Thank you. A few weeks ago, I got a 2-way Xeon machine to test Intel X540 support. Afrer finishing X540 test, I noticed that the machine had DDR4. I tried to check the spdmem. It seemed that the machine's spdmem is not connecte via C612's internal i2c bus but via others. I stopped writing DDR4 support and just added the basic types only because I couldn't test with the machine. The machine was returned today.
I've just down-loaded the JEDEC Annex L document to get the DDR4 SPD specs. Once I get my machine back on the network I can look at adding full DDR4 support to spdmem.[ch] code. Give me a couple of weeks.
Also, if anyone out there has a machine with DDR4 memory and willing to test an update, please let me know!
