Windows 7: How do I calculate the speed my ram is running at?

How do I calculate the speed my ram is running at?

Alright, so I installed CPU-Z and I'm unsure to know what my ram is actually being clocked at. It shows that the DRAM Frequency is 933.4 MHz which should equal up to about 1866 MHz which is what the ram is defaulted to, but then when I go over to the SPD section it shows the max bandwidth is at 667 MHz.

So what does each one mean, what is my ram being ran at?

That is perfectly normal. Mine is reading the same. I think that it could be a bug in CPU-Z or, more likely, that it only picks up the fastest JEDEC timings for the Max Bandwidth section. You are, however, running at the higher frequency which is the XMP profile settings.
