Server-grade ECC RDIMM kit

This OWC kit supplies 128GB of DDR4 memory across eight 16GB registered DIMMs. It is built for the PowerEdge C4140 with CascadeLake CPUs and will not work in standard desktop computers or alongside unbuffered or load-reduced modules.

Sustained workload stability

Registered buffering and ECC correction keep data integrity intact during continuous server and workstation tasks. The modules also run at 2133, 2400 or 2666MHz when the platform requires a lower speed.

2933MHz CL21 registered specification

The decisive figure is the DDR4 2933 CL21 registered profile at 1.2V. Buyers whose systems demand a different speed, latency or unbuffered design must choose another kit.

Preguntas sobre este artículo

How much power does the 1.2V DDR4 2933 kit draw when the PowerEdge C4140 runs all day?

Each module operates at 1.2 volts, the standard DDR4 voltage, so total draw scales with the eight 16 GB sticks installed.

What must the server already have to accept this 288-pin ECC registered RDIMM kit?

A PowerEdge C4140 with Cascade Lake CPUs and free DDR4 RDIMM slots that support registered ECC memory.

Will these CL21 2933 MHz modules run with older 2133 MHz DIMMs left in the chassis?

Yes, the kit is backward compatible with 2133, 2400 and 2666 MHz speeds, though all channels will run at the slowest installed rate.
