Table 7-2 shows External Memory Interface Performance in Stratix® V Devices. It states that the soft controller can support 933MHz DDR3 SDRAM with 1.35V (DDR3L). This statement is incorrect. The maximum performance for DDR3L is 800MHz . You can find more information about DDR3 performance from External Memory Interface Spec Estimator.
