SK Hynix - DDR5 - module - 32 GB - RDIMM 288-PIN - PC5-38400B-R - 4800MHZ 2RX8

For servers and workstations that demand uncompromising data integrity under continuous load, this SK Hynix 32GB DDR5 registered DIMM stands apart from unbuffered desktop memory. Its on-module register buffers command and address signals, enabling stable operation across densely populated multi-slot server boards where signal integrity is paramount. The result is a module engineered for virtualization, in-memory databases, and enterprise workloads that cannot tolerate silent data corruption.

Highlights

• 32 GB capacity on a single 288-pin RDIMM, balancing density and cost per gigabyte.
• DDR5-4800 (PC5-38400B-R) delivers 38.4 GB/s peak bandwidth per channel.
• Integrated ECC detects and corrects single-bit errors, a critical safeguard for 24/7 operation.
• Dual-rank x8 organization improves interleaving and memory-level parallelism.
• Operates at just 1.1 V, reducing power draw and thermal load compared to DDR4.
• Standard-profile module without heat spreader fits 1U and blade server chassis.

In daily use

Populate a dual-socket server with these modules and you gain headroom for large-scale consolidation. The registered design maintains clean signal timing even when all DIMM slots are filled, while CL40 latency keeps response times predictable under mixed read/write bursts. Because the module is unbuffered in the data path but registered for control signals, it avoids the latency penalty of fully buffered memory while still supporting high capacities per channel. In practice, this means fewer application stalls during backup windows, database checkpoints, or live migration events.
