 # PSRAM
 
+There seems to be a lot of "fake" chips, or maybe wrongly configured ESP32 Boards.
+
+
+For AP MEMORY, all "real" APS**64**04\*3SQR Chips should work. 
+
+For ESP PSRAM, all "real" PSRAM**64**\* should work
+
+64Mbit density = 8Mbyte PSRAM
+
+This Table is just a snapshot of chips which worked
