Server Memory Upgrade

This 128GB DDR5 ECC Registered RDIMM is built for Gigabyte R183-S95, R183-S96, R183-S97, R183-SF0 and R183-SF1 systems. It targets administrators who need to expand capacity in compatible workstations, servers, NAS devices or network switches. The module will not work in standard desktop computers.

Compatibility Constraints

The product ships as a single 128GB stick with no heat spreader. Because it is Registered ECC, it cannot be mixed with unbuffered or load-reduced DIMMs in the same platform. JEDEC and RoHS compliance ensures the upgrade meets OEM specifications without voiding the original system warranty.

Registered ECC Design

The 4Rx4 rank configuration and 1.1V operating voltage define the electrical load presented to the memory controller. This specification determines whether the module can populate a given slot in the supported Gigabyte platforms. Buyers must verify their system accepts Registered ECC before purchasing.

Questions about this item

When will the 128GB DDR5 5600 CL46 4Rx4 RDIMM need replacement in a Gigabyte R183-S95 server?

The module is built to JEDEC and RoHS standards with a limited lifetime warranty; under normal server workloads it typically lasts the useful life of the platform.

What thermal or power limit appears first when the 1.1V 288-pin ECC registered DIMM runs sustained loads in a Gigabyte R183-S96?

At 1.1V the module stays within JEDEC power envelopes; the system’s memory-controller thermal limit is reached before the DIMM itself throttles.

How much extra noise or heat does the 128GB DDR5 5600 RDIMM add when a Gigabyte R183-SF0 operates continuously?

The stick has no heat spreader and draws only 1.1V, so it contributes minimal additional heat and zero acoustic noise; system fans dominate both.
