System-specific DDR4 kit

This 64 GB kit contains two 32 GB DDR4 2933 registered ECC RDIMMs built for the Dell PowerEdge C4140 with Cascade Lake processors. It is intended for server, workstation and NAS administrators who need validated, registered memory for those platforms.

Compatibility checklist

Verify that the target system is a PowerEdge C4140 running Cascade Lake CPUs and that all populated slots use registered ECC modules; this kit will not work in standard desktops and must not be mixed with unbuffered or load-reduced DIMMs.

Build integration

The modules operate at 1.2 V, run at CL21 latency and are backward compatible with 2133, 2400 and 2666 MT/s bus speeds, freeing you to populate matching slots without raising voltage or changing memory timings.

Questions about this item

What is included in the box and does anything need to be purchased separately?

The kit contains two 32 GB DDR4 2933 ECC Registered RDIMM modules for a total of 64 GB. No additional parts are required for installation in a compatible PowerEdge C4140.

Which capacity option should I choose for my PowerEdge C4140 with Cascade Lake CPUs?

This 64 GB kit (2 × 32 GB) is the specific configuration validated for the PowerEdge C4140 running Cascade Lake processors.

What does the 2933 MHz rating mean once the modules are installed in the server?

The modules run at 2933 MHz (PC4-23400) with CL21 latency at 1.2 V and will also operate at 2666, 2400 or 2133 MHz if the system requires a lower speed.
