Address Mirroring of command-address lines in memory down configuration (dual rank)

[Raj_Kr]

Hi,

We have used Intel Xeon Processor D-1746TER in our design and completed the schematic & layout design part.

We have connected 36 DDR4 (with ECC) devices on 2 channels in dual rank (x8) configuration.

In the reference document "576513_Idaville_LCC_PDG_Rev2_2"  page- 212, it is stated that "Address mirroring is allowed on second rank only for certain pins. SPD Bit 0 of Byte131
needs to be modified accordingly." 

Now we have a doubt related to this-

Which pins are allowed for address mirroring? we could not find any list of such address pins which can be address mirrored in Intel's reference design documents.

So, Please share us the details of those address pins.\

Please try to answer asap.

Thank You 

Raj Kumar
