Check out your /etc/X11/XF86Config file. There should be a Monitor section in there where you can define the frequencies.

Look into your monitor's manual first. In the tech data you should have correct values for your monitor. I think your horiz sync is probably even higher than you have now.

If this doesn't work, run xvidtune. It's a program for tuning settings for resolutions - the result you get should be inserted into the config as a modline. Can write more about it if you decide to use this way.
