1) Don't use the Gigabyte EazyTune software, it sux. Make the changes in your BIOS.
2) Set your FSB:RAM ration to 1:1.
3) Increase your CPU and RAM voltages by 0.1v. Make sure to disable any power saving technologies and what not that you aren't going to use.
4) Increase your FSB 10MHz at a time
5) Make sure to manually set your RAM timings, since if you lower the ratio your board my try to shorten the timings thinking that the RAM is going to run at a lower speed. If the board won't boot at those timings it should give you an error beep and then boot up at stock settings. If it does that try putting in longer timings and raise voltages if needed. Don't raise the voltages too far though or you'll break something

6) Boot up and run Prime 95. Also download Everset or some other utility to monitor your Temps. If none of the threads fail after 3 itterations and none of your temperatures are dangerously high then reboot.
7) Reboot, go back to step 4 as necessary
