PowerEdge C4140 DDR4 ECC RDIMM Kit

This 32GB kit contains two 16GB DDR4 2933 modules built to JEDEC PC4-23400 CL21 specifications. The 288-pin registered DIMMs operate at 1.2V and include ECC error correction for data integrity. They are validated specifically for the PowerEdge C4140 platform with SkyLake CPUs.

Server and workstation upgrades only

The modules suit administrators expanding memory in a compatible Dell PowerEdge C4140 or similar registered-ECC platform. They will not work in standard desktop boards, consumer laptops or any system that requires unbuffered or load-reduced DIMMs. Buyers needing non-ECC memory should look elsewhere.

Ready-to-install dual-module kit

The package delivers a matched pair so the server can populate two slots immediately without mixing ranks or speeds. Backward compatibility with 2133, 2400 and 2666MHz buses allows the kit to clock down automatically if the platform demands it. No heat spreaders are included, relying on system airflow for cooling.

Questions sur cet article

What server must I already have for this 288-pin ECC registered kit to install correctly?

The modules are validated for the PowerEdge C4140 with a SkyLake CPU and will not work in standard desktop systems.

Can I keep my existing 2133 MHz or 2400 MHz DDR4 ECC registered DIMMs and add this 2933 MHz kit alongside them?

Yes, the kit is backward compatible with 2133 MHz, 2400 MHz and 2666 MHz ECC registered memory, though all modules will run at the speed of the slowest installed DIMM.

How do I confirm the 32 GB kit is running at 2933 MHz with ECC active after installation?

Check the system BIOS or a hardware utility such as IPMI; it should report 32 GB total, 2933 MT/s data rate, CL21 timings, 1.2 V and ECC registered mode enabled.
