What is this?
I see in code, you are adding DIMM specific parameter to support new frequency.
Is this code changes because you are adding a different DIMM or adding support for new frequency?
If new DIMM, What if someone tried to use the frequency "2133" with the original dim on board.

Please provide more details in description.

Thanks
Priyanka
