128 GB DDR5 ECC RDIMM Kit for Dell PowerEdge XR7620

This 128 GB kit contains four 32 GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It is built for IT teams upgrading a Dell PowerEdge XR7620 rack server to meet memory-intensive workloads. Modules operate at 1.1 V and use 288-pin DDR5 RDIMM form factor. The kit is validated for the XR7620 platform.

Sustained load behaviour with registered ECC DDR5

Registered buffering and on-die ECC keep data integrity stable during continuous server workloads such as virtualisation, database caching or high-throughput networking. The 1.1 V operating voltage helps limit thermal output when all four slots are populated at rated speed. CL40 timing is the standard JEDEC value for DDR5 4800 registered modules under prolonged use.

DDR5 4800 interface limits in a four-DIMM

Running four ranks per channel at 4800 MT/s reaches the electrical limit of the DDR5 4800 standard without downclocking. Population rules for the XR7620 may restrict maximum speed when all channels are fully loaded; the platform firmware governs the final operating frequency. No higher DDR5 speed grade is supported by this module specification.

Questions sur cet article

How much power does the 1.1V DDR5 4800 kit draw under continuous load in the XR7620?

Each 32GB module operates at 1.10V; the four-module kit runs at the standard DDR5 4800 voltage with no extra power adapters required.

What must already be present in the Dell PowerEdge XR7620 for this 288-pin RDIMM kit to function?

The server needs free 288-pin DDR5 RDIMM slots and a BIOS that supports 2Rx8 registered ECC modules at 4800 MT/s.

Will the CL40 registered ECC modules work alongside existing RDIMMs of the same rank and voltage in the XR7620?

Yes, provided the installed DIMMs are also DDR5 4800 1.10V 2Rx8 registered ECC, the memory controller can train them together.
