  • 2933MHz DDR4 speed with CL21 latency
  • 2V operation lowers power draw
  • Validated for PowerEdge C4140 with CascadeLake CPUs

Target system and purpose

This is a single 64GB DDR4 ECC Registered RDIMM built for the PowerEdge C4140 with CascadeLake CPUs. It suits administrators expanding memory capacity in compatible Dell servers or workstations.

Compatibility checks

Verify the server uses registered ECC DDR4 and does not mix unbuffered or load-reduced modules. Confirm the platform accepts 2933MHz CL21 2Rx4 288-pin 1.2V DIMMs and that the CPU is a CascadeLake model.

Build integration

The module plugs into a standard 288-pin DDR4 slot and operates at 1.2V. It replaces Dell part numbers AA579530 AA601615 AB003154 SNPW403YC/64G SNPW403YC/64VXR W403Y and supports backward speeds of 2133MHz 2400MHz 2666MHz.

Pluspunten

  • ECC registered design protects data integrity in servers
  • 64GB capacity in a single 2Rx4 module
  • 2933MHz DDR4 speed with CL21 latency
  • 2V operation lowers power draw
  • Validated for PowerEdge C4140 with CascadeLake CPUs

Vragen over dit artikel

What comes inside the package and what must I buy separately?

The box contains one 64GB DDR4 2933 CL21 2Rx4 288-pin 1.2V ECC Registered RDIMM module. No extra parts or cables are required for installation in a compatible PowerEdge C4140 server.

Which capacity or version should I select for my PowerEdge C4140?

This single module provides 64GB at 2933MHz CL21. Choose it when you need a registered ECC DIMM that matches the server's DDR4 2933 specification and replaces Dell part numbers AA579530, AA601615, AB003154, SNPW403YC/64G or W403Y.

What does the 2933MHz rating mean once the module is installed?

The module runs at DDR4 2933 (PC4-23400) with CL21 latency at 1.2V. It is backward compatible with 2133MHz, 2400MHz and 2666MHz bus speeds, so it will operate at the highest speed the C4140 platform supports.
