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.

Questions about this item

How does 4800 MT/s DDR5 perform once installed in a Dell PowerEdge XE8640?

The kit runs at 4800 MT/s with CL40 latency and 1.1 V, delivering the rated PC5-38400 bandwidth for registered server workloads.

What does the 288-pin RDIMM interface cap in practice?

The 288-pin DDR5 RDIMM form factor supports ECC and registered operation at the module's rated 4800 MT/s within the server's memory controller limits.

Will the 2Rx8 32 GB modules physically fit the XE8640's DIMM slots?

Yes, each 288-pin RDIMM matches the XE8640's DDR5 slot keying and the 2Rx8 layout is validated for the platform's memory channels.
