  Also, Powerstrip allows you to make a change immediately without rebooting, but there is still no change in game or demo framerate.

Any ideas as to what may be happening?  Is this because of the SLI configuration perhaps?  (Powerstrip shows both cards in the "Options.../Adaptor information..." window, but it only has one entry for "Performance profiles ->/Configure...".)

I've read that the keypress combination CTRL-F9 can be used to toggle the passthrough function on Voodoo2 cards.  This would be useful to get back to the desktop when a Glide program crashes, for instance.  Of course this doesn't work under Windows XP.  Does anyone know of a small program that could be used to accomplish the same thing?

Thanks
