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.

Make sure the ram voltage is being set according to spec.

I inspect the spec for RAMs in BIOS and it requires 1.65v while the current v is about 1.5. I will provide some photos for u to get it easier...

The SPD tab in cpu-z will tell you all the timings and the voltage needed for the xmp profile, setting xmp profile in the bios should set all the timings right, you might have to manually set the voltage, check the timings just to be sure they are at the right settings.

yeah just manually set the timings voltages and speed in your bios so that it matches the rated xmp 1600 profile. i had an issue with my board not properly set my qpi voltage to correlate with the dram voltage so it would bsod when i overclocked. so i just manually set everything and even squeezed out a little better timings than the rated xmp profile.

Thank for your support, when enabling the XMP function, the BIOS automatically sets it all for me that match the producer's parameter so I don't have to do anything at all. It turns out that one stick of Rams cause the issue, the seller change new one for me and the same situation occur. The slightly difference is it takes longer to trigger the issue :( 

Now, I intend to change the mobo to asrock FM2+-A55-HD+ with the same Kit of Ram from another store. We'll know if it work well on Monday, but now I myself conclude that the combination between MSI mobo and this Ram kit are some kind of bad idea...
