Rank 4Rx4

  • 128GB single-module capacity maximises slot density
  • ECC registered design protects data integrity in servers
  • 2933MHz DDR4 speed with CL21 latency boosts throughput
  • 2V operation reduces power draw per module
  • Backward compatible with 2133, 2400 and 2666MHz systems

Single 128GB ECC RDIMM for Servers

This module provides 128GB of DDR4 2933MHz registered memory in a single 288-pin slot. It operates at 1.2V with CL21 latency and features 4Rx4 organisation for high-density capacity. The ECC registered design ensures data integrity for critical server and workstation workloads.

Suited for JEDEC DDR4 Platforms Only

It fits servers, workstations and NAS systems that accept DDR4 2933MHz ECC RDIMMs and support backward compatibility at 2133MHz, 2400MHz or 2666MHz. Buyers with standard desktop PCs or laptops cannot use this memory, and systems requiring unbuffered or non-ECC modules must look elsewhere.

Registered ECC with 4Rx4 Density

The registered buffer and 4Rx4 rank configuration define electrical loading and compatibility with the memory controller. Verify that your platform supports registered ECC RDIMMs and 4Rx4 density before purchasing.

Questions sur cet article

What comes inside the package and do I need to buy any additional parts?

The package contains one 128GB 288-pin DDR4 ECC Registered RDIMM. No extra cables, brackets or heat spreaders are required for installation.

Should I choose the 128GB 4Rx4 module or look for a different capacity or rank configuration?

This listing is a single 128GB 4Rx4 module. Select it when your server or workstation needs maximum capacity per slot and supports 4Rx4 registered ECC memory.

What does the 2933MHz CL21 rating mean once the module is installed in a server?

The module runs at 2933MHz with CL21 latency at 1.2V and will down-clock to 2666, 2400 or 2133MHz if the platform requires a lower speed.
