Well obviously the stock cooler isn’t going to do much at breaking
3D Mark records.
So we put on our home-built -90C cooler on the
card and pushed her all the way to 656Mhz core, from the default
Thats a very impressive clock speed! But what’s a real record
without running it in SLI mode?
As we have only 1 XFX 6800 Ultra, we ran it together
with the Asus 6800 Ultra in SLI configuration and took home
the top spots at FutureMark 3D Mark 2005 and 2003:
Here is the details of the configuration:
- XFX 6800U + ASUS 6800U SLI @ 614/1404
– FX55 @ 13 x 266 -> 3464Mhz
- DFI NF4 Ultra modded to SLI
- Kingston Hyper X BH5
- SilverStone 650w Power Supply
The CPU runs at -94C, GPU1 runs at -55C
and GPU2 runs at -91C.
Here is a picture of the extreme setup:
Well I must say that I am pretty impressed with how well the XFX
6800 Ultra has overclocked for me. With the right amount of cooling,
it just scaled higher and higher!
