IMX6 DDR Stress Test affected by ARM Core Clock Changes

Using the IMX6D and running the DDR Stress Test and getting failures (one byte with incorrect data) when the ARM Core Clock set to 996MHz. Changing the ARM Core Clock to 792MHz results in DDR Stress Tests passing. How does changing the ARM Core Clock (PLL1) affect the DDR Stress Test? The DDR clock is set by PLL2.
