 The [CSCwd40071][68] defect affects versions 5.2(5c) and later with a fix available in 6.0(1g). However, the issue will only be triggered during Apic upgrades crossing 6.0(4c) due to [CSCwh80837][67].
 
 
+### N9K-C93180YC-FX3 Switch Memory
+
+This check applies to N9K-C93180YC-FX3 switches only. It checks whether the switch is using 16GB or 32GB of memory and flags switches running on 16GB memory. This check is not version dependent and runs for all upgrade versions.
+
+Impact: Running an N9K-C93180YC-FX3 switch with less than 32GB memory can lead to memory pressure and increase the risk of service instability.
+
+If any N9K-C93180YC-FX3 switch is flagged by this check, upgrade the switch memory to at least 32GB.

 ### Svccore Excessive Data Check
 
 Due to excessive `svccoreCtrlr` or `svccoreNode` managed objects, Apic gui stuck in loading multiple queries.
