RivaTNT2 32T - Page 4
After I griped about the miniscule installation guide, it
was strewn into a heap of waste paper lying about. There
really isn’t a need for one as long as you can loosen
couple of screws and correctly identify the AGP slot.
Then as all wise DIY-ers will
know, purge any old video card drivers from within your Windows
system before checking in the newcomer. Installation can only
be a breeze then. It was without a hitch for me.
The 300Mhz RAMDAC on the Aztech is more than sufficient for
my monitor, so there’s little to complain. Text was sharp
and clear with no noticeable difference from my PowerColor
Sniper TNT2 M64 (also 300Mhz RAMDAC). Admittedly, my Philips
17A cannot match today’s high-end boards to tell any significant
Right! There's no way we will spare it the pain! I opted for
the simpler TNTCLK 1.2 instead of PowerStrip to get the job
done. From a simple slider, the core and memory clock could
be modified easily.
To determine if the core/mem
setting is stable and reliable is never easy. If you overdo
the core, you will mostly experience a hard lock up instantly.
If it is the memory under stress, you will usually get severe
tearings and artifacts across the screen. In these conditions,
you know for sure that the card cannot make it.
In other situations, things
are a lot more deceiving. At any apparent stable speeds,
while you will encounter little trouble around Windows,
real trouble only shows up when you run graphics intensive
Cutting the long story
short, the Aztech TNT2 was left to be punished with an
hour’s worth of Q3Test on continual loop (using the
Set D1 "demo q3demo2;

I lost count on the number
of hard resets I put my poor system through, but finally the
card’s top speed was determined to be 175/160Mhz for the
core and memory clock respectively.
The core made it past
the Ultra’s default of 150Mhz, but the –7ns memory was
the limiting factor hitting only 160Mhz. Any other attempts,
even with 2Mhz increments was a big NO NO.
175/160Mhz… Compared with
the default for a typical non-Ultra board, that is a 40%
increase for the core and 7% for the memory. Not entirely
shabby! But I wished for better… (NB: your overclocking
success could vary for different batches of cards)
