Server Memory Kit for Dell PowerEdge XR11

This 384GB kit contains six 64GB DDR4 3200MHz ECC Registered RDIMM modules designed for the Dell PowerEdge XR11 rack server. It provides high-capacity memory for virtualization, databases and enterprise workloads. Each module uses 2Rx4 organization with a CAS latency of CL22. The kit is built with major OEM DRAM chips for stable operation.

Thermals and Power in Normal Use

The modules operate at a standard 1.20V DDR4 voltage without heat spreaders. Registered buffering reduces electrical load on the server memory controller during continuous operation. ECC functionality detects and corrects single-bit errors to maintain data integrity under sustained workloads. The design supports reliable performance in dense server configurations.

What the Bundled Kit Changes

The six-module kit populates multiple memory channels to maximize bandwidth for the Dell PowerEdge XR11 platform. Factory-matched modules eliminate timing mismatches that can cause instability in large-capacity configurations. RIMLANCE quality assurance testing validates compatibility before shipment. Lifetime replacement warranty and technical support are included with the kit.

Questions about this item

How do I install the 288-pin DDR4 RDIMM modules in my Dell PowerEdge XR11, and which step is most often missed?

Power down the server and disconnect power cords, then open the chassis. Align each 288-pin module with the slot key and press firmly until both retention clips click. The step most often missed is confirming every clip has fully engaged on both sides.

What maintenance or replacement will this 384 GB ECC Registered kit need during its service life?

No scheduled maintenance is required for the modules themselves. Keep the server’s air filters clean and verify ECC error logs periodically; replace any module only if the system reports persistent correctable or uncorrectable errors.

What limit appears first when the 64 GB 2Rx4 modules run sustained workloads at 3200 MHz?

The thermal limit of the unbuffered DRAM packages without a heat spreader is reached first; adequate chassis airflow must keep module temperatures within the DDR4 1.20 V operating envelope.
