The fact that 3960x officially supports up to 3200Mhz then I cannot see how OC RAM at 3600Mhz can be fully optimized for TRX40. I very much doubt there is an XMP profile or similar that will work at 3600Mhz
It is the IMC on the chip that will determine the rated frequency achieved.
If you are deciding what will run on your system then refer to your MB QVL and select a single kit the frequency your MB and CPU support that are known to work and have been tested. Don't rely on what Corsair have to say.
