32GB DDR4-2933 ECC registered server memory

This 32GB DDR4 module runs at 2933 MT/s with a PC4-23400 rating. It operates at 1.20V and includes error-correcting code plus registered buffering for data integrity. The part targets servers and workstations that require registered DIMMs.

Verify motherboard support for registered ECC DDR4

Confirm the platform accepts registered DIMMs and can operate memory at 1.20V. Unbuffered or non-ECC boards will not work with this module. Check the qualified vendor list for the exact part number M393A4K40CB2-CVF before ordering.

Fits DDR4 RDIMM slots in multi-socket servers

The registered design reduces electrical load on the memory controller, allowing larger total capacities per channel. ECC protects against single-bit errors in critical workloads. Systems that require unbuffered or non-ECC memory cannot use this module.

Questions about this item

Does the M393A4K40CB2-CVF module ship alone or in a kit with multiple sticks?

The part number refers to a single 32 GB DDR4 2933 registered ECC DIMM. Order the exact quantity your server requires; no extra cables or brackets are included.

When should I choose this 32 GB DDR4 2933 registered ECC stick over a lower-capacity or unbuffered alternative?

Select it when your platform demands registered ECC memory and you need the maximum density per slot at the 2933 MT/s speed rating.

Will the PC4 23400 rating deliver its full 2933 MT/s throughput in my server?

The module runs at 2933 MT/s when the memory controller and BIOS support that speed; otherwise it down-clocks to the highest common JEDEC frequency.
