CMS 64GB DDR4-2133 ECC Registered Kit

This 64GB kit contains four 16GB DDR4 modules rated at 2133MHz with CL15 timings and 1.2V operation. It is built as ECC Registered DIMMs for Dell PowerEdge R430, R530 and T430 servers. The 288-pin design fits the specific memory architecture of these platforms.

Installation Notes and Common Issues

The modules install into standard 288-pin DDR4 slots on the supported Dell PowerEdge systems. Mixing these Registered ECC modules with Unbuffered ECC memory is not supported within the same system. Additionally, 4GB Registered ECC modules using x4 and x8 DRAM organisations must not be combined within a single memory bank.

Sustained Load Behaviour

The ECC Registered design provides error correction and signal buffering that maintains data integrity during continuous server workloads. Operation at the specified 1.2V helps manage thermal output across all four modules. The kit supports the platform maximum of 384GB when fully populated with compatible Registered ECC DIMMs.

Questions about this item

How can I verify the CM2048722133ECCREG kit is running at the correct 2133 MHz CL15 after installation?

Enter the server BIOS or UEFI and confirm the memory frequency reads 2133 MHz with timings 15-15-15 at 1.2 V. The POST screen should also show 64 GB total across four registered ECC DIMMs.

What does the package contain and is anything else required for installation in a PowerEdge R430?

The box includes four 16 GB 288-pin DDR4 registered ECC DIMMs. No extra parts are needed; the modules install directly into the server’s memory slots.

Which registered ECC module version should I choose for a Dell PowerEdge R530 bank — the 313 or 3138 variant?

Use the same DRAM organisation within each bank. The 313 part uses x4 chips and the 3138 uses x8 chips; they can coexist in the system but not in the same memory bank.
