refresh rate on 5970 limited to 60Hz

Even with Catalyst 10.9 it seems to be impossible to set the refresh rate of analog monitor higher than 60Hz.

This is a very annoying bug as it gives me headaches.

I checked the xorg.conf and manually added a refresh rate setting, but this didn't help. Please find attached my xorg.conf for IGP (5970 has the same issue).

Catalyst Center won't let me choose any refresh rate other than 60 for my analog Monitor.

What's the problem?
How to solve it?

AMD Phenom II X4 905e

GFX1: AMD Radeon 5970
