Ok good. I figured it was wrong SPD values but didn't look too closely to see if the values you had matched the DDR you were using. I had a spreadsheet SPD generator somewhere around here that would give the correct values based on the DDR datasheet.

Yes, After changing the SPD values of DDR4, Its start working fine.
Thanks

Greetings .
We are working on intel c508 intel denverton board . It has a soldered 4GB DDR4 connected to Channel 0 , Dimm 0 .
Below are the changes made :
1. We are using harcuvar board as a reference . I have selected * Enable Memory down option in menu config
2. Added spd values file in src/mainboard/intel/harcuvar/spd/spd_filename.hex
3. spd.bnhttps://linkprotect.cudasvc.com/url?a=https%3a%2f%2fspd.bn&c=E,1,7tAVCngs6GE7koEGV9DQzNl4vdXT79vTNaF5bAfY8mqX1XlOeIpXjJMLE0oHY49o6WrWC3gS-8FphRJHeaqt7Qo4RtXkTyXg8-YErgGfY8zY0QslM_s99PZn&typo=1&ancr_add=1 getting generated in CBFS
