Dell PowerEdge XE8640 memory kit

This 1 TB kit contains eight 128 GB DDR5 RDIMM modules built for the Dell PowerEdge XE8640 rack server. It delivers registered ECC memory that matches the platform’s qualified specification.

Sustained load behaviour

Registered buffering and on-die ECC keep data integrity stable during continuous server workloads. The 1.1 V operating voltage helps limit thermal output while the modules run at the rated 4800 MT/s speed.

Deciding specification

The 4Rx4 rank organisation and CL40 latency define whether this kit fits the memory controller’s supported configuration. Verify the server’s qualified vendor list for 4Rx4 RDIMM support before ordering.

Questions sur cet article

How much power do the 1.1V 4800 MT/s modules draw under continuous server load?

Each 128GB stick runs at 1.10V DDR5 voltage; total draw depends on the XE8640 memory controller and workload, not on the modules alone.

What must the Dell PowerEdge XE8640 already have to accept this 8-module kit?

The server needs eight free 288-pin DDR5 RDIMM slots and a BIOS that supports 4Rx4 registered ECC modules at 4800 MT/s.

Can I mix these CL40 4Rx4 sticks with existing 2Rx4 or 2Rx8 modules in the same XE8640?

Dell's memory population rules for the XE8640 dictate which rank combinations are allowed per channel; check the server's technical guide before mixing.
