B.3 Intel® DDR5 DIMM Support Disclaimer
Intel DDR5 DIMM Support Disclaimer
Intel validates and only supports system configurations where all installed DDR5 DIMMs have matching
“Identical” or “Like” attributes (see following table). A system configured concurrently with DDR5 DIMMs
from different vendors are supported by Intel if all other DDR5 “Like” DIMM attributes match.
Intel does not perform system validation testing. Intel does not support system configurations where all
populated DDR5 DIMMs do not have matching “Like” DIMM attributes as listed in the following table.
Intel only supports Intel server systems configured with DDR5 DIMMs that have been validated by Intel
and are listed on Intel’s Tested Memory list for the given Intel server product family.
Intel configures and ships pre-integrated L9 server systems. All DDR5 DIMMs in a given L9 server system
as shipped by Intel are identical. All installed DIMMs have matching attributes as the attributes listed in the
“Identical” DDR5 DIMM Attributes column in the following table.
When purchasing more than one integrated L9 server system with the same configuration from Intel, Intel
reserves the right to use “Like” DIMMs between server systems. At a minimum, “Like” DIMMS have
matching DIMM attributes as listed in the following table. However, the DIMM model #, revision #, or
vendor may be different.
For warranty replacement, Intel makes every effort to ship back an exact match to the one returned.
However, Intel may ship back a validated “Like” DIMM. A “Like” DIMM may be from the same vendor but
may not be the same revision # or model #, or it may be an Intel validated DIMM from a different vendor.
At a minimum, all “Like” DIMMs shipped from Intel match attributes of the original part according to the
definition of “Like” DIMMs in the following table.
Table 14. DDR5 DIMM Attributes Table for “Identical” and “Like” DIMMs
• DDR5 DIMMs are considered “Identical” when ALL listed attributes between the DIMMs match
• Two or more DDR5 DIMMs are considered “Like” DIMMs when all attributes minus the Vendor, and/or
DIMM Part # and/or DIMM Revision#, are the same.
