Probably not, most DDR3 RAM is 1333 MHz (you double the 667MHz reading you have). G. Skill says your RAM will run successfully at 1600MHz, but you will likely have to make manual adjustments in the BIOS to exceed the default 1333MHz.
To achieve higher speed, e.g. 1600MHz, you use either the RAM's XMP profile if it is available in your motherboard's BIOS settings, or you manually set the speed, voltage, and latencies in your BIOS, using the settings on the RAM's labels.
agree with the words of @ treefrog, if you want higher with 1600 RAM and you have to do manually Oc via Bios.
please note that the AM3 mobo to default only Ram 1333 and 1600 will be written if the OC or 1600 (OC), even if you have the RAM 2000 will still be legible 1333 (667) if you do not change it manually in bios
