I am using DDR3L in the Arria® 10 EMIF with an operating frequency of 533.333MHz, should I select -1066 for the Speed Bin setting on the Mem Timing tab in the IP parameter settings, the rate corresponding to the operating frequency?

The Speed Bin setting on the Mem Timing tab of the EMIF GUI should be set to the Speed Grade (maximum supported rate) of the DDR3L component to be used, not the operating frequency.

For example, if you are connecting a -1600 or -2133 component, use that value.
