Whether you are upgrading a single workstation, expanding RAM across a server fleet, or building out a new Cascade Lake compute cluster for virtualization, AI, database hosting, or 3D rendering workloads, this 16GB DDR4-2933 ECC RDIMM delivers the bandwidth, reliability, and platform compatibility that enterprise IT environments demand.

What the Module Name Means

Understanding the specification breakdown helps you confirm compatibility with your server or workstation:

• 16 GB is the capacity of one memory module
• DDR4 is the fourth-generation server and workstation memory standard
• PC4-2933Y indicates DDR4 memory running at 2933 MT/s, with the "Y" speed grade aligned to Intel Xeon Scalable Gen 2 (Cascade Lake)
• ECC stands for Error-Correcting Code, which detects and corrects single-bit memory errors automatically to prevent system crashes and data corruption
• Registered (RDIMM) means buffered memory with a register chip between the DRAM and the memory controller, allowing higher density and stability in multi-DIMM server configurations
• 288-pin DIMM is the standard physical form factor for DDR4 server and workstation memory

The "Y" speed grade label is specifically associated with Intel Xeon Scalable Gen 2 (Cascade Lake) platforms launched in 2019, which officially support DDR4-2933 RDIMM speeds on compatible motherboards.

Key Benefits of DDR4-2933 ECC RDIMM Memory

ECC Error Correction Protects Your Data Single-bit memory errors caused by cosmic rays, electrical interference, or component aging are automatically detected and corrected without crashing the system. For database servers, virtualization hosts, and financial computing workloads, ECC is non-negotiable.

Registered Architecture Supports High-Density Builds The register chip on RDIMM modules reduces electrical load on the memory controller, allowing you to populate more DIMMs per channel and reach memory capacities of 512GB, 1TB, or higher in a single server. Critical for in-memory databases, large VM hosts, and AI training nodes.

Officially Supported DDR4 Speed for Cascade Lake 2933 MT/s is the maximum officially supported DDR4 speed for Intel Xeon Scalable Gen 2 (Cascade Lake) processors. Using DDR4-2933 modules unlocks the full memory bandwidth your CPU was designed to deliver, with no performance penalty.

Backward Compatible DDR4-2933 modules will automatically downclock to 2666 MT/s on Xeon Scalable Gen 1 (Skylake-SP) platforms, giving you forward-compatible inventory that works across multiple server generations.
