Do you have experience of using external RAM with WIFI and sd card.
SD card read 32k block some time fails when external RAM is enabled.
SD card is FAT 32.
WIFI mem fail as well when reading SD card in SPI mode. I am not using 4bit mode.

Re: External RAM with WIFI and SD card.
Strange; how exactly does it fail? What hardware do you use? Do you have some (simplified if possible) code that illustrates this behaviour? Are you sure your power supply is good enough, perhaps the 3.3V rail is sagging while you do these things?
