In iWave board definition files, the MT40A512M16HA-083E part is used because MT40A512M16LY-062E is not available as default in the Vivado dropdown menu.
Also, if custom part csv file is added then the output products go out of date every time the design is opened; this is a known issue on Windows PC. This is known issue while creating design using windows PC.
Therefore, as a workaround board file use MT40A512M16HA 083E DDR part, this part has same parameters as the DDR part on SOM but with 2400 speed bin.
