System-specific DDR5 kit for Dell PowerEdge XE8640

This NEMIX RAM kit supplies 256 GB of DDR5 4800 memory in eight 32 GB modules. It is built for IT professionals who maintain Dell PowerEdge XE8640 rack servers and need validated, registered ECC capacity.

Registered ECC RDIMM with 2Rx8 organisation

Each module is a 288-pin DDR5 RDIMM running at 1.1 V with CL40 latency. The registered buffer and on-die ECC protect data integrity for mission-critical workloads on the qualified platform.

Eight-module population for maximum capacity

The kit fills eight DIMM slots with identical 2Rx8 modules, freeing the administrator from mixing part numbers. It requires a Dell PowerEdge XE8640 motherboard that supports DDR5 4800 registered memory; systems needing unbuffered DIMMs or a different pin count cannot use this kit.
