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 feel silly for not thinking about this sooner, but I just now looked at my environment variables and found an entry that set the clock speed to 94 MHz. I can't remember how it got there. I probably put it there myself when I was trying to get the cards to work a few months ago.

In other words, nevermind. Help someone with a REAL problem. I'll be in the corner wearing a "dunce" cap if you need me.
