Assuming you have a dual channel motherboard, the latter 2 more or less agree. The actual clock speed is what CPUZ shows. But since you are running it in dual channel mode, the effective clock rate is 2 times 1463.7 or 2,927.4 which is very close to the BIOS reading of 2933.

The 3200 used in the advertising by Corsair is a theoretical number. You might get closer to that if your motherboard supports XMP or overclocking but you most likely won't notice any improvement because applications depend on a lot more than just RAM speed.

I have not a clue where Windows 10 gets its numbers.
