As you can see, it´s all correct and the clock rates are 470/1300 MHz, as promised. However when we tested the reference card we noticed that RivaTuner tool (by A. Nikolaychuk aka Unwinder) indicated some other clock rate that was about 40MHz higher than nominal (430MHz reference + 40MHz = 470MHz). The matter is that at that time Rivatuner determined the maximal clocking value.
Together with the developer of this utility we started to investigate the matter testing the card with ±5MHz steps and dumping register reports. We found out there were THREE clock rates at once! Now there´s information in the Web that NVIDIA privately mentions more clock rate values as the GPU itself consists of multiple unit, each of which is able to work at its own clock rate.
