Question about using Pocket Hack Master to overclock...

[lgmcben]

I've iPAQ h1910(PXA255 200MHz). When I tried to overclock the device to 398/118(I'm not sure, can't remember the exact number T_T), the program prompt me If i'm sure to do this. It said stuff like if my SD ram not support 1/2 mem clock then it may be dangerous to do this. Can anyone confirm that h1910 can be overclocked to 398 or 472 MHz?
Thank you very much. ^_^

It's faster you if overclock it to 300/150 than 400/100. The increase in bus speed has a much greater effect than an increase in CPU speed as even at 200MHz the bus speed is a bottleneck. But no, the 200MHz CPU is incapable of a 200% overclock.
