I have 2x2gb ddr3 1600 memory module. It shows only 1333 in bios and cpuz. When i enable AMP nothing is changed in frequency. But when i manually set the frequency at 1600 then pc rebooted and consistant beeping sound and then reboot to bios and ask to set default value. So whats the problem. Plz help.
