Lenovo 4 GB DDR4-2133 RDIMM 46W0784 | Server Memory, ECC, Low Profile

Keep critical infrastructure responsive with Lenovo 4 GB DDR4-2133 RDIMM, designed for server platforms that need registered memory, error correction, and compact thermal clearance. This module pairs 2,133 MHz data rate with CL15 timing to support steady access patterns in business systems where consistency matters more than peak headline speed. The low-profile form factor is a practical advantage in dense rack environments, especially where airflow, heatsinks, and adjacent components limit clearance. Registered DIMM architecture helps reduce electrical load on the memory controller, which is why RDIMMs are commonly selected for multi-slot server configurations and workloads that run continuously. At 4 GB per module, this part is suited to targeted capacity expansion, replacement planning, or maintaining platform compatibility in Lenovo server environments that specify PC4-17000 DDR4 memory. It is the kind of component procurement teams choose when they need the right module, not a generic substitute. For infrastructure teams, that means fewer compatibility questions, cleaner serviceability, and a memory upgrade path aligned to the original system design.
