@Gordon yes, my 60-second test was off by a factor of 84/16, ie, 5.25.
Interestingly my F401 board has just the black crystal (which is a 32k
clock crystal - so not the high speed oscillator).
The C-01 version of the motherboard has neither X2 or X3, the C-02 version has X2. You got yours directly from STM, so they sent you the latest version I guess. I got mine from Mouser just last week and it was C-01 so I guess they dumped old stock on me :(
