Dell PowerEdge R7625 Compatible DDR5 Kit

This 32GB kit contains two 16GB DDR5 4800 registered DIMMs built for the Dell PowerEdge R7625 rack server. ECC and registered buffering protect data integrity in mission-critical workloads. IT professionals who need validated, stress-tested modules for enterprise environments will find the kit matches the platform’s native memory specification.

DDR5 4800 Registered ECC Interface Limits

The modules operate at the JEDEC-standard DDR5 4800 speed with CL40 latency and 1.10V voltage. Registered signalling adds one clock cycle of address-command delay, which is normal for server platforms. Systems that require higher frequencies, lower latencies or unbuffered DIMMs cannot use this memory without reducing stability or violating the server’s qualified vendor list.

32GB Dual-Rank Headroom

Two single-rank 1Rx8 modules populate two slots and deliver 32GB of error-correcting capacity. Workloads such as virtualisation, database caching and large-scale analytics fit comfortably within this footprint. Applications that demand more memory per channel or higher module density will exceed the kit’s capacity and require additional DIMMs or larger modules.

Questions about this item

Should I buy the 32GB kit or add single 16GB modules to reach the same total?

The kit provides two matched 16GB modules tested together for dual-channel operation, avoiding timing mismatches that can occur when mixing individual sticks.

What does the 4800 MT/s rating deliver inside a PowerEdge R7625?

At the rated 4800 MT/s the modules run at the platform's native DDR5 speed, giving maximum bandwidth without overclocking or manual tuning.

How does the RDIMM register affect usable speed on this server?

The registered buffer adds one cycle of latency but allows the memory controller to drive the full 4800 MT/s across all populated slots without signal degradation.
