64GB DDR4 ECC RDIMM for Dell servers

This module delivers 64 GB of DDR4-3200 registered memory with error-correcting code for Dell server platforms. It operates at 3200 MHz with a CAS latency of 22 and a standard voltage of 1.20 V. The 288-pin RDIMM form factor fits compatible DDR4 server slots.

ECC and registered design protect data integrity

Error-correcting code detects and corrects single-bit errors while the register buffers address and command signals for stable operation under heavy loads. These features reduce the risk of silent data corruption in virtualisation, database and high-availability workloads. The module is validated for the Dell part number SNPP2MYXC/64.

Single-rank capacity limits total DIMM count

Each stick provides 64 GB in a single rank, so the maximum memory a server can hold depends on how many RDIMM slots the platform exposes. Builders who need more total capacity than the slot count allows should consider higher-density modules if the platform supports them. The module first appeared on the manufacturer list on 21 August 2025.

Questions about this item

Will the 64 GB DDR4-3200 ECC RDIMM need replacement if a DIMM slot fails?

The module itself has no moving parts; only a motherboard slot failure would require replacement of the board, not the memory.

What limits sustained throughput on this 3200 MHz CL22 registered kit?

The DDR4-3200 interface and CL22 latency set the maximum bandwidth ceiling under continuous load.

How much heat does the 1.20 V registered DIMM produce during all-day operation?

At 1.20 V the module runs within standard DDR4 thermal limits, so typical server airflow keeps temperatures in check.
