DM6446 - SDTIM0 and SDTIM1 register settings

I'm using the 810-MHz DM6446 chip which supports a 32-Bit DDR2 SDRAM Memory Controller up to 189-MHz. I've measured the DDR_CLK on PIN W7 and verified we are running a 189-MHz clock. The SDTIM0 and SDTIM1 registers for the DM6446 are calculated using the DDR_CLK. Through some research I found the SDTIM# registers are set in U-Boot but the values that are being set are were calculated to be 162-MHz.

What effects would having the SDTIM registers set to a value calculated for 162-MHz while running a 189-MHz clock?

I'm including the current calculated values and what I believe the calculated values for the SDTIM registers if they had been calculated with a 189-MHz clock.

Can someone please verify my calculations are correct?
