Note: These results indicate that the performance decrement for slowing DRAM Speed from 50nS to 60nS or 70nS is minimal. When overclocking, the difference between 50nS and 70nS can be dramatic. The system might not boot at 50nS whereas this same system might run stable at 70nS. These results also compare the Symbios875 and Adaptec 2940UW controllers. The Adaptec controller has a distinct advantage. I compared these two cards previously in a similar configuration. For this earlier configuration there were no differences between the cards (Winbench97). Why is the Adaptec is faster in this configuration?. January 12, 1998.
