How to find the speed and CL settings of DDR3 SODIMM?
The RAM does appear to be counterfeit as far as I can see. 

I have that type of genuine Crucial memory (CT102464BF186D.C16FN) here - but it doesn't look like your picture.

The PCB is almost identical, but some markings on it are off. The number of components mounted at the top of the board are very much different. The actual DRAM IC on my memory has FPGA code C9BCM, which according to Micron is a 1.07 nsec rating - equalling a 1866 Mhz speed.

To top it off, the label looks very much the same - but instead of "Product of China", mine says "Assembled in USA". 

I can't say for sure that this means that it is counterfeit - it could be some kind of labelling/production error, or another revision of the same product or similar.
