OWC 128GB DDR5 5600 ECC Registered RDIMM 4Rx4 CL46 1.1V memory upgrade

Server-grade DDR5 RDIMM for Gigabyte R183 systems

This 128GB DDR5 5600 ECC Registered module is built for Gigabyte R183-S90, R183-S91, R183-S92, R183-S93 and R183-S94 servers. It targets administrators expanding memory in compatible workstations, NAS units or network switches. The single 288-pin DIMM delivers 128GB capacity at 1.1V with CL46 latency. It will not function in standard desktop platforms or alongside unbuffered or load-reduced DIMMs.

Sustained reliability

Error-correcting code detects and corrects single-bit errors during continuous operation, while the registered buffer reduces electrical load on the memory controller. This combination maintains data integrity under heavy, prolonged workloads typical of virtualisation hosts or database servers. The JEDEC-standard PC5-44800 timing ensures stable throughput without relying on overclocking headroom.

4Rx4 rank density decides slot efficiency

The quad-rank 4Rx4 organisation packs 128GB into one slot, which maximises capacity on boards with limited DIMM positions. Systems that cannot address four ranks per channel will not recognise the full capacity, so verifying the platform rank limit is essential before purchase.
