Capacity and role

This 32 GB registered DDR4 module is built for memory-intensive server and workstation platforms. The single-rank 1Rx4 layout and parity ECC suit hyperscale, virtualization, cloud and big-data deployments that demand density and data integrity.

Sustained-load behaviour

Registered buffering reduces the electrical load on the CPU memory controller, enabling stable operation across fully populated channels. The 1.20 V operating voltage and CL22 22-22-22 timings at 3200 MHz deliver consistent throughput without heat-spreader overhead.

Upgrade context

The module replaces lower-capacity or unbuffered DIMMs when a platform requires registered parity memory and can address 32 GB per slot. The jump is worthwhile when workloads exceed the capacity or signal-integrity limits of the existing configuration.

Questions about this item

Does the 1.20V LRDIMM design keep power draw low when the 32GB module runs continuously in a server?

The registered 1Rx4 module operates at 1.20V and is built to reduce electrical load on the CPU, which helps limit heat and power consumption during sustained workloads.

What motherboard feature is required to use this registered parity DDR4 3200 module?

The system must support registered LRDIMMs with parity ECC and be able to run DDR4 at 3200 MT/s (PC4-25600) with CL22 timing.

Can this CL22 3200 module share a channel with slower DDR4 DIMMs already installed?

All DIMMs on a channel run at the speed and timing of the slowest module, so this CL22 3200 part will down-clock to match older DDR4 memory.
