Hello Naveen,
You should use the "MemDownCh0Dimm0SpdPtr" to point to a buffer containing the SPD data and set MemDownEnable" to 1.

I don't see any relevant data member where we could define pointer to custom SPD settings or pass individual DIMMs configurations.
there is the memory-down option. It seems undocumented if that does more than switching from on-DIMM SPDs to SPD files. Maybe it's worth a try.
If that doesn't work out, you can always overwrite the SPDs on your DIMM's EEPROMs. Always keep a backup, though.
Hope that helps,
Nico
