Dell PowerEdge XE9640 Memory Kit

This 128GB kit contains four 32GB DDR5 4800 registered ECC RDIMMs built for the Dell PowerEdge XE9640 rack server. Each module runs at 1.1V with CL40 latency and a 2Rx8 organisation. The 288-pin form factor matches the server's memory slots exactly.

Suited for capacity upgrades on the named Dell

Administrators expanding memory in a Dell PowerEdge XE9640 will find the correct speed, voltage and registration here. Buyers who need unbuffered UDIMMs, non-ECC modules or a different pin count should look elsewhere because this kit is registered ECC RDIMM only.

Registered ECC RDIMM with 2Rx8 organisation

The registered buffer and on-die ECC protect data integrity under sustained server workloads. The 2Rx8 rank structure determines how the memory controller addresses each 32GB module. Confirm the platform requires registered ECC RDIMMs before purchasing.
