Rank 1Rx8

  • 32 GB kit (2 × 16 GB) for high-capacity server workloads
  • DDR5 4800 MT/s PC5-38400 speed for fast data throughput
  • CL40 CAS latency at 1.10 V for efficient operation
  • ECC registered RDIMM with 1Rx8 rank for error correction and signal integrity
  • Validated for Dell PowerEdge R660xs compatibility

Dell PowerEdge R660xs Compatible DDR5 ECC RDIMM Kit

This 32 GB kit contains two 16 GB registered DDR5 modules built for the Dell PowerEdge R660xs server. ECC and registered buffering protect data integrity in mission-critical workloads. The modules run at 1.10 V and use a standard 288-pin form factor. IT professionals receive a validated upgrade path for this specific platform.

Upgrading from Lower-Capacity or Slower DDR5 RDIMMs

Replacing smaller RDIMMs or slower DDR5 speeds with this 32 GB CL40 kit adds both capacity and bandwidth headroom. The jump is worthwhile when virtualization density, database caching or compute-node consolidation demand more memory per channel. Existing registered ECC modules of lower speed or rank count can be displaced to balance channel population.

32 GB Total Capacity for Virtualization

Two 1Rx8 modules populate two slots and leave remaining channels open for future expansion. The 4800 MT/s rate and CL40 latency handle typical enterprise VMs, container clusters and in-memory databases comfortably. Workloads that exceed 32 GB per server or require higher memory bandwidth per core will need additional modules or faster-rated kits.

Questions about this item

What slot spacing and pin count does the 288‑pin DDR5 RDIMM kit need in the Dell PowerEdge R660xs?

The kit uses standard 288‑pin DDR5 RDIMM modules; they fit the native DDR5 slots on the R660xs motherboard with no adapter required.

Which orientation step is most often missed when seating the 1Rx8 registered DIMMs?

Align the off‑centre notch on each 16GB module with the slot key, press straight down until both retention clips click, and verify the modules are fully seated before powering on.

How can I tell when the ECC registered modules should be replaced in a Dell PowerEdge R660xs?

Monitor the system event log for corrected ECC error counts; a sustained rise above the platform threshold signals the DIMMs should be swapped before uncorrectable errors appear.
