The Asus V6600 is a great video card to
overclock. Asus supplied a tweaking utility to help you do just that. However,
it's not very good. The max the Asus tweak will let you overclock the V6600 is
142Mhz core and 195Mhz memory. Since the 5ns RAM is good for at least 200Mhz, I
know it can do more than that.
To overclock the V6600, I use Powerstrip by
EnTech (available at the download
page). Powerstip allows you to overclock the V6600 as high as 200Mhz core
and 250Mhz memory. After much fooling around with the setting, I found that max
the V6600 will run with the stock cooling system is 155Mhz core and 210Mhz
memory. I plan to put the Mellenger Video Card Cooling Kit on it soon and see
how much faster it will go.
Going from 120Mhz core to 155Mhz is quite a
jump. The GeForce 256 has a 480M pixels/second fill rate at stock speed. This
goes up to 620M pixels/second at 155Mhz. That puts the fillrate up to Voodoo 5
level. The increase fillrate and speed is reflected in the benchmarks

If the Asus V6600 running at stock speed is
fast, then it's just screaming when overclocked. Quake 2 runs so fast you can't
even hope to keep up.
One thing that troubles me is the speed
difference between 16 bit and 32 bit Quake 3. I setup the game using my own
custom setup which are:
Resolution: 1024 X 768
Graphic mode: CUSTOM
GL Driver: DEFAULT
GL extensions: ON
Full screen: ON
Lighting: LIGHTMAP
Geometric detail: HIGH
Texture detail: HIGH
Texture quality: 32 BIT
Texture Filter: BILINEAR
The game options are:
Marks on walls: NO
Ejecting brass: NO
Dynamic lighting: NO
Identify target: YES
High quality sky: YES

As you can see, the V6600 takes quite drop
when running Quake 3 at 32 bit. Mind you that 60fps is still damn good for
1024x768x32 bit color. Hopefully new drivers will be able to close this gap
between 16 bit and 32 bit Quake 3. Normally I run most games at 16 bits but
Quake 3 looks quite a bit better in 32 bit color.
