DDR4 RAM Modules identification

[Peterads]

Hi, i recently bought a used set of Kingston HyperX Fury 32GB (4 x 8GB) DDR4 2666 MHz RAM HX426C15FBK4/32 and have run Memtest86 to test it. SPD detected it as 4 sticks of KHX2133C14D4/8G.
Could this be a glitch or have i bought possible counterfeit goods?

The SPD info is read directly off of the RAM sticks. You can verify the SPD info by using RAMMon or other 3rd party memory info tools.

Here is the specs sheet for HX426C15FBK4/32. There doesn't seem to be one for KHX2133C14D4/8G, however, you can possibly compare the timings see if the RAM sticks meet the specs for HX426C15FBK4/32.
