*DIMM limit 1 – Max 64 GB LRDIMMs. No 128 GB, No AEP(Apache Pass).

**C indicates that the processor is continuously operating at the specified temperature or lower.

***E indicates the expanded operating temperature specified for the processor.

NOTE: Disabled ECM might reduce upper ambient temperature support on certain configurations.
