Capacity and compatibility

This is a 64GB DDR5 ECC RDIMM module built for the Dell PowerEdge XR7620 rack server. It delivers registered, error-correcting memory for workloads that require data integrity and system stability. The single-module design suits upgrades where slot count is limited.

Speed and latency envelope

The module runs at 4800 MT/s with a CAS latency of CL40 and operates at 1.1V. These JEDEC-standard timings define the practical throughput ceiling for the platform; faster data rates or tighter latencies are not supported by this part. Buyers needing higher bandwidth must verify whether the server accepts faster DDR5 SKUs.

Physical build and daily handling

The stick uses a standard 288-pin DDR5 form factor without a heat spreader, relying on server chassis airflow for cooling. Major OEM DRAM chips from Samsung, Micron or Hynix are used. The registered design adds a buffer that increases signal integrity but requires motherboard support for RDIMMs; it will not function in unbuffered DIMM slots.

Perguntas sobre este artigo

Is the 64 GB module the only capacity offered for this Dell PowerEdge XR7620 compatible DDR5 4800 ECC RDIMM?

The listed package contains a single 64 GB module (1X64GB); other capacities are not described for this part number.

What does the CL40 latency mean for real-world throughput in a Dell PowerEdge XR7620 running DDR5 4800?

CL40 indicates 40 clock cycles of CAS latency at the 4800 MT/s data rate; actual throughput depends on the server's memory controller and workload mix.

The module is a 288-pin DDR5 RDIMM — does that interface cap the speed at 4800 MT/s in the XR7620?

The 288-pin DDR5 RDIMM form factor supports the rated 4800 MT/s; the XR7620's memory controller determines the maximum operating speed.
