Msi GT628 DDR3 Ram?

I have a GT628 with a P8700 proc and what should be DDR3 Ram at 1066 Mhz. However both CPUz and another application, Speccy from Piriform show this:

Why only 400 Mhz. Somebody said that because it's dual channel it's actually 2x400, but that still isn't 1066 Mhz. Should i be worried?

Check your bios, it might have an option to change the frequency.

MSI might have set the frequency lower to allow headroom for overclocking with the turbo button.
