To overclock the Asus 6800, I used Powerstrip
by EnTech (available at the
download page). Powerstrip allows you to overclock the 6800 as high as
200Mhz core and 400Mhz memory. To help keep the card cool, I added a new Global
Win card cooler to the Asus V6800.
Global Win Card Cooler
The Global Win card cooler is made up of two YS Tech fans.
Together they blow over 50 cubic feet of air per minute over the video card.
With the help of the Global Win card cooler, I was able to overclock the V6800
to 155Mhz core and 350Mhz memory. I'm sure I can get higher if I were to add a
Mellenger
Video Card Cooling Kit to it. Adding a cooling kit would be very easy to do.
Asus video cards seem made for overclocking. The factory heatsink is not glued
to the video chip. Removing the heatsink is as simple as pushing out 2 clips.

Overclocking the V6800 doesn't give much
perfomance increase at lower resolutions, but it really helps a lot when the
resolutions starts reaching for the stars. Quake 3 is completely payable at
1600x1200 resolution! While I didn't have a UT timedemo, I found UT would run
flawlessly at 1600x1200x32 bit color. The frame counter rarely went below
50fps.

Overclocking the V6800 really helps when
going to super high resolution and 32 bit color. At stock speed, Quake 3 wasn't
that great at 1600x1200. However, with card running at 155/350, it's not too
bad.
