Enabling XMP causes system freeze...

Hi everyone, I built this CPU last week:

CPU: AMD Richland A6-6400K Black Edition 3.9GHz
Main: MSI FM2 A55M-E33
Ram: Corsair Dominator 4GB ( 2x2GB ) DDR3 bus 1600 cas 7
PSU: Cooler Master Elite Power 350W
HDD: Western Digital Caviar Blue 250GB
Case: HiGamer D052 Red USB 3.0

After setuping everything, I realize the Ram operates at bus 1333MHz so I go to BIOS and eable the XMP function. The RAMs now operate at 1600MHz after I reboot the system so I start using the PC normally. Now the problem occurs, when I surf the Internet for about 10 minutes the system suddenly freeze without any warning. I can't move the cursor, the keyboard is useless so I hvae to hard reset the system.

I disable the XMP and the problem disappears . Then I try to manual adjust the bus by chosing the 1600MHz option, the problem comes back !

Hence, I want to ask if there is any way to make those RAMs operate stably at 1600MHz or not. Both Ram and Mobo of my system support XMP so if the system operates at 1333Hz it's a waste of money.

Please help my with this. Thanks.

You could check for a BIOS update to remedy that.
It may be a matter of RAM compatibility, so an update may help.
Usually after newer versions are published the compatibility lists for both ram and cpus grow.
