Dell PowerEdge XR7620 upgrade kit

This 256 GB kit provides two 128 GB DDR5 4800 registered ECC modules built for the Dell PowerEdge XR7620 rack server. Each module uses a 288-pin RDIMM form factor with a 4Rx4 organisation and operates at 1.1 V. The memory is designed for IT teams who need to expand capacity in this specific platform.

Two matched 128 GB modules

The kit ships as a matched pair so the server can populate two slots with identical 4Rx4 registered DIMMs. This arrangement lets the memory controller address the full 256 GB without mixing ranks or speeds. No heat spreaders are included, relying on the chassis airflow of the XR7620 for cooling.

DDR5 4800 registered ECC limits

Registered ECC DDR5 at 4800 MT/s adds a clock cycle of buffering and error correction that increases latency compared with unbuffered memory. The 4Rx4 density also restricts the maximum number of ranks per channel the platform can support. Systems that require higher frequencies or lower CAS latency cannot use this kit.

Spurningar um þessa vöru

Will the 288-pin DDR5 RDIMM modules need any firmware updates or thermal pad replacements over time?

No firmware updates or thermal pad replacements are required; the modules have no heat spreader and operate at the standard 1.1 V DDR5 voltage for the life of the system.

What is the first limit reached when the 4Rx4 registered ECC modules run at 4800 MT/s continuously?

The CAS latency of CL40 sets the timing boundary; sustained throughput cannot exceed the PC5-38400 data rate defined by the 4800 MT/s speed rating.

How much heat and power do the two 128 GB sticks draw when the Dell PowerEdge XR7620 runs all day?

Each module runs at 1.10 V without a heat spreader, so total power draw stays at the DDR5 1.1 V specification and thermal output remains within normal server DIMM limits.
