NEMIX RAM 128GB DDR5 6400MHz ECC RDIMM

This 128GB DDR5 registered DIMM runs at 6400MHz with CL52 latency and a 1.1V operating voltage. It is built for the Dell PowerEdge XE9685L rack server and uses 4Rx4 organisation with on-die ECC for data integrity. The module suits administrators who need maximum capacity per slot in a validated server platform.

288-pin DDR5 RDIMM installation notes

The stick follows the standard 288-pin DDR5 RDIMM form factor and seats in a compatible DIMM slot without tools. Because it is a registered 4Rx4 module, the platform memory controller must support that rank configuration; otherwise the system will not post. Mixing ranks or voltages across channels can also prevent boot, so populate slots according to the server manual.

Sustained-load behaviour in a Dell PowerEdge XE9685L

Registered buffering and on-die ECC keep signal integrity stable during continuous enterprise workloads such as virtualisation or database processing. The 1.1V supply limits power draw per module while the 6400MHz data rate maintains throughput over long periods. Thermal throttling is managed by the server’s airflow design rather than a module-mounted spreader.

Questions about this item

How can I verify the module is running at 6400MHz CL52 after installing it in my Dell PowerEdge XE9685L?

Enter the system BIOS or use a tool like CPU-Z to confirm the memory operates at 6400MHz with CAS latency 52 and 1.1V.

What is included in the package and do I need any extra parts for installation?

The box contains one 128GB 288-pin DDR5 ECC RDIMM. No additional components are required; the module installs directly into a compatible DIMM slot.

Which capacity and rank configuration should I choose for the PowerEdge XE9685L?

This part is a single 128GB 4Rx4 module (part number MR51200-744K1). Select it when you need one 128GB registered DIMM for that server.
