IBM eServer OpenPower 710 Technical Overview and Introduction
2.3.1 Memory placement rules
The memory features available at the time of writing for the OpenPower 710 server are listed
in “Memory features” on page 5.
Memory DIMMs must be ordered and installed in pairs. Memory feature numbers may be
mixed within a system. The DIMMs slots are accessed by first removing the PCI riser book.
Memory is installed in the following order: J2A and J0A, J2C and J0C, J2B and J0B, and J2D
and J0D. Memory must be balanced across the DIMM slots. The Service Information label,
located on the top cover of the system, provides memory DIMMs slot location information.

2.3.2 Memory restriction
OEM memory is not supported by IBM on the OpenPower 710 server. OEM memory is not
certified by IBM for the use in OpenPower servers. If the OpenPower 710 server is populated
with OEM memory, you could experience unexpected and unpredictable behavior, especially
when the system is using Micro-Partitioning technology.
All IBM memory is identified by an IBM logo and a white label printed with a barcode and an
alphanumeric string, illustrated in Figure 2-5.
