I got the base Mac Pro (Quad core, D300, 12GB) Planning on upgrading the cpu down the line, my question is regarding memory.

I upgraded to Corsair Vengence 32GB (4x8gb) 1866mhz. When I click on the About my mac it shows the memory is only 1333mhz.

Do I have a faulty memory stick?

OS 10.11.1

My guess would be the system can only run your RAM at CL9 (1333MHz), because the nMP can only run at 1866MHz with CL13, but not CL10 (your RAM's spec).
