Cpu ID Wrong values?

My system specs

i3 2100 3.1GHz (Shows only 1.5-1.6GHz 16x on CPUID, figured its because of intels speed-step)
GA-H61M-S2V-B3(How do i check my BIOS version?)
4GB Kingston 1333MHz
2GB Corsair 1333MHz
Running win 7 64bit (Ultimate)

On CPU ID (ver 1.59) the max bandwidth for both the RAMS shows only 667MHz.

Is this because the PC is idling/ not doing RAM intensive tasks or something else?

Im not sure under which Category/sub- category this comes under.

    667MHz is correct. DDR has two accesses per clock cycle giving your system an effective memory clock of 1333MHz. The effective rate is how the RAM is marketed and the actual rate is what CPUID is reporting.
