To do proper turbo nowadays, you need to use hpgcc. The clock changing procedure was completely reimplemented in hpgcc and hpgcc3 to make it safe to use. It adjusts CPU clock, but also the memory clock is adjusted to keep the memory working at the same original speed, so it doesn't crash. If somebody were to improve Al's tools by looking at how hpgcc corrects the memory timings, it could be made to work consistently on all models. However, I'm not sure this qualifies as overclocking. The ARM chip in the 49 series has selectable clock up to 200 MHz, so we are never exceeding any design parameters. So this is one of the cases where "Turbo" is not the same as overclocking. Claudio |
