OWC 3R2D42R432GB 32GB DDR4 3200 ECC RDIMM for Dell PowerEdge C6520 C6525 MX750c R650 R650xs

Server-specific ECC RDIMM

This OWC module is a 32GB DDR4 3200 ECC registered DIMM built for Dell PowerEdge C6520, C6525, MX750c, R650 and R650xs servers. It runs at 1.2V with CL22 latency and a 2Rx4 rank configuration on a 288-pin form factor. The part is validated as a direct replacement for Dell part numbers including 370AEVN and 75X1V. It is not compatible with standard desktop computers or unbuffered memory configurations.

Capacity and registered headroom

The 32GB capacity suits virtualization hosts, database nodes and multi-tenant workloads that benefit from error-correcting registered memory. Registered buffering reduces electrical load on the memory controller, allowing higher total system capacities than unbuffered alternatives. The module will not serve workloads that require larger individual DIMM densities or non-ECC consumer platforms. Mixing with unbuffered DIMMs is not supported and will prevent operation.

DDR4 3200 interface limits

The PC4-25600 rating defines the maximum JEDEC-standard data rate for this DDR4 generation. Real-world throughput depends on the specific PowerEdge model, CPU memory controller capabilities and populated DIMM slots per channel. Population rules for the listed servers may reduce the effective speed below 3200 MT/s when all channels are fully loaded. The module does not support speeds or voltages outside the DDR4 3200 1.2V specification.
