Dell Precision 7920 Tower RAM Upgrade Guide
RAM Compatibility
The Dell Precision 7920 Tower requires DDR4-2933 ECC RDIMM memory modules. Registered DIMMs (RDIMMs) are required — unbuffered DIMMs (UDIMMs) will not work. With 24 memory slots, the maximum supported capacity is 1.5TB.
Important: Server and workstation memory must be ECC (Error Correcting Code) to ensure data integrity. Non-ECC desktop RAM will not be detected.
