G.SKILL F5-5600R2834F32GQ4-G5N 128GB (4×32GB) DDR5-5600 ECC Registered R-DIMM server RAM

128GB DDR5 ECC Registered R-DIMM

This G.SKILL G5 Neo kit delivers 128GB of DDR5 server memory across four 32GB modules. It uses registered R-DIMM topology with on-board ECC for data integrity in multi-socket platforms. The quad-channel kit runs at DDR5-5600 with 288-pin connectors. It targets administrators building or expanding memory capacity in compatible enterprise servers and workstations.

Registered R-DIMM slot and channel requirements

Verify that the motherboard accepts registered DDR5 R-DIMMs and supports quad-channel population for this 4-module kit. The platform must provide four 288-pin DDR5 slots wired for the intended channel layout. ECC functionality requires a CPU and chipset that expose the error-correction path; unbuffered or consumer boards will not post with these modules. Confirm maximum supported capacity per slot and per channel in the system documentation before ordering.

Sustained throughput with registered buffering

The register on each R-DIMM adds one cycle of buffering, stabilising the command bus during continuous heavy traffic such as database caching or virtualisation workloads. ECC correction operates transparently during extended runs, preventing silent data corruption without software overhead. DDR5-5600 bandwidth is maintained across all four channels as long as the memory controller keeps the ranks populated and thermals stay within the platform limits. No fan is included, so chassis airflow must handle the module heat load during prolonged operation.
