DELL W403Y 64GB DDR4 2933MHz ECC Registered DIMM

SKU CH-HXMJ-HFC0Q

64 GB DDR4 module with ECC error correction and registered signal processing at 2933 MHz

  • TypeRAM Module
  • 64 GB capacity enables large workloads in a single module
  • ECC registered design protects data integrity for servers
  • 2933 MHz DDR4 speed supports high-throughput applications
  • 20 V operation reduces power draw per module
  • 288-pin DIMM fits standard PC and server slots

64GB DDR4 ECC Registered DIMM

This single 64GB DDR4 module delivers 2933MHz speed with ECC error correction and registered signal processing for data-integrity workloads. It operates at 1.20V and uses a 288-pin DIMM form factor suited to compatible servers and workstations. The dual-rank design supports high-density memory configurations.

Dual-rank 64GB density

The dual-rank 64GB capacity on one DIMM is the specification that determines fit for high-density memory slots in supported Dell platforms. Systems limited to single-rank modules or lower maximum capacities per slot cannot use this part. Verify the platform's qualified vendor list and maximum rank-per-channel allowance before ordering.

Low-voltage DDR4 thermals

Running at 1.20V, the module generates modest heat under typical server workloads and relies on chassis airflow for cooling. No active cooling is integrated and acoustic output is negligible in normal operation. Power draw scales with access patterns but remains within standard DDR4 limits for registered DIMMs.

Questions about this item

How much capacity does the 64 GB module add to a server?

The single 64 GB DIMM increases total system memory by 64 GB when installed in a compatible slot.

What does the DDR4-2933/PC4-23400 rating limit in practice?

The module runs at up to 2933 MHz with a peak transfer rate of PC4-23400; the platform memory controller sets the actual operating speed.

Will the 288-pin DIMM fit a standard server memory slot?

Yes, the 288-pin DDR4 DIMM form factor matches the standard slot used in compatible Dell PC and server platforms.
