The Club3D X1800XT is based on the ATI 109-A52031-20 PCB with
redesigned power supply circuits for better stability. Compared to the previous
109-A52031-10 PCB, it means that if the card is flashed with a new BIOS, it
would allow higher voltages which would allow high clock frequencies. However,
when this information arrived at our labs, it was a little too late to test
the card as the card had already been returned.
