I know that. What I said is the frequency table show that the 020 always use a 1/3 divider factor and now
increase the speed of the CPU and the RAM
by increasing the clock.
Sure, it's always possible to hack the divider to 1/2, but it's not interesting because the available range are close and the user will lose much memory speed and risk to permanently damage the CPU, using a wrong jumper setting.
But for the predicted ACA1232 Board, it may be interesting to switch it to 1/3 if it embed a 25Mhz certified CPU. Allowing to increase the RAM speed from 50MHz up to 80Mhz for a close frequency.
