I can't manage to get Crash Bash to boot properly, it freezes with a sound at the "Sony Computer Entertainment America Presents" screen, right after the playstation logo screen.

I'm overclocked @ 750MHz, with titans kernel and slightly modified ulv settings..

Don't understand how so many people can do it but I can't. :P

I've tried various multipliers, x2, x4, x5, x6, x1..

Any thoughts or ideas would be great. thanks
