32GB Registered DDR4 Server Module

This SK hynix module provides 32GB of DDR4-2933 registered ECC memory in a 288-pin dual-rank design. It is built for servers and workstations that require error correction and signal buffering for stable operation.

Fits Registered DDR4 Platforms

The module installs in 288-pin DDR4 slots that support registered memory and ECC. Its registered buffer reduces electrical load on the memory controller, freeing the platform to populate more slots per channel.

Sustained Load With ECC Protection

Error-correcting code detects and corrects single-bit errors during continuous operation, preventing data corruption under sustained workloads. CL21 latency and DDR4-2933 bandwidth deliver consistent throughput for long-running server tasks.

Questions about this item

Does the CL21 latency become a bottleneck during sustained server workloads?

CL21 is the rated CAS latency at 2933 MHz; sustained throughput depends on the memory controller and rank interleaving in your platform.

What thermal or power behaviour should I expect when this registered DIMM runs continuously?

Registered DDR4 modules draw slightly more power than unbuffered equivalents, but the supplier provides no specific TDP or temperature figures for this part number.

Which motherboard features are required for this 288-pin registered ECC module to function?

The board must support DDR4-2933 registered ECC memory with dual-rank 32 GB DIMMs on a 288-pin slot.
