Testing the
Slipstream kit on a 3dfx Voodoo3 3000 card
Installation
of the Slipstream kit in the Voodoo 3 card was exactly the same
as in the TNT2 with the only difference that the 3dfx Voodoo3
3000 card only comes with a huge heatsink on the chip with no
fans on it, it used a thermal tape pad instead of thermal grease
and also the card came with 6ns memory.
Using
the original setting and heatsink I had already overclocked the
card to 175mhz which already was a considerable increase over
the original 166mhz.

However
after installing the Thermo Coupler the possibilities of getting
of bigger boost raised. I tried 185 and 190mhz and the system
wouldn’t hang up immediately but it showed a lot of garbage on
the screen first.
Finally
the best stable overclock I could get was 180mhz which is only
5mhz higher than what I could get with the original heatsink and
14mhz higher than the default settings.

From
what I experienced the Voodoo3 core could have run at a higher
speed unfortunately there isn’t an overclocking utility for
the Voodoo3 that let’s you change the core and memory speeds
separately so in this case I would sat the 6ns memory was the
limiting factor.
This
is really bad since I’m sure I would have been able to run the
card over Voodoo3 3500 speeds, anyway the 180mhz I was able to
get is only 3mhz away from that.
