Overclocking
6800GS
As noted earlier
in the review the 6800GS comes clocked at 425/500
which is a core clock which exceeds a reference ultra.
We all know though that manufacturers have been overclocking
the 6800U for a while to speeds in excess of 450mhz
so when beginning the overclocking test we had that
as an aim.
Using coolbits
we were able to overclock the card by a surprising
amount…
That’s
a 90mhz core overclock coupled with a near 60mhz overclock
on the memory !
X1600XT
There is only
one tool we could find which successfully overclock
the X1600XT and that was an internal ATI tool. With
every other utility we found that the memory wasn’t
detected correctly or the changes were not taking
effect…even ATI’s CCC didn’t recognise
the memory speed correctly we noticed.. So with a
starting speed of 590/697 we began our overclocking
of the X1600XT…
Our final stable
overclock ended up at an overclock of:
F.E.A.R. 1280x960 2aa 8af

The results
from overclocking show some reasonable increases on
the XT however the GS does benefit from a greater
increase in performance…whilst neither card
is completely smooth at this setting the GS does come
closest.
