Refresh Rate Problem

[Ahmed Abdel-Aliem <me2resh gmail com>]

How Can i Change the refresh rate of the monitor
i use fedora core 3
my screen resolution is 1280 X 1024
when i go to Applications --> Preferences --> Screen Resolution
i find that there is only one value for the refresh rate which is 60
Hz & i can't change it
i went to the file /etc/x11/xorg.conf
i found this section :

Section "Monitor"
	Identifier   "Monitor0"
	VendorName   "Monitor Vendor"
	ModelName    "710E"
	DisplaySize  330	250
	HorizSync    30.0 - 71.0
	VertRefresh  50.0 - 160.0
	Option	    "dpms"
EndSection

what should i do to increase the refresh rate of my monitor from 60 Hz
to 90 Hz or 100 Hz ??

can anyone help me with this please ?
