Underclocked ram?

[chilypepper]

Hi, i just finished my new rig with 8gb of dual channel Corsair Vengeance memory @ 1600Mhz on a Gigabyte GA-990XA-ud3 Motherboard.

I installed CPUID and found out that my ram isn't running at 1600 but 1333. Also I noticed in the top right it says unganged, shouldn't it say ganged since it's dual hcannel? Heres a sceenshot

In general you should be running in unganged mode for the best performance. It gives you the flexibility of two 64-bit channels vs. one 128-bit channel.
