The limited edition Sapphire Radeon X800GTO² is worth searching out if you
like overclocking your graphics card - and at the time of writing, Sapphire had
just confirmed it would be
making more
than originally planned.
Despite the X800 in the name, the X800GTO² uses the R480 core found in the
X850XT, not the usual R430 core. This is because only 12 of the 16 pixel
pipelines work straight out of the box, hence the X800 label.
But with a Bios tweak (available on the web) you can enable the remaining
four pipelines. Not only that, but with the standard cooling you can also
overclock this board up to an X850XT and further.
Some have managed to get cards running faster than X850XT Platinum Editions,
but the one we had couldn’t quite manage this.
