Can we use W634GU6NB-11 (Winbond Speed grade 1866) with STM32MP1ADD3 ?

Hi,

Can we use a DDR3L from Winbond with part number W634GU6NB-11 (Speed bin 1866) with STMPU STM32MP1ADD3.

As STM32MP1 datasheet suggest that it can support up-to 1066. So using above part from Winbond will have any interface issue ?

Thanks.

Hi @PS.2

Faster memory could work at slower frequency.

Will likely work with default DDR3L-1066 conservative settings. Please look at AN5168 for details of configuration choices which could probably enhance a bit the performances (CL improvement gain is usually barely noticeable at system level, especially on x32 DDR).
