  • Hi - is there some way to add extra clock selection speed via firmware update or is it hardwired at 7,14,21,28 and 42MHz full blast?

    I would like to select 35MHz. I am getting glitching on some games at 42MHz, but the speed it needed, so therefore I would like to try 35MHz.:thumbup::thumbup:

    cheers

  • The CPU clock must be a result of a whole-number division of the base frequency, which is 85.12548MHz. You can't get to 35MHz with a whole-number division.


    If the computer crashes at top speed, you might want to try a better power supply - such as the CA-PSU.

  • ok cheers -I have a Meanwell RT50b new PSU fitted. it does not crash. Indianapolis 500 glitches on high graphics level at 42MHz sadly. 1mb chip ram installed too. 28MHz fine - I just wanted to push a bit more :) Appreciate the quick reply
