Bug ID 32927658 - Memory population rule incorrectly mentioned
In the Oracle Exadata Storage Server X8-2 EF, HC, and XT Service Manual (E93395-06) that was published on the Oracle Documentation web site, the document provides incorrect information in the DIMM Population Rules section.
"If your memory configuration supports DCPMM DIMMs and DDR4 DIMMs, populate each processor socket with six 128 GB DCPMM DIMMs and six 16 GB DDR4 DIMMs. Populate DCPMM DIMMs in each black DIMM slot (channel slot 0) and populate DDR4 DIMMs in each white DIMM slot (channel slot 1)."
The correct information is as follows:
Populate DCPMM DIMMs in each White DIMM slot (channel slot 1) and populate DDR4 DIMMs in each black DIMM slot (channel slot 0).

DIMM Population Rules
-
The server supports 64-GB quad-rank (QR) Load-Reduced DIMMs (LRDIMMs), 32-GB dual-rank (DR) Registered DIMMs (RDIMMs), and 16-GB DR/SR RDIMMs.
-
Mixing 32-GB dual-rank DR 2Rx4 RDIMMs and 16-GB single-rank 1Rx4 SR RDIMMs in a server where the system is configured with a mix of both on every channel is supported.
-
Randomly mixing 32-GB dual-rank DR RDIMMs and 16-GB single-rank SR RDIMMs on channels can result in very low memory performance and is not supported.
