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.

At first glance the X1800XT looks a lot like an X850XT
