Dell PowerEdge XR5610 Memory Kit

This 256 GB kit consists of two 128 GB DDR5 4800 ECC registered DIMMs built for the Dell PowerEdge XR5610 rack server. Each module runs at 1.1 V with CL40 latency and a 4Rx4 organisation across 288 pins.

Suited for administrators expanding XR5610 capacity

The kit fits Dell PowerEdge XR5610 systems that accept DDR5 4800 registered ECC memory in a two-module configuration. Buyers needing unbuffered DIMMs, non-ECC modules, a different pin count or a voltage other than 1.1 V should look elsewhere.

256 GB total capacity in a 2 x 128 GB registered

The decisive specification is the 256 GB capacity delivered as two 128 GB DDR5 4800 CL40 registered ECC DIMMs at 1.1 V. Confirm the XR5610 memory slot population rules before ordering.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the Dell PowerEdge XR5610 memory slots?

Yes, the kit uses the standard 288-pin DDR5 RDIMM form factor that matches the XR5610 DIMM sockets.

What is the correct order for installing the two 128GB modules in the XR5610?

Populate the channels identified in the server service manual first, typically one DIMM per channel, and ensure each module clicks fully into the ejector tabs.

How can I verify long-term reliability of the 4Rx4 ECC registered modules after deployment?

Enable ECC scrubbing in the BIOS and monitor corrected error counters via the iDRAC; a rising count on a specific DIMM signals it should be replaced.
