- Published maxima are platform- and configuration-dependent; confirm the applicable manufacturer documentation before building or servicing a system.
Service and archival notes
Record the physical CPU marking, OPN and stepping; host motherboard and revision; firmware; populated DIMMs; cooling; and test conditions. Treat measured behavior as distinct from the published specification.
Do not apply package torque, voltage, memory population or cooler guidance from another Threadripper generation or socket.
