128GB DDR4 2133 ECC Registered Server Memory

This 128GB DDR4 2133 module provides error-correcting, registered memory for enterprise servers and workstations. The 288-pin DIMM operates at PC4 17000 speed with a 4Rx4 rank structure. It targets administrators who need high-capacity, reliable RAM for multi-socket platforms and virtualization hosts.

ECC Registered with 4Rx4 organisation

Error-correcting code detects and corrects single-bit errors while the registered buffer reduces electrical load on the memory controller. The quad-rank x4 layout allows the 128GB density in a single slot. These features together maintain data integrity and signal stability in dense, mission-critical deployments.

DDR4 2133 bandwidth ceiling

The PC4 17000 interface caps peak transfer rate at 17 GB/s per module, limiting throughput for memory-bound workloads. Systems requiring higher bandwidth must populate additional channels or select faster DDR4 speeds. This module cannot exceed the 2133 MT/s data rate defined by its SPD profile.

Questions about this item

Will the 4Rx4 registered DDR4 modules need replacement after a certain service interval?

The 4Rx4 registered DDR4 2133 modules have no defined service interval; they are solid-state components rated for continuous operation in enterprise servers.

What limit appears first when the 128GB kit runs at DDR4 2133 under sustained load?

The DDR4 2133 (PC4 17000) speed rating is the ceiling; bandwidth and latency are fixed by the JEDEC specification for this frequency.

How much extra heat does the registered ECC DDR4 2133 kit produce when running all day?

Registered ECC DDR4 2133 modules draw standard DDR4 voltage; thermal output matches the JEDEC power envelope for 288-pin DIMMs at this speed.
