Dell PowerEdge XR7620 DDR5 ECC RDIMM

This NEMIX RAM module provides 16GB of DDR5 4800 registered ECC memory built for the Dell PowerEdge XR7620 rack server. It operates at 1.1V with CL40 latency and uses a 288-pin RDIMM form factor. The single-rank 1Rx8 design draws from major OEM DRAM chips.

IT teams expanding XR7620 capacity

Administrators adding memory to a Dell PowerEdge XR7620 will find this module validated for that platform. Buyers needing non-ECC memory, UDIMM form factors, or speeds other than DDR5 4800 should select a different part. Systems requiring a different voltage or pin count are not compatible.

Registered ECC with 1Rx8 organisation

The registered ECC design with 1Rx8 rank organisation is the specification that determines fit in the XR7620 memory subsystem. This combination enables the error correction and signal buffering the server platform expects. Mismatched rank or buffer type will prevent correct operation.

Questions about this item

What does the 4800 MHz rating mean for throughput inside the Dell PowerEdge XR7620?

The module runs at 4800 MT/s as PC5-38400; the server's memory controller determines the sustained bandwidth you will see in practice.

What does the PC5-38400 label tell me about the memory interface?

PC5-38400 identifies DDR5 at 4800 MT/s with ECC and registered signalling; the platform's controller sets the real-world ceiling.

Will the 288-pin registered DIMM fit the XR7620's memory slots without extra hardware?

Yes, it is a standard 288-pin DDR5 RDIMM designed for the Dell PowerEdge XR7620's registered DIMM sockets.
