Questions about Corsair Vengeance RGB Pro

The manufacturer number is not quite the same: CMW32GX4M2Z3200C16 and CMW32GX4M2C3200C16 (...Z3200C16 vs ...C3200C16). At the manufacturer's, the Z variant (this one) is titled "AMD Ryzen", also the AMD chipsets are listed in the compatibility. The C variant is listed in the KB from Corsair (3rd link). I own the C variant and run it with a Ryzen 7 3700X without any problems. Somewhere it also said that the products were compatible (otherwise I would not have procured the others). This one has smaller SPD latencies.
