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.

Perguntas sobre este artigo

Does the 1.1 V registered DIMM draw noticeably more power or run hotter than standard server memory during continuous operation?

Operating at 1.1 V, the module follows the JEDEC DDR5 baseline voltage, so its power draw and thermal output are comparable to other registered DDR5 DIMMs under sustained load.

Will this 288-pin DDR5 5600 CL46 4Rx4 module work in my Gigabyte R183-S92 server without any additional hardware?

Yes — the DIMM is validated for the R183-S90 through R183-S94 platforms; simply install it into a free DDR5 RDIMM slot on the motherboard.

Can I mix this 128 GB 4Rx4 ECC registered stick with the 2Rx4 registered DIMMs already in my R183-S91?

Mixing different rank configurations is generally supported on these platforms, but the memory controller will run all channels at the lowest common speed and latency; check the system manual for population rules.
