Server memory for PowerEdge C4140

This 64GB DDR4 ECC registered RDIMM is built for the PowerEdge C4140 with SkyLake CPUs. It targets administrators who need to expand capacity in a validated server platform without mixing memory types.

288-pin registered design with JEDEC compliance

The module uses a 4Rx4 layout at 1.2V and carries no heat spreader. Registered buffering prevents use in standard desktops and forbids mixing with unbuffered or load-reduced DIMMs in the same system.

Replaces slower DDR4 or fills empty slots

Backward compatible with 2133MHz, 2400MHz and 2666MHz modules, so it can upgrade existing banks or populate new ones. Not for workstations that require unbuffered memory or consumer boards lacking registered support.

I korthet

  • ECC registered design protects data integrity in servers
  • 64GB single module maximises capacity per slot
  • DDR4 2933MHz CL21 speed matches system spec
  • 2V operation reduces power draw and heat

Frågor om den här produkten

What DDR4 speed and PC4 rating does this 64GB module run at?

It operates at DDR4 2933 MHz with a PC4-23400 data-rate and CL21 latency.

What physical slot and form factor does this 288-pin RDIMM require?

It fits a standard 288-pin DDR4 RDIMM socket in the PowerEdge C4140; no heat spreader is present.

How do I install this ECC Registered module and what common mistake should I avoid?

Power down the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until the ejector tabs click, then verify the BIOS reports 64 GB at 2933 MHz; do not mix this 4Rx4 registered DIMM with unbuffered or load-reduced memory.
