Is my RAM running at the advertised speed?

Just built a new computer and I wanted to make sure my RAM is running at the speeds advertised. I turned on the XMP profile inside the ASUS VIII Extreme bios and I loaded up CPU-Z to see if they're running as advertised. But, I'm a novice, and don't fully understand what I'm looking at. Was hoping you guys could clear it up for me and make sure it's running at the speeds it should be.

My ram is G.SKILL TridentZ Series 32GB (4 x 8GB) 288-Pin DDR4 SDRAM DDR4 3400 (PC4 27200)..

And here is a picture of the Memory and SPD tabs in CPU-Z..

The memory is listed as 3400Mhz, but under the SPD tab it reads "Max Bandwidth: DDR4-2132 (1066 MHz)" So does that mean it's running at 2132MHz rather than 3400?
 
Solution
Yes, your RAM is running at its advertised speed/timings. Just look at the Timings info on the Memory tab on CPUz. They line up with the advertised values (1700 MHz DRAM frequency corresponds to an advertised speed of 3400 MHz, because DDR is double data rate).
