yes, now you told me I see it's actually in the logs:

(--) MACH64(0): Reference clock 157.5/11 (14.318) MHz.
(II) MACH64(0): If modes do not work on Ultra 5/10 or Blade 100/150,
	set option "reference_clock" to "28.636 MHz" or "29.5 MHz"

by using either 28.636 or 29.5 I now get no "signal over range".
In fact I just get a black screen. Not sure if this is worse or better...

many thanks
