This range, which is a _very_ safe setting, modern Hardware protects 
from overclocking anyway. I'd try manually specifying it, see man xorg.conf:

        HorizSync  horizsync-range
               gives the range(s) of horizontal  sync  frequencies 
supported  by  the  monitor.
               horizsync-range may be a comma separated list of either 
discrete values or ranges
               of values.  A range of values is two values separated by 
a dash.  By default  the
               values  are  in units of kHz.  They may be specified in 
MHz or Hz if MHz or Hz is
               added to the end of the line.  The data given here is 
used by the Xorg server  to
               determine  if  video  modes  are  within the 
specifications of the monitor.  This
               information should be available in the monitor's 
handbook.   If  this  entry  is
               omitted, a default range of 28-33kHz is used.
