Not quite, you need to set the frequency to 666Mhz, in turn that is 1333Mhz DDR.
For example, here you see the frequency at 450Mhz so that tells you that it is actually 900Mhz DDR.

On a side note : You have to manually adjust the timings and voltage for a stable system, you cannot just leave it on auto. I looked up your Ram and this is what you need to set to :
CL 7-7-7-20 (CAS-TRCD-TRP-TR) and then make sure that the voltage is at 1.8v
