Dell PowerEdge XR7620 memory kit

This 128 GB kit contains two 64 GB DDR5 registered DIMMs built for the Dell PowerEdge XR7620 rack server. ECC and registered buffering protect data integrity in mission-critical workloads. The modules run at 4800 MT/s with CL40 latency at 1.1 V. No heat spreaders are fitted.

288-pin RDIMM form factor

Each module uses the standard 288-pin DDR5 RDIMM connector, so installation follows the server's documented memory population rules. Registered signalling reduces electrical load on the memory controller, allowing the full two-module population. The 2Rx4 organisation matches the platform's supported rank configuration.

DDR5 4800 registered ECC limits

The DDR5 4800 interface caps transfer rate at 38 400 MB/s per module, and CL40 latency is fixed by the JEDEC base specification. Registered ECC operation adds one cycle of command buffering, which cannot be disabled. Systems that require unbuffered or non-ECC memory cannot use this kit.

商品問答

What speed does the DDR5 4800 interface run at in this kit?

The modules operate at DDR5 4800 (PC5-38400) with a CAS latency of CL40.

What physical slot and form factor are required for these 288-pin RDIMMs?

They fit a standard 288-pin DDR5 RDIMM slot; no heat spreader is present, so clearance is minimal.

How do I install the two 64 GB modules in a Dell PowerEdge XR7620, and what step is often missed?

Power down, open the chassis, align each module with the keyed slot and press firmly until the ejector clips lock; the step often missed is verifying the memory configuration in the BIOS after boot.
