I am currently running a 1.6A and it will go to 170FSB @ 1.65 volts rock stable. I have also run it at 155FSB with the dipswitch trick enabling 3:4 ratio and everything works great. If I try to use the dip switch trick and raise the FSB over 155 it refuses to post. In 1:1 the FSB goes to 171 stable. I have tried lots of different types of ram including Corsair PC3200 and Twinmos PC3200. Is there a secret to getting it to run 3:4 over 155? I think I tried to set the speed withj the dipswitches but it still wont work. Any ideas? Thanks in advance.
