    Try a different diagnostic such as CPU-Z, it's free.
    CPU-Z | Softwares | CPUID
    If the computer is still under warranty check your bill of sale then contact the seller. If you got the wrong product not much can be done here to help.

    What is displayed under BIOS?

    Is your BIOS up to date?

    Run CPU-Z or HWinfo. What does it finds?

    What else are you using to verify that? Does a turbo-type function exist with the CPU or motherboard? As long as I've been working with computers [first one in '92, worked in a shop building them in '94] and as good as Windows usually is I've never seen it always having all functions as 100% correct. I'm not arguing the point but to quote from someone, trust but verify.

    The 6400 and 6500 appear to be nearly identical, except the 6400 has a clock multiplier of 27X, and the 6500, 32X.

    Intel(R) Core™ i5-6400 Processor (6M Cache, up to 3.30 GHz) Product Specifications

    Intel(R) Core™ i5-6500 Processor (6M Cache, up to 3.60 GHz) Product Specifications

    However, the 3.27GHz shown is within the boost clock range of the 6400. I wonder what ferquency would be present if the CPU was idling?

    I'm not prepared to bet that Windows is mis-reporting the CPU.
