Server-grade memory kit for PowerEdge C4140

This 128GB kit supplies eight 16GB DDR4 2933 ECC registered RDIMMs built for the PowerEdge C4140 with SkyLake CPUs. It targets administrators who need to maximise capacity in that specific platform without mixing registered and unbuffered modules.

Steady throughput under registered ECC operation

Registered buffering and ECC correction keep data integrity intact during continuous multi-threaded workloads typical of virtualisation or database tasks. The modules run at 1.2V and fall back to 2133MHz, 2400MHz or 2666MHz when the system demands lower speeds.

Straightforward DIMM installation

Each 288-pin module slots into the C4140 memory channels without tools or heat spreaders to remove. The kit will not work in standard desktops and cannot be combined with unbuffered or load-reduced ECC memory, so verify the platform before ordering.

Questions about this item

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

Each module operates at 1.2V, the standard DDR4 voltage, so the eight 16 GB sticks together run at the same low voltage as any JEDEC DDR4 2933 kit.

What must the server already have for this 8 x 16 GB registered ECC kit to work?

The PowerEdge C4140 must support DDR4 registered ECC RDIMMs with 2Rx4 organisation and 288-pin slots; it cannot accept unbuffered or load-reduced DIMMs.

Will these 2933 MHz modules run with the slower 2133, 2400 or 2666 MHz DIMMs already in the C4140?

Yes, the kit is backward compatible with 2133, 2400 and 2666 MHz speeds, so it will down-clock to match any slower DDR4 registered ECC memory already installed.
