First,in the Hardware Design,the description is "The intended range of operation is between 31 and 50 (0.905 V – 1.020 V), operation outside this range may impact device reliability or performance."

But in the newest Silicon Errata,the description is "Users are required to program their board CVDD supply initial value to 1.1V on the device."

What does this voltage difference mean?

Second,it is said that Fusion GUI will use the VID_CODE_RAIL command to poll the vid value.But I have checked  the SMBus log,there is no such command .
