low speed GPIO for FMC?

Question asked by Tamas Novak on Dec 27, 2014
HAL_FMC_MspInit()  generated by F4 CubeMX   initializes all FMC related pins as
GPIO_InitStruct.Speed = GPIO_SPEED_LOW;
 
SDRAM is driven at max 84MHz frequency (STM32F429). I know that SPEED_LOW is only a slew rate (~a lower current generator at output driver), and traces to SDRAM are short and low capacitance, so they may be toggled quickly even with low driving power.

Isn't it a problem?  (It's a newly designed board; I haven't tested it yet)
